ROCm 5.7.1#

What’s New in This Release#

ROCm Libraries#

rocBLAS#

A new functionality rocblas-gemm-tune and an environment variable ROCBLAS_TENSILE_GEMM_OVERRIDE_PATH are added to rocBLAS in the ROCm 5.7.1 release.

rocblas-gemm-tune is used to find the best-performing GEMM kernel for each GEMM problem set. It has a command line interface, which mimics the –yaml input used by rocblas-bench. To generate the expected –yaml input, profile logging can be used, by setting the environment variable ROCBLAS_LAYER4.

For more information on rocBLAS logging, see Logging in rocBLAS, in the API Reference Guide.

An example input file: Expected output (note selected GEMM idx may differ): Where the far right values (solution_index) are the indices of the best-performing kernels for those GEMMs in the rocBLAS kernel library. These indices can be directly used in future GEMM calls. See rocBLAS/samples/example_user_driven_tuning.cpp for sample code of directly using kernels via their indices.

If the output is stored in a file, the results can be used to override default kernel selection with the kernels found, by setting the environment variable ROCBLAS_TENSILE_GEMM_OVERRIDE_PATH, where points to the stored file.

For more details, refer to the rocBLAS Programmer’s Guide.

ROCm 5.7.0#

Release highlights for ROCm 5.7#

ROCm 5.7.0 includes many new features. These include: a new library (hipTensor), and optimizations for rocRAND and MIVisionX. Address sanitizer for host and device code (GPU) is now available as a beta. Note that ROCm 5.7.0 is EOS for MI50. 5.7 versions of ROCm are the last major release in the ROCm 5 series. This release is Linux-only.

Important: The next major ROCm release (ROCm 6.0) will not be backward compatible with the ROCm 5 series. Changes will include: splitting LLVM packages into more manageable sizes, changes to the HIP runtime API, splitting rocRAND and hipRAND into separate packages, and reorganizing our file structure.

AMD Instinct™ MI50 end-of-support notice#

AMD Instinct MI50, Radeon Pro VII, and Radeon VII products (collectively gfx906 GPUs) will enter maintenance mode starting Q3 2023.

As outlined in 5.6.0, ROCm 5.7 will be the final release for gfx906 GPUs to be in a fully supported state.

  • ROCm 6.0 release will show MI50s as “under maintenance” mode for Linux and Windows

  • No new features and performance optimizations will be supported for the gfx906 GPUs beyond this major release (ROCm 5.7).

  • Bug fixes and critical security patches will continue to be supported for the gfx906 GPUs till Q2 2024 (EOM (End of Maintenance) will be aligned with the closest ROCm release).

  • Bug fixes during the maintenance will be made to the next ROCm point release.

  • Bug fixes will not be backported to older ROCm releases for gfx906.

  • Distribution and operating system updates will continue as per the ROCm release cadence for gfx906 GPUs till EOM.

Feature updates#

Non-hostcall HIP printf#

Current behavior

The current version of HIP printf relies on hostcalls, which, in turn, rely on PCIe atomics. However, PCle atomics are unavailable in some environments, and, as a result, HIP-printf does not work in those environments. Users may see the following error from runtime (with AMD_LOG_LEVEL 1 and above):

    Pcie atomics not enabled, hostcall not supported

Workaround

The ROCm 5.7 release introduces an alternative to the current hostcall-based implementation that leverages an older OpenCL-based printf scheme, which does not rely on hostcalls/PCIe atomics.

Note: This option is less robust than hostcall-based implementation and is intended to be a workaround when hostcalls do not work.

The printf variant is now controlled via a new compiler option -mprintf-kind=. This is supported only for HIP programs and takes the following values,

  • “hostcall” – This currently available implementation relies on hostcalls, which require the system to support PCIe atomics. It is the default scheme.

  • “buffered” – This implementation leverages the older printf scheme used by OpenCL; it relies on a memory buffer where printf arguments are stored during the kernel execution, and then the runtime handles the actual printing once the kernel finishes execution.

NOTE: With the new workaround:

  • The printf buffer is fixed size and non-circular. After the buffer is filled, calls to printf will not result in additional output.

  • The printf call returns either 0 (on success) or -1 (on failure, due to full buffer), unlike the hostcall scheme that returns the number of characters printed.

Beta release of LLVM AddressSanitizer (ASan) with the GPU#

The ROCm 5.7 release introduces the beta release of LLVM AddressSanitizer (ASan) with the GPU. The LLVM ASan provides a process that allows developers to detect runtime addressing errors in applications and libraries. The detection is achieved using a combination of compiler-added instrumentation and runtime techniques, including function interception and replacement.

Until now, the LLVM ASan process was only available for traditional purely CPU applications. However, ROCm has extended this mechanism to additionally allow the detection of some addressing errors on the GPU in heterogeneous applications. Ideally, developers should treat heterogeneous HIP and OpenMP applications like pure CPU applications. However, this simplicity has not been achieved yet.

Refer to the documentation on LLVM ASan with the GPU at LLVM AddressSanitizer User Guide.

Note: The beta release of LLVM ASan for ROCm is currently tested and validated on Ubuntu 20.04.

Fixed defects#

The following defects are fixed in ROCm v5.7:

  • Test hangs observed in HMM RCCL

  • NoGpuTst test of Catch2 fails with Docker

  • Failures observed with non-HMM HIP directed catch2 tests with XNACK+

  • Multiple test failures and test hangs observed in hip-directed catch2 tests with xnack+

  • Remove hiparray* and make it opaque with hipArray_t

New HIP APIs in this release#

Note

This is a pre-official version (beta) release of the new APIs and may contain unresolved issues.

Memory management HIP APIs#

The new memory management HIP API is as follows:

  • Sets information on the specified pointer [BETA].

    hipError_t hipPointerSetAttribute(const void* value, hipPointer_attribute attribute, hipDeviceptr_t ptr);
Module management HIP APIs#

The new module management HIP APIs are as follows:

  • Launches kernel \(f\) with launch parameters and shared memory on stream with arguments passed to kernelParams, where thread blocks can cooperate and synchronize as they execute.

    hipError_t hipModuleLaunchCooperativeKernel(hipFunction_t f, unsigned int gridDimX, unsigned int gridDimY, unsigned int gridDimZ, unsigned int blockDimX, unsigned int blockDimY, unsigned int blockDimZ, unsigned int sharedMemBytes, hipStream_t stream, void** kernelParams);

  • Launches kernels on multiple devices where thread blocks can cooperate and synchronize as they execute.

    hipError_t hipModuleLaunchCooperativeKernelMultiDevice(hipFunctionLaunchParams* launchParamsList, unsigned int numDevices, unsigned int flags);
HIP Graph Management APIs#

The new HIP Graph Management APIs are as follows:

  • Creates a memory allocation node and adds it to a graph [BETA]

    hipError_t hipGraphAddMemAllocNode(hipGraphNode_t* pGraphNode, hipGraph_t graph, const hipGraphNode_t* pDependencies, size_t numDependencies, hipMemAllocNodeParams* pNodeParams);

  • Return parameters for memory allocation node [BETA]

    hipError_t hipGraphMemAllocNodeGetParams(hipGraphNode_t node, hipMemAllocNodeParams* pNodeParams);

  • Creates a memory free node and adds it to a graph [BETA]

    hipError_t hipGraphAddMemFreeNode(hipGraphNode_t* pGraphNode, hipGraph_t graph, const hipGraphNode_t* pDependencies, size_t numDependencies, void* dev_ptr);

  • Returns parameters for memory free node [BETA].

    hipError_t hipGraphMemFreeNodeGetParams(hipGraphNode_t node, void* dev_ptr);

  • Write a DOT file describing graph structure [BETA].

    hipError_t hipGraphDebugDotPrint(hipGraph_t graph, const char* path, unsigned int flags);

  • Copies attributes from source node to destination node [BETA].

    hipError_t hipGraphKernelNodeCopyAttributes(hipGraphNode_t hSrc, hipGraphNode_t hDst);

  • Enables or disables the specified node in the given graphExec [BETA]

    hipError_t hipGraphNodeSetEnabled(hipGraphExec_t hGraphExec, hipGraphNode_t hNode, unsigned int isEnabled);

  • Query whether a node in the given graphExec is enabled [BETA]

    hipError_t hipGraphNodeGetEnabled(hipGraphExec_t hGraphExec, hipGraphNode_t hNode, unsigned int* isEnabled);
OpenMP enhancements#

This release consists of the following OpenMP enhancements:

  • Additional support for OMPT functions get_device_time and get_record_type.

