Applies to Linux and Windows
Atomic operations guarantee that the operation is completed as an indivisible unit, preventing race conditions where simultaneous access to the same memory location could lead to incorrect or undefined behavior.
This document details the various support of atomic read-modify-write (atomicRMW) operations on gfx9, gfx10, gfx11, gfx12, MI100, MI200 and MI300 AMD GPUs. The atomics operation type behavior effected by the memory locations, memory granularity or scope of operations.
Memory locations:
Device memory, i.e. VRAM, the RAM on a discrete GPU device or in framebuffer carveout for APUs. This includes peer-device memory within an Infinity Fabric™ hive.
Host memory: in DRAM associated with the CPU (or peer device memory using PCIe® (PCI Express) peer-to-peer). This can be two sub-types:
Migratable memory: memory that is currently residing in host DRAM, but which can be migrated back to device memory. For example,
hipMallocManaged()or unified memory allocations.Pinned memory: memory that is in host memory and cannot be migrated to the device (not necessarily pinned to a particular physical address, but can’t be moved to device memory).
hipHostMalloc(), for example.
Memory granularity or coherence:
Coarse-grained memory
This memory can be used for device-scope synchronization during the execution of a single GPU kernel. Any system-scope atomics sent to this type of memory will not achieve system-scope coherency and will instead be downgraded to device-scope as per the programming model.
This type of memory only available on AMD GPUs.
Fine-grained memory
This memory can be used for device and system-scope synchronization during the execution of a single GPU kernel.
Scopes of operations:
Device-scope or agent-scope
This atomic should happen atomically from the point of view of every thread within the device that the atomic-executing thread is in.
System-scope
This atomic should happen atomically from the point of view of every thread in all devices and in the CPUs.
Support summary#
AMD Instinct™ accelerators#
MI300
All atomicRMW operations are forwarded out to the Infinity Fabric.
Infinity Fabric supports common integer and bitwise atomics, FP32 atomic add, packed-FP16 atomic add, packed-BF16 atomic add, and FP64 add, min, and max.
In discrete GPUs (dGPUs), if the data is stored in host memory, the atomic will be forwarded from the Infinity Fabric to PCIe.
If the PCIe bus does not support the requested atomic, the GPU’s PCIe controller changes it into a load-op-store sequence. All waves on the chip submitting atomics to that address will stall waiting for the load-op-store. It will seem like atomics to the wave, but the CPU sees it as a non-atomic load-op-store sequence. This downgrades system-scope atomics to device-scope.
MI200
L2 cache and Infinity Fabric both support common integer and bitwise atomics.
L2 cache supports FP32 atomic add, packed-FP16 atomic add, and FP64 add, min, and max.
The Infinity Fabric does not support FP32 atomic add, packed-FP16 atomic add, and FP64 add, min, and max atomics and these commands cannot be sent to the Infinity Fabric.
Coarse-grained memory is marked as cacheable, and atomic operations will be processed in the L2 cache.
Fine-grained memory is marked write-uncacheable through the page tables.
Atomics that hit write-uncached memory are forwarded to the Infinity Fabric.
If the uncached data is stored in host memory on a PCIe system, the atomic will be forwarded from Infinity Fabric to PCIe. Any atomic not supported by the PCIe bus will be a NOP and give incorrect result.
If the uncached data is stored in host memory on an A+A system (system with AMD CPU and AMD GPU connected via Infinity Fabric), the atomic operation will be forwarded to the remote location and will succeed if supported by Infinity Fabric.
If the float atomics access write-uncached memory, they cannot be forwarded to the Infinity Fabric, resulting in a NOP and an incorrect outcome.
MI100
L2 cache and Infinity Fabric both support common integer and bitwise atomics.
L2 cache supports no returns (NoReturn) versions of packed-FP16 and FP32 atomic adds, that cannot return data.
The Infinity Fabric does not support packed-FP16 or FP32 atomic adds, preventing these commands from being transmitted through it.
Coarse-grained memory is marked as cacheable, and atomic operations will be processed in the L2 cache.
Fine-grained memory is marked uncacheable through the page tables.
Atomics that hit uncached memory are forwarded to the Infinity Fabric.