  • Add support for min/max fast fp atomics on AMD GPUs. Fix the use of the abs function in C device regions.

Deprecations and warnings#

HIP deprecation#

The hipcc and hipconfig Perl scripts are deprecated. In a future release, compiled binaries will be available as hipcc.bin and hipconfig.bin as replacements for the Perl scripts.

Note

There will be a transition period where the Perl scripts and compiled binaries are available before the scripts are removed. There will be no functional difference between the Perl scripts and their compiled binary counterpart. No user action is required. Once these are available, users can optionally switch to hipcc.bin and hipconfig.bin. The hipcc/hipconfig soft link will be assimilated to point from hipcc/hipconfig to the respective compiled binaries as the default option.

Linux file system hierarchy standard for ROCm#

ROCm packages have adopted the Linux foundation file system hierarchy standard in this release to ensure ROCm components follow open source conventions for Linux-based distributions. While moving to a new file system hierarchy, ROCm ensures backward compatibility with its 5.1 version or older file system hierarchy. See below for a detailed explanation of the new file system hierarchy and backward compatibility.

New file system hierarchy#

The following is the new file system hierarchy:4

/opt/rocm-<ver>
    | --bin
      | --All externally exposed Binaries
    | --libexec
        | --<component>
            | -- Component specific private non-ISA executables (architecture independent)
    | --include
        | -- <component>
            | --<header files>
    | --lib
        | --lib<soname>.so -> lib<soname>.so.major -> lib<soname>.so.major.minor.patch
            (public libraries linked with application)
        | --<component> (component specific private library, executable data)
        | --<cmake>
            | --components
                | --<component>.config.cmake
    | --share
        | --html/<component>/*.html
        | --info/<component>/*.[pdf, md, txt]
        | --man
        | --doc
            | --<component>
                | --<licenses>
        | --<component>
            | --<misc files> (arch independent non-executable)
            | --samples

Note

ROCm will not support backward compatibility with the v5.1(old) file system hierarchy in its next major release.

For more information, refer to https://refspecs.linuxfoundation.org/fhs.shtml.

Backward compatibility with older file systems#

ROCm has moved header files and libraries to its new location as indicated in the above structure and included symbolic-link and wrapper header files in its old location for backward compatibility.

Note

ROCm will continue supporting backward compatibility until the next major release.

Wrapper header files#

Wrapper header files are placed in the old location (/opt/rocm-xxx/<component>/include) with a warning message to include files from the new location (/opt/rocm-xxx/include) as shown in the example below:

// Code snippet from hip_runtime.h
#pragma message “This file is deprecated. Use file from include path /opt/rocm-ver/include/ and prefix with hip”.
#include "hip/hip_runtime.h"

The wrapper header files’ backward compatibility deprecation is as follows:

  • #pragma message announcing deprecation – ROCm v5.2 release

  • #pragma message changed to #warning – Future release

  • #warning changed to #error – Future release

  • Backward compatibility wrappers removed – Future release

Library files#

Library files are available in the /opt/rocm-xxx/lib folder. For backward compatibility, the old library location (/opt/rocm-xxx/<component>/lib) has a soft link to the library at the new location.

Example:

$ ls -l /opt/rocm/hip/lib/
total 4
drwxr-xr-x 4 root root 4096 May 12 10:45 cmake
lrwxrwxrwx 1 root root   24 May 10 23:32 libamdhip64.so -> ../../lib/libamdhip64.so
CMake config files#

All CMake configuration files are available in the /opt/rocm-xxx/lib/cmake/<component> folder. For backward compatibility, the old CMake locations (/opt/rocm-xxx/<component>/lib/cmake) consist of a soft link to the new CMake config.

Example:

$ ls -l /opt/rocm/hip/lib/cmake/hip/
total 0
lrwxrwxrwx 1 root root 42 May 10 23:32 hip-config.cmake -> ../../../../lib/cmake/hip/hip-config.cmake

ROCm support for Code Object V3 deprecated#

Support for Code Object v3 is deprecated and will be removed in a future release.

Comgr V3.0 changes#

The following APIs and macros have been marked as deprecated. These are expected to be removed in a future ROCm release and coincides with the release of Comgr v3.0.

API changes#

  • amd_comgr_action_info_set_options()

  • amd_comgr_action_info_get_options()

Actions and data types#

  • AMD_COMGR_ACTION_ADD_DEVICE_LIBRARIES

  • AMD_COMGR_ACTION_COMPILE_SOURCE_TO_FATBIN

For replacements, see the AMD_COMGR_ACTION_INFO_GET/SET_OPTION_LIST APIs, and the AMD_COMGR_ACTION_COMPILE_SOURCE_(WITH_DEVICE_LIBS)_TO_BC macros.

Deprecated environment variables#

The following environment variables are removed in this ROCm release:

  • GPU_MAX_COMMAND_QUEUES

  • GPU_MAX_WORKGROUP_SIZE_2D_X

  • GPU_MAX_WORKGROUP_SIZE_2D_Y

  • GPU_MAX_WORKGROUP_SIZE_3D_X

ROCm 5.4.3#

Deprecations and warnings#

HIP Perl scripts deprecation#

The hipcc and hipconfig Perl scripts are deprecated. In a future release, compiled binaries will be available as hipcc.bin and hipconfig.bin as replacements for the Perl scripts.

Note

There will be a transition period where the Perl scripts and compiled binaries are available before the scripts are removed. There will be no functional difference between the Perl scripts and their compiled binary counterpart. No user action is required. Once these are available, users can optionally switch to hipcc.bin and hipconfig.bin. The hipcc/hipconfig soft link will be assimilated to point from hipcc/hipconfig to the respective compiled binaries as the default option.

Linux file system hierarchy standard for ROCm#

ROCm packages have adopted the Linux foundation file system hierarchy standard in this release to ensure ROCm components follow open source conventions for Linux-based distributions. While moving to a new file system hierarchy, ROCm ensures backward compatibility with its 5.1 version or older file system hierarchy. See below for a detailed explanation of the new file system hierarchy and backward compatibility.

New file system hierarchy#

The following is the new file system hierarchy:4

/opt/rocm-<ver>
    | --bin
      | --All externally exposed Binaries
    | --libexec
        | --<component>
            | -- Component specific private non-ISA executables (architecture independent)
    | --include
        | -- <component>
            | --<header files>
    | --lib
        | --lib<soname>.so -> lib<soname>.so.major -> lib<soname>.so.major.minor.patch
            (public libraries linked with application)
        | --<component> (component specific private library, executable data)
        | --<cmake>
            | --components
                | --<component>.config.cmake
    | --share
        | --html/<component>/*.html
        | --info/<component>/*.[pdf, md, txt]
        | --man
        | --doc
            | --<component>
                | --<licenses>
        | --<component>
            | --<misc files> (arch independent non-executable)
            | --samples

Note

ROCm will not support backward compatibility with the v5.1(old) file system hierarchy in its next major release.

For more information, refer to https://refspecs.linuxfoundation.org/fhs.shtml.

Backward compatibility with older file systems#

ROCm has moved header files and libraries to its new location as indicated in the above structure and included symbolic-link and wrapper header files in its old location for backward compatibility.

Note

ROCm will continue supporting backward compatibility until the next major release.

Wrapper header files#

Wrapper header files are placed in the old location (/opt/rocm-xxx/<component>/include) with a warning message to include files from the new location (/opt/rocm-xxx/include) as shown in the example below:

// Code snippet from hip_runtime.h
#pragma message “This file is deprecated. Use file from include path /opt/rocm-ver/include/ and prefix with hip”.
#include "hip/hip_runtime.h"

The wrapper header files’ backward compatibility deprecation is as follows:

  • #pragma message announcing deprecation – ROCm v5.2 release

  • #pragma message changed to #warning – Future release

  • #warning changed to #error – Future release

  • Backward compatibility wrappers removed – Future release

Library files#

Library files are available in the /opt/rocm-xxx/lib folder. For backward compatibility, the old library location (/opt/rocm-xxx/<component>/lib) has a soft link to the library at the new location.

Example:

$ ls -l /opt/rocm/hip/lib/
total 4
drwxr-xr-x 4 root root 4096 May 12 10:45 cmake
lrwxrwxrwx 1 root root   24 May 10 23:32 libamdhip64.so -> ../../lib/libamdhip64.so
CMake config files#

All CMake configuration files are available in the /opt/rocm-xxx/lib/cmake/<component> folder. For backward compatibility, the old CMake locations (/opt/rocm-xxx/<component>/lib/cmake) consist of a soft link to the new CMake config.

Example:

$ ls -l /opt/rocm/hip/lib/cmake/hip/
total 0
lrwxrwxrwx 1 root root 42 May 10 23:32 hip-config.cmake -> ../../../../lib/cmake/hip/hip-config.cmake

Fixed defects#

Compiler improvements#

In ROCm v5.4.3, improvements to the compiler address errors with the following signatures:

  • “error: unhandled SGPR spill to memory”

  • “cannot scavenge register without an emergency spill slot!”

  • “error: ran out of registers during register allocation”

Known issues#

Compiler option error at runtime#

Some users may encounter a “Cannot find Symbol” error at runtime when using -save-temps. While most -save-temps use cases work correctly, this error may appear occasionally.

This issue is under investigation, and the known workaround is not to use -save-temps when the error appears.

  • The --hipcc-func-supp/--hipcc-no-func-supp options are being deprecated, as the function calls are already supported in production on AMD GPUs.

Known issues#

Under certain circumstances typified by high register pressure, users may encounter a compiler abort with one of the following error messages:

  • error: unhandled SGPR spill to memory

  • cannot scavenge register without an emergency spill slot!

  • error: ran out of registers during register allocation

This is a known issue and will be fixed in a future release.

ROCm 5.4.0#

What’s new in this release#

HIP enhancements#

The ROCm v5.4 release consists of the following HIP enhancements:

Support for wall_clock64#

A new timer function wall_clock64() is supported, which returns wall clock count at a constant frequency on the device.

long long int wall_clock64();

It returns wall clock count at a constant frequency on the device, which can be queried via HIP API with the hipDeviceAttributeWallClockRate attribute of the device in the HIP application code.

Example:

int wallClkRate = 0; //in kilohertz
+HIPCHECK(hipDeviceGetAttribute(&wallClkRate, hipDeviceAttributeWallClockRate, deviceId));

Where hipDeviceAttributeWallClockRate is a device attribute.

Note

The wall clock frequency is a per-device attribute.

New registry added for GPU_MAX_HW_QUEUES#

The GPU_MAX_HW_QUEUES registry defines the maximum number of independent hardware queues allocated per process per device.

The environment variable controls how many independent hardware queues HIP runtime can create per process, per device. If the application allocates more HIP streams than this number, then the HIP runtime reuses the same hardware queues for the new streams in a round-robin manner.

Note

This maximum number does not apply to hardware queues created for CU-masked HIP streams or cooperative queues for HIP Cooperative Groups (there is only one queue per device).

For more details, refer to the HIP Programming Guide.

New HIP APIs in this release#

The following new HIP APIs are available in the ROCm v5.4 release.

Note

This is a pre-official version (beta) release of the new APIs.

Error handling#
hipError_t hipDrvGetErrorName(hipError_t hipError, const char** errorString);

This returns HIP errors in the text string format.

hipError_t hipDrvGetErrorString(hipError_t hipError, const char** errorString);

This returns text string messages with more details about the error.

For more information, refer to the HIP API Guide.

HIP tests source separation#

With ROCm v5.4, a separate GitHub project is created at

ROCm-Developer-Tools/hip-tests

This contains HIP catch2 tests and samples, and new tests will continue to develop.

In future ROCm releases, catch2 tests and samples will be removed from the HIP project.

OpenMP enhancements#

This release consists of the following OpenMP enhancements:

  • Enable new device RTL in libomptarget as default.

  • New flag -fopenmp-target-fast to imply -fopenmp-target-ignore-env-vars -fopenmp-assume-no-thread-state -fopenmp-assume-no-nested-parallelism.

  • Support for the collapse clause and non-unit stride in cases where the no-loop specialized kernel is generated.

  • Initial implementation of optimized cross-team sum reduction for float and double type scalars.

  • Pool-based optimization in the OpenMP runtime to reduce locking during data transfer.

Deprecations and warnings#

HIP Perl scripts deprecation#

The hipcc and hipconfig Perl scripts are deprecated. In a future release, compiled binaries will be available as hipcc.bin and hipconfig.bin as replacements for the Perl scripts.

Note

There will be a transition period where the Perl scripts and compiled binaries are available before the scripts are removed.

Note

ROCm will not support backward compatibility with the v5.1(old) file system hierarchy in its next major release.

For more information, refer to https://refspecs.linuxfoundation.org/fhs.shtml.

Backward compatibility with older file systems#

ROCm has moved header files and libraries to its new location as indicated in the above structure and included symbolic-link and wrapper header files in its old location for backward compatibility.

Note

ROCm will continue supporting backward compatibility until the next major release.

Wrapper header files#

Wrapper header files are placed in the old location (/opt/rocm-xxx/<component>/include) with a warning message to include files from the new location (/opt/rocm-xxx/include) as shown in the example below:

// Code snippet from hip_runtime.h
#pragma message “This file is deprecated. Use file from include path /opt/rocm-ver/include/ and prefix with hip”.
#include "hip/hip_runtime.h"

The wrapper header files’ backward compatibility deprecation is as follows:

  • #pragma message announcing deprecation – ROCm v5.2 release

  • #pragma message changed to #warning – Future release

  • #warning changed to #error – Future release

  • Backward compatibility wrappers removed – Future release

Library files#

Library files are available in the /opt/rocm-xxx/lib folder. For backward compatibility, the old library location (/opt/rocm-xxx/<component>/lib) has a soft link to the library at the new location.

Example:

$ ls -l /opt/rocm/hip/lib/
total 4
drwxr-xr-x 4 root root 4096 May 12 10:45 cmake
lrwxrwxrwx 1 root root   24 May 10 23:32 libamdhip64.so -> ../../lib/libamdhip64.so
CMake config files#

All CMake configuration files are available in the /opt/rocm-xxx/lib/cmake/<component> folder. For backward compatibility, the old CMake locations (/opt/rocm-xxx/<component>/lib/cmake) consist of a soft link to the new CMake config.

Example:

$ ls -l /opt/rocm/hip/lib/cmake/hip/
total 0
lrwxrwxrwx 1 root root 42 May 10 23:32 hip-config.cmake -> ../../../../lib/cmake/hip/hip-config.cmake

Fixed defects#

The following defects are fixed in this release.

These defects were identified and documented as known issues in previous ROCm releases and are fixed in this release.

Memory allocated using hipHostMalloc() with flags didn’t exhibit fine-grain behavior#

Issue#

The test was incorrectly using the hipDeviceAttributePageableMemoryAccess device attribute to determine coherent support.

Fix#

hipHostMalloc() allocates memory with fine-grained access by default when the environment variable HIP_HOST_COHERENT=1 is used.

For more information, refer to HIP Runtime API Reference.

SoftHang with hipStreamWithCUMask test on AMD Instinct™#

Issue#

On GFX10 GPUs, kernel execution hangs when it is launched on streams created using hipStreamWithCUMask.

Fix#

On GFX10 GPUs, each workgroup processor encompasses two compute units, and the compute units must be enabled as a pair. The hipStreamWithCUMask API unit test cases are updated to set compute unit mask (cuMask) in pairs for GFX10 GPUs.

ROCm tools GPU IDs#

The HIP language device IDs are not the same as the GPU IDs reported by the tools. GPU IDs are globally unique and guaranteed to be consistent across APIs and processes.

GPU IDs reported by ROCTracer and ROCProfiler or ROCm Tools are HSA Driver Node ID of that GPU, as it is a unique ID for that device in that particular node.

  • CUB backend references CUB and thrust version 1.17.1.

hipFFT 1.0.10#

hipFFT 1.0.10 for ROCm 5.4.0

Added#

  • Added hipfftExtPlanScaleFactor API to efficiently multiply each output element of a FFT by a given scaling factor. Result scaling must be supported in the backend FFT library.

rocALUTION 2.1.3 for ROCm 5.4.0

Added#

  • Added build support for Navi31 and Navi33

  • Added support for non-squared global matrices

Improved#

  • Fixed a memory leak in MatrixMult on HIP backend

  • Global structures can now be used with a single process

Changed#

  • Switched GTest death test style to ‘threadsafe’

  • GlobalVector::GetGhostSize() is deprecated and will be removed

  • ParallelManager::GetGlobalSize(), ParallelManager::GetLocalSize(), ParallelManager::SetGlobalSize() and ParallelManager::SetLocalSize() are deprecated and will be removed

rocBLAS 2.46.0#

rocBLAS 2.46.0 for ROCm 5.4.0

Added#

  • client smoke test dataset added for quick validation using command rocblas-test –yaml rocblas_smoke.yaml

  • Added stream order device memory allocation as a non-default beta option.

Optimized#

  • Improved trsm performance for small sizes by using a substitution method technique

  • Improved syr2k and her2k performance significantly by using a block-recursive algorithm

Changed#

  • Level 2, Level 1, and Extension functions: argument checking when the handle is set to rocblas_pointer_mode_host now returns the status of rocblas_status_invalid_pointer only for pointers that must be dereferenced based on the alpha and beta argument values. With handle mode rocblas_pointer_mode_device only pointers that are always dereferenced regardless of alpha and beta values are checked and so may lead to a return status of rocblas_status_invalid_pointer. This improves consistency with legacy BLAS behaviour.

  • Add variable to turn on/off ieee16/ieee32 tests for mixed precision gemm

  • Allow hipBLAS to select int8 datatype

Added#

  • Added rocfft_plan_description_set_scale_factor API to efficiently multiply each output element of a FFT by a given scaling factor.

  • Created a rocfft_kernel_cache.db file next to the installed library. SBCC kernels are moved to this file when built with the library, and are runtime-compiled for new GPU architectures.

  • Added gfx1100 and gfx1102 to default AMDGPU_TARGETS.

Changed#

  • Moved runtime compilation cache to in-memory by default. A default on-disk cache can encounter contention problems on multi-node clusters with a shared filesystem. rocFFT can still be told to use an on-disk cache by setting the ROCFFT_RTC_CACHE_PATH environment variable.

rocPRIM 2.12.0#

rocPRIM 2.12.0 for ROCm 5.4.0

Changed#

  • device_partition, device_unique, and device_reduce_by_key now support problem sizes larger than 2^32 items.

Removed#

  • block_sort::sort() overload for keys and values with a dynamic size. This overload was documented but the implementation is missing. To avoid further confusion the documentation is removed until a decision is made on implementing the function.

Fixed#

  • Fixed the compilation failure in device_merge if the two key iterators don’t match.

rocRAND 2.10.16#

rocRAND 2.10.16 for ROCm 5.4.0

Added#

  • LFSR113 pseudorandom number generator based on L’Ecuyer, 1999, “Tables of maximally equidistributed combined LFSR generators”.

  • SCRAMBLED_SOBOL32 and SCRAMBLED_SOBOL64 quasirandom number generators. The Scrambled Sobol sequences are generated by scrambling the output of a Sobol sequence.

Changed#

  • The mrg_&lt;distribution&gt;_distribution structures, which provided numbers based on MRG32K3A, are now replaced by mrg_engine_&lt;distribution&gt;_distribution, where &lt;distribution&gt; is log_normal, normal, poisson, or uniform. These structures provide numbers for MRG31K3P (with template type rocrand_state_mrg31k3p) and MRG32K3A (with template type rocrand_state_mrg32k3a).

Fixed#

  • Sobol64 now returns 64 bits random numbers, instead of 32 bits random numbers. As a result, the performance of this generator has regressed.

  • Fixed a bug that prevented compiling code in C++ mode (with a host compiler) when it included the rocRAND headers on Windows.

rocSOLVER 3.20.0#

rocSOLVER 3.20.0 for ROCm 5.4.0

Deprecations and warnings#

HIP Perl scripts deprecation#

The hipcc and hipconfig Perl scripts are deprecated. In a future release, compiled binaries will be available as hipcc.bin and hipconfig.bin as replacements for the Perl scripts.

Note

There will be a transition period where the Perl scripts and compiled binaries are available before the scripts are removed. There will be no functional difference between the Perl scripts and their compiled binary counterpart. No user action is required. Once these are available, users can optionally switch to hipcc.bin and hipconfig.bin. The hipcc/hipconfig soft link will be assimilated to point from hipcc/hipconfig to the respective compiled binaries as the default option.

Linux file system hierarchy standard for ROCm#

ROCm packages have adopted the Linux foundation file system hierarchy standard in this release to ensure ROCm components follow open source conventions for Linux-based distributions. While moving to a new file system hierarchy, ROCm ensures backward compatibility with its 5.1 version or older file system hierarchy. See below for a detailed explanation of the new file system hierarchy and backward compatibility.

New file system hierarchy#

The following is the new file system hierarchy:

/opt/rocm-<ver>
    | --bin
      | --All externally exposed Binaries
    | --libexec
        | --<component>
            | -- Component specific private non-ISA executables (architecture independent)
    | --include
        | -- <component>
            | --<header files>
    | --lib
        | --lib<soname>.so -> lib<soname>.so.major -> lib<soname>.so.major.minor.patch
            (public libraries linked with application)
        | --<component> (component specific private library, executable data)
        | --<cmake>
            | --components
                | --<component>.config.cmake
    | --share
        | --html/<component>/*.html
        | --info/<component>/*.[pdf, md, txt]
        | --man
        | --doc
            | --<component>
                | --<licenses>
        | --<component>
            | --<misc files> (arch independent non-executable)
            | --samples

Note

ROCm will not support backward compatibility with the v5.1(old) file system hierarchy in its next major release.

For more information, refer to https://refspecs.linuxfoundation.org/fhs.shtml.

Backward compatibility with older file systems#

ROCm has moved header files and libraries to its new location as indicated in the above structure and included symbolic-link and wrapper header files in its old location for backward compatibility.

Note

ROCm will continue supporting backward compatibility until the next major release.

Wrapper header files#

Wrapper header files are placed in the old location (/opt/rocm-xxx/<component>/include) with a warning message to include files from the new location (/opt/rocm-xxx/include) as shown in the example below:

// Code snippet from hip_runtime.h
#pragma message “This file is deprecated. Use file from include path /opt/rocm-ver/include/ and prefix with hip”.
#include "hip/hip_runtime.h"

The wrapper header files’ backward compatibility deprecation is as follows:

  • #pragma message announcing deprecation – ROCm v5.2 release

  • #pragma message changed to #warning – Future release

  • #warning changed to #error – Future release

  • Backward compatibility wrappers removed – Future release

Library files#

Library files are available in the /opt/rocm-xxx/lib folder. For backward compatibility, the old library location (/opt/rocm-xxx/<component>/lib) has a soft link to the library at the new location.

Example:

$ ls -l /opt/rocm/hip/lib/
total 4
drwxr-xr-x 4 root root 4096 May 12 10:45 cmake
lrwxrwxrwx 1 root root   24 May 10 23:32 libamdhip64.so -> ../../lib/libamdhip64.so
CMake config files#

All CMake configuration files are available in the /opt/rocm-xxx/lib/cmake/<component> folder. For backward compatibility, the old CMake locations (/opt/rocm-xxx/<component>/lib/cmake) consist of a soft link to the new CMake config.

Example:

$ ls -l /opt/rocm/hip/lib/cmake/hip/
total 0
lrwxrwxrwx 1 root root 42 May 10 23:32 hip-config.cmake -> ../../../../lib/cmake/hip/hip-config.cmake

Fixed defects#

The following defects are fixed in this release.

These defects were identified and documented as known issues in previous ROCm releases and are fixed in the ROCm v5.3 release.

Kernel produces incorrect results with ROCm 5.2#

User code did not initialize certain data constructs, leading to a correctness issue. A strict reading of the C++ standard suggests that failing to initialize these data constructs is undefined behavior. However, a special case was added for a specific compiler builtin to handle the uninitialized data in a defined manner.

The compiler fix consists of the following patches:

  • A new noundef attribute is added. This attribute denotes when a function call argument or return val may never contain uninitialized bits. For more information, see https://reviews.llvm.org/D81678

  • The application of this attribute was refined such that it was not added to a specific compiler builtin where the compiler knows that inactive lanes do not impact program execution.

For more information, see RadeonOpenCompute/llvm-project.

Known issues#

This section consists of known issues in this release.

Issue with OpenMP-extras package upgrade#

The openmp-extras package has been split into runtime (openmp-extras-runtime) and dev (openmp-extras-devel) packages. This change has broken the upgrade support for the openmp-extras package in RHEL/SLES. An available workaround in RHEL is to use the following command for upgrades:

sudo yum upgrade rocm-language-runtime --allowerasing

An available workaround in SLES is to use the following command for upgrades:

zypper update --force-resolution <meta-package>

AMD Instinct™ MI200 SRIOV virtualization issue#

There is a known issue in this ROCm v5.3 release with all AMD Instinct™ MI200 devices running within a virtual function (VF) under SRIOV virtualization. This issue will likely impact the functionality of SRIOV-based workloads, but does not impact Discrete Device Assignment (DDA) or Bare Metal.

Until a fix is provided, users should rely on ROCm v5.2.3 to support their SRIOV workloads.

System crash when IMMOU is enabled#

If input-output memory management unit (IOMMU) is enabled in SBIOS and ROCm is installed, the system may report the following failure or errors when running workloads such as bandwidth test, clinfo, and HelloWord.cl and cause a system crash.

  • IO PAGE FAULT

  • IRQ remapping does not support X2APIC mode

  • NMI error

Workaround: To avoid the system crash, add amd_iommu=on iommu=pt as the kernel bootparam, as indicated in the warning message.

  • herkx performance improvements for all sizes and data types using block-recursive algorithm.

  • syrk/herk performance improvements by utilising optimised syrkx/herkx code.

Changed#

  • Unifying library logic file names: affects HBH (->HHS_BH), BBH (->BBS_BH), 4xi8BH (->4xi8II_BH). All HPA types are using the new naming convention now.

  • Level 3 function argument checking when the handle is set to rocblas_pointer_mode_host now returns the status of rocblas_status_invalid_pointer only for pointers that must be dereferenced based on the alpha and beta argument values. With handle mode rocblas_pointer_mode_device only pointers that are always dereferenced regardless of alpha and beta values are checked and so may lead to a return status of rocblas_status_invalid_pointer. This improves consistency with legacy BLAS behaviour.

  • Level 1, 2, and 3 function argument checking for enums is now more rigorously matching legacy BLAS so returns rocblas_status_invalid_value if arguments do not match the accepted subset.

Fixed#

  • Improved logic to #include <filesystem> vs <experimental/filesystem>.

  • install.sh -s option to build rocblas as a static library.

  • dot function now sets the device results asynchronously for N <= 0

Deprecated#

  • is_complex helper is now deprecated. Use rocblas_is_complex instead.

  • The enum truncate_t and the value truncate is now deprecated and will removed from the ROCm release 6.0. It is replaced by rocblas_truncate_t and rocblas_truncate, respectively. The new enum rocblas_truncate_t and the value rocblas_truncate could be used from this ROCm release for an easy transition.

Removed#

  • install.sh options –hip-clang , –no-hip-clang, –merge-files, –no-merge-files are removed.

rocFFT 1.0.18#

rocFFT 1.0.18 for ROCm 5.3.0

  • Improved performance of the Bluestein algorithm.

  • Optimized sbcc-168 and 100 by using half-lds.

Fixed#

  • Fixed occasional failures to parallelize runtime compilation of kernels. Failures would be retried serially and ultimately succeed, but this would take extra time.

  • Fixed failures of some R2C 3D transforms that use the unsupported TILE_UNALGNED SBRC kernels. An example is 98^3 R2C out-of-place.

  • Fixed bugs in SBRC_ERC type.

rocRAND 2.10.15 for ROCm 5.3.0

Changed#

  • Increased number of warmup iterations for rocrand_benchmark_generate from 5 to 15 to eliminate corner cases that would generate artificially high benchmark scores.

Removed#

  • Removed dependency on cblas from the rocsolver test and benchmark clients.

Fixed#

Support for Ubuntu 18.04 ends in this release. Future releases of ROCm will not provide prebuilt packages for Ubuntu 18.04. HIP and Other Runtimes

HIP Runtime#

Fixes#

  • A bug was discovered in the HIP graph capture implementation in the ROCm v5.2.0 release. If the same kernel is called twice (with different argument values) in a graph capture, the implementation only kept the argument values for the second kernel call.

What’s new in this release#

HIP enhancements#

The ROCm v5.2 release consists of the following HIP enhancements:

HIP installation guide updates#

The HIP Installation Guide is updated to include building HIP tests from source on the AMD and NVIDIA platforms.

For more details, refer to the HIP Installation Guide v5.2.

Support for device-side malloc on HIP-Clang#

HIP-Clang now supports device-side malloc. This implementation does not require the use of hipDeviceSetLimit(hipLimitMallocHeapSize,value) nor respect any setting. The heap is fully dynamic and can grow until the available free memory on the device is consumed.

The test codes at the following link show how to implement applications using malloc and free functions in device kernels:

Planned HIP changes in future releases#

Changes to hipDeviceProp_t, HIPMEMCPY_3D, and hipArray structures (and related HIP APIs) are planned in the next major release. These changes may impact backward compatibility.

Refer to the Release Notes document in subsequent releases for more information. ROCm Math and Communication Libraries

In this release, ROCm Math and Communication Libraries consist of the following enhancements and fixes: New rocWMMA for Matrix Multiplication and Accumulation Operations Acceleration

This release introduces a new ROCm C++ library for accelerating mixed-precision matrix multiplication and accumulation (MFMA) operations leveraging specialized GPU matrix cores. rocWMMA provides a C++ API to facilitate breaking down matrix multiply accumulate problems into fragments and using them in block-wise operations that are distributed in parallel across GPU wavefronts. The API is a header library of GPU device code, meaning matrix core acceleration may be compiled directly into your kernel device code. This can benefit from compiler optimization in the generation of kernel assembly and does not incur additional overhead costs of linking to external runtime libraries or having to launch separate kernels.

rocWMMA is released as a header library and includes test and sample projects to validate and illustrate example usages of the C++ API. GEMM matrix multiplication is used as primary validation given the heavy precedent for the library. However, the usage portfolio is growing significantly and demonstrates different ways rocWMMA may be consumed.

For more information, refer to Communication Libraries

OpenMP enhancements in this release#

OMPT target support#

The OpenMP runtime in ROCm implements a subset of the OMPT device APIs, as described in the OpenMP specification document. These are APIs that allow first-party tools to examine the profile and traces for kernels that execute on a device. A tool may register callbacks for data transfer and kernel dispatch entry points. A tool may use APIs to start and stop tracing for device-related activities such as data transfer and kernel dispatch timings and associated metadata. If device tracing is enabled, trace records for device activities are collected during program execution and returned to the tool using the APIs described in the specification.

Following is an example demonstrating how a tool would use the OMPT target APIs supported. The README in /opt/rocm/llvm/examples/tools/ompt outlines the steps to follow, and you can run the provided example as indicated below:

cd /opt/rocm/llvm/examples/tools/ompt/veccopy-ompt-target-tracing
make run

The file veccopy-ompt-target-tracing.c simulates how a tool would initiate device activity tracing. The file callbacks.h shows the callbacks that may be registered and implemented by the tool.

Deprecations and warnings#

Linux file system hierarchy standard for ROCm#

ROCm packages have adopted the Linux foundation file system hierarchy standard in this release to ensure ROCm components follow open source conventions for Linux-based distributions. While moving to a new file system hierarchy, ROCm ensures backward compatibility with its 5.1 version or older file system hierarchy. See below for a detailed explanation of the new file system hierarchy and backward compatibility.

New file system hierarchy#

The following is the new file system hierarchy:

/opt/rocm-<ver>
    | --bin
      | --All externally exposed Binaries
    | --libexec
        | --<component>
            | -- Component specific private non-ISA executables (architecture independent)
    | --include
        | -- <component>

Note

ROCm will not support backward compatibility with the v5.1(old) file system hierarchy in its next major release.

For more information, refer to https://refspecs.linuxfoundation.org/fhs.shtml.

Backward compatibility with older file systems#

ROCm has moved header files and libraries to its new location as indicated in the above structure and included symbolic-link and wrapper header files in its old location for backward compatibility.

Note

ROCm will continue supporting backward compatibility until the next major release.

Wrapper header files#

Wrapper header files are placed in the old location (/opt/rocm-xxx/<component>/include) with a warning message to include files from the new location (/opt/rocm-xxx/include) as shown in the example below:

// Code snippet from hip_runtime.h
#pragma message “This file is deprecated. Use file from include path /opt/rocm-ver/include/ and prefix with hip”.
#include "hip/hip_runtime.h"

The wrapper header files’ backward compatibility deprecation is as follows:

  • #pragma message announcing deprecation – ROCm v5.2 release

  • #pragma message changed to #warning – Future release

  • #warning changed to #error – Future release

  • Backward compatibility wrappers removed – Future release

Library files#

Library files are available in the /opt/rocm-xxx/lib folder. For backward compatibility, the old library location (/opt/rocm-xxx/<component>/lib) has a soft link to the library at the new location.

Example:

$ ls -l /opt/rocm/hip/lib/
total 4
drwxr-xr-x 4 root root 4096 May 12 10:45 cmake
lrwxrwxrwx 1 root root   24 May 10 23:32 libamdhip64.so -> ../../lib/libamdhip64.so
CMake config files#

All CMake configuration files are available in the /opt/rocm-xxx/lib/cmake/<component> folder. For backward compatibility, the old CMake locations (/opt/rocm-xxx/<component>/lib/cmake) consist of a soft link to the new CMake config.

Example:

$ ls -l /opt/rocm/hip/lib/cmake/hip/
total 0
lrwxrwxrwx 1 root root 42 May 10 23:32 hip-config.cmake -> ../../../../lib/cmake/hip/hip-config.cmake

Planned deprecation of hip-rocclr and hip-base packages#

In the ROCm v5.2 release, hip-rocclr and hip-base packages (Debian and RPM) are planned for deprecation and will be removed in a future release. hip-runtime-amd and hip-dev(el) will replace these packages respectively. Users of hip-rocclr must install two packages, hip-runtime-amd and hip-dev, to get the same set of packages installed by hip-rocclr previously.

Currently, both package names hip-rocclr (or) hip-runtime-amd and hip-base (or) hip-dev(el) are supported. Deprecation of Integrated HIP Directed Tests

The integrated HIP directed tests, which are currently built by default, are deprecated in this release. The default building and execution support through CMake will be removed in future release.

Known issues#

This section consists of known issues in this release.

Compiler error on gfx1030 when compiling at -O0#

Issue#

A compiler error occurs when using -O0 flag to compile code for gfx1030 that calls atomicAddNoRet, which is defined in amd_hip_atomic.h. The compiler generates an illegal instruction for gfx1030.

Workaround#

The workaround is not to use the -O0 flag for this case. For higher optimization levels, the compiler does not generate an invalid instruction.

System freeze observed during CUDA memtest checkpoint#

Issue#

Checkpoint/Restore in Userspace (CRIU) requires 20 MB of VRAM approximately to checkpoint and restore. The CRIU process may freeze if the maximum amount of available VRAM is allocated to checkpoint applications.

Workaround#

To use CRIU to checkpoint and restore your application, limit the amount of VRAM the application uses to ensure at least 20 MB is available.

HPC test fails with the “HSA_STATUS_ERROR_MEMORY_FAULT” error#

Issue#

The compiler may incorrectly compile a program that uses the __shfl_sync(mask, value, srcLane) function when the “value” parameter to the function is undefined along some path to the function. For most functions, uninitialized inputs cause undefined behavior, but the definition for __shfl_sync should allow for undefined values.

Workaround#

The workaround is to initialize the parameters to __shfl_sync.

Note

When the -Wall compilation flag is used, the compiler generates a warning indicating the variable is initialized along some path.

Example:

double res = 0.0; // Initialize the input to __shfl_sync.
if (lane == 0) {
  res = <some expression>
}
res = __shfl_sync(mask, res, 0);

Kernel produces incorrect result#

Issue#

In recent changes to Clang, insertion of the noundef attribute to all the function arguments has been enabled by default.

In the HIP kernel, variable var in shfl_sync may not be initialized, so LLVM IR treats it as undef.

So, the function argument that is potentially undef (because it is not intialized) has always been assumed to be noundef by LLVM IR (since Clang has inserted noundef attribute). This leads to ambiguous kernel execution.

Workaround#

  • Skip adding noundef attribute to functions tagged with convergent attribute. Refer to https://reviews.llvm.org/D124158 for more information.

  • Introduce shuffle attribute and add it to __shfl like APIs at hip headers. Clang can skip adding noundef attribute, if it finds that argument is tagged with shuffle attribute. Refer to https://reviews.llvm.org/D125378 for more information.

  • Introduce clang builtin for __shfl to identify it and skip adding noundef attribute.

  • Introduce __builtin_freeze to use on the relevant arguments in library wrappers. The library/header need to insert freezes on the relevant inputs.

Issue with applications triggering oversubscription#

There is a known issue with applications that trigger oversubscription. A hardware hang occurs when ROCgdb is used on AMD Instinct™ MI50 and MI100 systems.

This issue is under investigation and will be fixed in a future release.

What’s new in this release#

HIP enhancements#

The ROCm v5.1 release consists of the following HIP enhancements.

HIP installation guide updates#

The HIP Installation Guide is updated to include installation and building HIP from source on the AMD and NVIDIA platforms.

Refer to the HIP Installation Guide v5.1 for more details.

Support for HIP graph#

ROCm v5.1 extends support for HIP Graph.

Planned changes for HIP in future releases#
Separation of hiprtc (libhiprtc) library from hip runtime (amdhip64)#

On ROCm/Linux, to maintain backward compatibility, the hipruntime library (amdhip64) will continue to include hiprtc symbols in future releases. The backward compatible support may be discontinued by removing hiprtc symbols from the hipruntime library (amdhip64) in the next major release.

hipDeviceProp_t structure enhancements#

Changes to the hipDeviceProp_t structure in the next major release may result in backward incompatibility. More details on these changes will be provided in subsequent releases.

ROCDebugger enhancements#

Multi-language source-level debugger#

The compiler now generates a source-level variable and function argument debug information.

The accuracy is guaranteed if the compiler options -g -O0 are used and apply only to HIP.

This enhancement enables ROCDebugger users to interact with the HIP source-level variables and function arguments.

Note

The newly-suggested compiler -g option must be used instead of the previously-suggested -ggdb option. Although the effect of these two options is currently equivalent, this is not guaranteed for the future and might get changed by the upstream LLVM community.

Machine interface lanes support#

ROCDebugger Machine Interface (MI) extends support to lanes. The following enhancements are made:

  • Added a new -lane-info command, listing the current thread’s lanes.

  • The -thread-select command now supports a lane switch to switch to a specific lane of a thread:

    -thread-select -l LANE THREAD

  • The =thread-selected notification gained a lane-id attribute. This enables the frontend to know which lane of the thread was selected.

  • The *stopped asynchronous record gained lane-id and hit-lanes attributes. The former indicates which lane is selected, and the latter indicates which lanes explain the stop.

  • MI commands now accept a global –lane option, similar to the global –thread and –frame options.

  • MI varobjs are now lane-aware.

For more information, refer to the ROC Debugger User Guide at ROCgdb.

Enhanced - clone-inferior command#

The clone-inferior command now ensures that the TTY, CMD, ARGS, and AMDGPU PRECISE-MEMORY settings are copied from the original inferior to the new one. All modifications to the environment variables done using the ‘set environment’ or ‘unset environment’ commands are also copied to the new inferior.

MIOpen support for RDNA GPUs#

This release includes support for AMD Radeon™ Pro W6800, in addition to other bug fixes and performance improvements as listed below:

  • MIOpen now supports RDNA GPUs!! (via MIOpen PRs 973, 780, 764, 740, 739, 677, 660, 653, 493, 498)

  • Fixed a correctness issue with ImplicitGemm algorithm

  • Updated the performance data for new kernel versions

  • Improved MIOpen build time by splitting large kernel header files

  • Fixed an issue in reduction kernels for padded tensors

  • Various other bug fixes and performance improvements

For more information, see Documentation.

Checkpoint restore support with CRIU#

The new Checkpoint Restore in Userspace (CRIU) functionality is implemented to support AMD GPU and ROCm applications.

CRIU is a userspace tool to Checkpoint and Restore an application.

CRIU lacked the support for checkpoint restore applications that used device files such as a GPU. With this ROCm release, CRIU is enhanced with a new plugin to support AMD GPUs, which includes:

  • Single and Multi GPU systems (Gfx9)

  • Checkpoint / Restore on a different system

  • Checkpoint / Restore inside a docker container

  • PyTorch

  • TensorFlow

  • Using CRIU Image Streamer

For more information, refer to checkpoint-restore/criu

Note

The CRIU plugin (amdgpu_plugin) is merged upstream with the CRIU repository. The KFD kernel patches are also available upstream with the amd-staging-drm-next branch (public) and the ROCm 5.1 release branch.

Note

This is a Beta release of the Checkpoint and Restore functionality, and some features are not available in this release.

For more information, refer to the following websites:

Fixed defects#

The following defects are fixed in this release.

Driver fails to load after installation#

The issue with the driver failing to load after ROCm installation is now fixed.

The driver installs successfully, and the server reboots with working rocminfo and clinfo.

ROCDebugger fixed defects#

Breakpoints in GPU kernel code before kernel is loaded#

Previously, setting a breakpoint in device code by line number before the device code was loaded into the program resulted in ROCgdb incorrectly moving the breakpoint to the first following line that contains host code.

Now, the breakpoint is left pending. When the GPU kernel gets loaded, the breakpoint resolves to a location in the kernel.

Registers invalidated after write#

Previously, the stale just-written value was presented as a current value.

ROCgdb now invalidates the cached values of registers whose content might differ after being written. For example, registers with read-only bits.

ROCgdb also invalidates all volatile registers when a volatile register is written. For example, writing VCC invalidates the content of STATUS as STATUS.VCCZ may change.

Scheduler-locking and GPU wavefronts#

When scheduler-locking is in effect, new wavefronts created by a resumed thread, CPU, or GPU wavefront, are held in the halt state. For example, the “set scheduler-locking” command.

ROCDebugger fails before completion of kernel execution#

It was possible (although erroneous) for a debugger to load GPU code in memory, send it to the device, start executing a kernel on the device, and dispose of the original code before the kernel had finished execution. If a breakpoint was hit after this point, the debugger failed with an internal error while trying to access the debug information.

This issue is now fixed by ensuring that the debugger keeps a local copy of the original code and debug information.

Known issues#

Random memory access fault errors observed while running math libraries unit tests#

Issue: Random memory access fault issues are observed while running Math libraries unit tests. This issue is encountered in ROCm v5.0, ROCm v5.0.1, and ROCm v5.0.2.

Note, the faults only occur in the SRIOV environment.

Workaround: Use SDMA to update the page table. The Guest set up steps are as follows:

sudo modprobe amdgpu vm_update_mode=0

To verify, use

Guest:

cat /sys/module/amdgpu/parameters/vm_update_mode 0

Where expectation is 0.

CU masking causes application to freeze#

Using CU Masking results in an application freeze or runs exceptionally slowly. This issue is noticed only in the GFX10 suite of products. Note, this issue is observed only in GFX10 suite of products.

This issue is under active investigation at this time.

Failed checkpoint in Docker containers#

A defect with Ubuntu images kernel-5.13-30-generic and kernel-5.13-35-generic with Overlay FS results in incorrect reporting of the mount ID.

This issue with Ubuntu causes CRIU checkpointing to fail in Docker containers.

As a workaround, use an older version of the kernel. For example, Ubuntu 5.11.0-46-generic.

Issue with restoring workloads using cooperative groups feature#

Workloads that use the cooperative groups function to ensure all waves can be resident at the same time may fail to restore correctly. This issue is under investigation and will be fixed in a future release.

Radeon Pro V620 and W6800 workstation GPUs#

No support for ROCDebugger on SRIOV#

ROCDebugger is not supported in the SRIOV environment on any GPU.

This is a known issue and will be fixed in a future release.

Random error messages in ROCm SMI for SR-IOV#

Random error messages are generated by unsupported functions or commands.

This is a known issue and will be fixed in a future release.

ROCm 5.0.2#

Fixed defects#

The following defects are fixed in the ROCm v5.0.2 release.

Issue with hostcall facility in HIP runtime#

In ROCm v5.0, when using the “assert()” call in a HIP kernel, the compiler may sometimes fail to emit kernel metadata related to the hostcall facility, which results in incomplete initialization of the hostcall facility in the HIP runtime. This can cause the HIP kernel to crash when it attempts to execute the “assert()” call.

The root cause was an incorrect check in the compiler to determine whether the hostcall facility is required by the kernel. This is fixed in the ROCm v5.0.2 release.

The resolution includes a compiler change, which emits the required metadata by default, unless the compiler can prove that the hostcall facility is not required by the kernel. This ensures that the “assert()” call never fails.

Note: This fix may lead to breakage in some OpenMP offload use cases, which use print inside a target region and result in an abort in device code. The issue will be fixed in a future release. Compatibility Matrix Updates to the Deep-learning guide

The compatibility matrix in the Deep-learning guide is updated for ROCm v5.0.2.

Deprecations and warnings#

Refactor of HIPCC/HIPCONFIG#

In prior ROCm releases, by default, the hipcc/hipconfig Perl scripts were used to identify and set target compiler options, target platform, compiler, and runtime appropriately.

In ROCm v5.0.1, hipcc.bin and hipconfig.bin have been added as the compiled binary implementations of the hipcc and hipconfig. These new binaries are currently a work-in-progress, considered, and marked as experimental. ROCm plans to fully transition to hipcc.bin and hipconfig.bin in the a future ROCm release. The existing hipcc and hipconfig Perl scripts are renamed to hipcc.pl and hipconfig.pl respectively. New top-level hipcc and hipconfig Perl scripts are created, which can switch between the Perl script or the compiled binary based on the environment variable HIPCC_USE_PERL_SCRIPT.

In ROCm 5.0.1, by default, this environment variable is set to use hipcc and hipconfig through the Perl scripts.

Subsequently, Perl scripts will no longer be available in ROCm in a future release.

What’s new in this release#

HIP enhancements#

The ROCm v5.0 release consists of the following HIP enhancements.

HIP installation guide updates#

The HIP Installation Guide is updated to include building HIP from source on the NVIDIA platform.

Refer to the HIP Installation Guide v5.0 for more details.

Managed memory allocation#

Managed memory, including the __managed__ keyword, is now supported in the HIP combined host/device compilation. Through unified memory allocation, managed memory allows data to be shared and accessible to both the CPU and GPU using a single pointer. The allocation is managed by the AMD GPU driver using the Linux Heterogeneous Memory Management (HMM) mechanism. The user can call managed memory API hipMallocManaged to allocate a large chunk of HMM memory, execute kernels on a device, and fetch data between the host and device as needed.

Note

In a HIP application, it is recommended to do a capability check before calling the managed memory APIs. For example,

int managed_memory = 0;
HIPCHECK(hipDeviceGetAttribute(&managed_memory,
  hipDeviceAttributeManagedMemory,p_gpuDevice));
if (!managed_memory ) {
  printf ("info: managed memory access not supported on the device %d\n Skipped\n", p_gpuDevice);
}
else {
  HIPCHECK(hipSetDevice(p_gpuDevice));
  HIPCHECK(hipMallocManaged(&Hmm, N * sizeof(T)));
. . .
}

Note

The managed memory capability check may not be necessary; however, if HMM is not supported, managed malloc will fall back to using system memory. Other managed memory API calls will, then, have

Refer to the HIP API documentation for more details on managed memory APIs.

For the application, see

ROCm-Developer-Tools/HIP

New environment variable#

The following new environment variable is added in this release:

Environment Variable

Value

Description

HSA_COOP_CU_COUNT

0 or 1 (default is 0)

Some processors support more CUs than can reliably be used in a cooperative dispatch. Setting the environment variable HSA_COOP_CU_COUNT to 1 will cause ROCr to return the correct CU count for cooperative groups through the HSA_AMD_AGENT_INFO_COOPERATIVE_COMPUTE_UNIT_COUNT attribute of hsa_agent_get_info(). Setting HSA_COOP_CU_COUNT to other values, or leaving it unset, will cause ROCr to return the same CU count for the attributes HSA_AMD_AGENT_INFO_COOPERATIVE_COMPUTE_UNIT_COUNT and HSA_AMD_AGENT_INFO_COMPUTE_UNIT_COUNT. Future ROCm releases will make HSA_COOP_CU_COUNT=1 the default.

Breaking changes#

Runtime breaking change#

Re-ordering of the enumerated type in hip_runtime_api.h to better match NV. See below for the difference in enumerated types.

ROCm software will be affected if any of the defined enums listed below are used in the code. Applications built with ROCm v5.0 enumerated types will work with a ROCm 4.5.2 driver. However, an undefined behavior error will occur with a ROCm v4.5.2 application that uses these enumerated types with a ROCm 5.0 runtime.

Known issues#

Incorrect dGPU behavior when using AMDVBFlash tool#

The AMDVBFlash tool, used for flashing the VBIOS image to dGPU, does not communicate with the ROM Controller specifically when the driver is present. This is because the driver, as part of its runtime power management feature, puts the dGPU to a sleep state.

As a workaround, users can run amdgpu.runpm=0, which temporarily disables the runtime power management feature from the driver and dynamically changes some power control-related sysfs files.

Issue with START timestamp in ROCProfiler#

Users may encounter an issue with the enabled timestamp functionality for monitoring one or multiple counters. ROCProfiler outputs the following four timestamps for each kernel:

  • Dispatch

  • Start

  • End

  • Complete

Issue#

This defect is related to the Start timestamp functionality, which incorrectly shows an earlier time than the Dispatch timestamp.

To reproduce the issue,

  1. Enable timing using the –timestamp on flag.

  2. Use the -i option with the input filename that contains the name of the counter(s) to monitor.

  3. Run the program.

  4. Check the output result file.

Current behavior#

BeginNS is lower than DispatchNS, which is incorrect.

Expected behavior#

The correct order is:

Dispatch < Start < End < Complete

Users cannot use ROCProfiler to measure the time spent on each kernel because of the incorrect timestamp with counter collection enabled.

Radeon Pro V620 and W6800 workstation GPUs#

No support for SMI and ROCDebugger on SRIOV#

System Management Interface (SMI) and ROCDebugger are not supported in the SRIOV environment on any GPU. For more information, refer to the Systems Management Interface documentation.

Deprecations and warnings#

ROCm libraries changes – deprecations and deprecation removal#

  • The hipFFT.h header is now provided only by the hipFFT package. Up to ROCm 5.0, users would get hipFFT.h in the rocFFT package too.

  • The GlobalPairwiseAMG class is now entirely removed, users should use the PairwiseAMG class instead.

  • The rocsparse_spmm signature in 5.0 was changed to match that of rocsparse_spmm_ex. In 5.0, rocsparse_spmm_ex is still present, but deprecated. Signature diff for rocsparse_spmm rocsparse_spmm in 5.0

HIP API deprecations and warnings#

Warning - arithmetic operators of HIP complex and vector types#

In this release, arithmetic operators of HIP complex and vector types are deprecated.

  • As alternatives to arithmetic operators of HIP complex types, users can use arithmetic operators of std::complex types.

  • As alternatives to arithmetic operators of HIP vector types, users can use the operators of the native clang vector type associated with the data member of HIP vector types.

During the deprecation, two macros _HIP_ENABLE_COMPLEX_OPERATORS and _HIP_ENABLE_VECTOR_OPERATORS are provided to allow users to conditionally enable arithmetic operators of HIP complex or vector types.

Note, the two macros are mutually exclusive and, by default, set to Off.

The arithmetic operators of HIP complex and vector types will be removed in a future release.

Refer to the HIP API Guide for more information.

Warning - compiler-generated code object version 4 deprecation#

Support for loading compiler-generated code object version 4 will be deprecated in a future release with no release announcement and replaced with code object 5 as the default version.

The current default is code object version 4.

Warning - MIOpenTensile deprecation#

MIOpenTensile will be deprecated in a future release.

  • The block sizes for device merge sorts initial block sort and its merge steps are now separate in its kernel config

    • the block sort step supports multiple items per thread

Changed#

  • size_limit for scan, reduce and transform can now be set in the config struct instead of a parameter

  • Device_scan and device_segmented_scan: inclusive_scan now uses the input-type as accumulator-type, exclusive_scan uses initial-value-type.

    • This particularly changes behaviour of small-size input types with large-size output types (e.g. short input, int output).

    • And low-res input with high-res output (e.g. float input, double output)

  • Revert old Fiji workaround, because they solved the issue at compiler side

  • Update README cmake minimum version number

  • Block sort support multiple items per thread

    • currently only powers of two block sizes, and items per threads are supported and only for full blocks

  • Bumped the minimum required version of CMake to 3.16

Known Issues#

  • Unit tests may soft hang on MI200 when running in hipMallocManaged mode.

  • device_segmented_radix_sort, device_scan unit tests failing for HIP on Windows

  • ReduceEmptyInput cause random faulire with bfloat16

rocRAND 2.10.12#

rocRAND 2.10.12 for ROCm 5.0.0

Changed#

  • No updates or changes for ROCm 5.0.0.

rocSOLVER 3.16.0#

rocSOLVER 3.16.0 for ROCm 5.0.0

Added#

  • Symmetric matrix factorizations:

    • LASYF

    • SYTF2, SYTRF (with batched and strided_batched versions)

  • Added rocsolver_get_version_string_size to help with version string queries

  • Added rocblas_layer_mode_ex and the ability to print kernel calls in the trace and profile logs

  • Expanded batched and strided_batched sample programs.

Optimized#

  • Improved general performance of LU factorization

  • Increased parallelism of specialized kernels when compiling from source, reducing build times on multi-core systems.

Changed#

  • The rocsolver-test client now prints the rocSOLVER version used to run the tests, rather than the version used to build them

  • The rocsolver-bench client now prints the rocSOLVER version used in the benchmark

Fixed#

  • Added missing stdint.h include to rocsolver.h

rocSPARSE 2.0.0#

rocSPARSE 2.0.0 for ROCm 5.0.0

Added#

  • csrmv, coomv, ellmv, hybmv for (conjugate) transposed matrices

  • csrmv for symmetric matrices

Changed#

  • spmm_ex is now deprecated and will be removed in the next major release

Improved#

  • Optimization for gtsv

rocThrust 2.13.0#

rocThrust 2.13.0 for ROCm 5.0.0

Added#

  • Updated to match upstream Thrust 1.13.0

  • Updated to match upstream Thrust 1.14.0

  • Added async scan

Changed#

  • Scan algorithms: inclusive_scan now uses the input-type as accumulator-type, exclusive_scan uses initial-value-type.

    • This particularly changes behaviour of small-size input types with large-size output types (e.g. short input, int output).

    • And low-res input with high-res output (e.g. float input, double output)

Tensile 4.31.0#

Tensile 4.31.0 for ROCm 5.0.0

Added#

  • DirectToLds support (x2/x4)

  • DirectToVgpr support for DGEMM

  • Parameter to control number of files kernels are merged into to better parallelize kernel compilation

  • FP16 alternate implementation for HPA HGEMM on aldebaran

Optimized#

  • Add DGEMM NN custom kernel for HPL on aldebaran

Changed#

  • Update tensile_client executable to std=c++14

Removed#

  • Remove unused old Tensile client code

Fixed#

  • Fix hipErrorInvalidHandle during benchmarks

  • Fix addrVgpr for atomic GSU

  • Fix for Python 3.8: add case for Constant nodeType

  • Fix architecture mapping for gfx1011 and gfx1012

  • Fix PrintSolutionRejectionReason verbiage in KernelWriter.py

  • Fix vgpr alignment problem when enabling flat buffer load