If the uncached data is stored in host memory, the atomic will be forwarded from Infinity Fabric to PCIe. Any atomic not supported by the PCIe bus will be a NOP and give incorrect result.
If an float atomic add hits uncached memory, it cannot be forwarded to the Infinity Fabric so it will NOP and give incorrect result.
AMD gfx generic targets#
gfx9
L2 cache and Infinity Fabric both support common integer and bitwise atomics.
Coarse-grained memory is marked as cacheable, and atomic operations will be processed in the L2 cache.
Fine-grained memory is marked uncacheable through the page tables.
Atomics that hit uncached memory are forwarded to the Infinity Fabric.
In a dGPU: if the uncached data is stored in host memory, the atomic will be forwarded from Infinity Fabric to PCIe. Any atomic not supported by the PCIe bus will be a NOP and.
gfx10
L2 cache and Infinity Fabric both support common integer and bitwise atomics.
Coarse-grained memory is marked as cacheable, and atomic operations will be processed in the L2 cache.
Fine-grained memory is marked uncacheable through the page tables.
Atomics that hit uncached memory are forwarded to the Infinity Fabric.
In a dGPU: if the uncached data is stored in host memory, the atomic will be forwarded from Infinity Fabric to PCIe. Any atomic not supported by the PCIe bus will be a NOP and give incorrect result.
Supports floating-point atomic min/max.
The Infinity Fabric does not support floating-point atomic min/max atomics and these commands cannot be sent to the Infinity Fabric.
If the floating-point atomics hit uncached memory, they cannot be forwarded to the Infinity Fabric, so they will NOP and give incorrect result.
gfx11
L2 cache and Infinity Fabric both support common integer and bitwise atomics.
L2 cache supports FP32 atomic add, min and max.
The Infinity Fabric does not support FP32 atomic add, min and max atomics and these commands cannot be sent to the Infinity Fabric.
Coarse-grained memory is marked as cacheable, and atomic operations will be processed in the L2 cache.
Fine-grained memory is marked uncacheable through the page tables.
Atomics that hit write-uncached memory are forwarded to the Infinity Fabric.
In a dGPU: if the uncached data is stored in host memory, the atomic will be forwarded from Infinity Fabric to PCIe. Any atomic not supported by the PCIe bus will be a NOP and give incorrect result.
If the float atomics hit uncached memory, they cannot be forwarded to the Infinity Fabric, so they will NOP and give incorrect result.
gfx12
L2 cache and Infinity Fabric both support common integer and bitwise atomics.
L2 cache and Infinity Fabric both also support FP32 atomic add, min and max, and packed-FP16 atomic add, and packed-BF16 atomic add.
Coarse-grained memory is marked as cacheable, and atomic operations will be processed in the L2 cache.
Fine-grained device memory is marked uncacheable through the page tables.
Atomics that hit write-uncached memory are forwarded to the Infinity Fabric.
Fine-grained system memory is marked as cacheable through the page tables.
Device-scope atomic operations will process in the L2 cache.
System-scope atomic operations will bypass the L2 cache and be forwarded to the Infinity Fabric.
Atomics that hit write-uncached memory are forwarded to the Infinity Fabric.
In dGPUs, if the data is stored in host memory, the atomic will be forwarded from the Infinity Fabric to PCIe.
If the PCIe bus does not support the requested atomic, the GPU’s PCIe controller changes it into a load-op-store sequence. All waves on the chip submitting atomics to that address will stall waiting for the load-op-store. It will seem like atomics to the wave, but the CPU sees it as a non-atomic load-op-store sequence. This downgrades system-scope atomics to device-scope.
GPUs atomics support#
This section presents a series of tables that show the level of atomic operations support for the different hardware devices described above, and different datatypes, different operations and different scopes.
Hardware atomics support refers to the ability of GPUs to natively perform atomic operations—special low-level operations that ensure data consistency when multiple threads access and modify memory concurrently.
CAS (Compare-and-Swap) atomic support refers to the hardware or software capability to perform an atomic Compare-and-Swap operation.
PCIe atomics are a feature of the PCIe interface that enable atomic operations between devices and hosts across the PCIe bus. For further information, please check How ROCm uses PCIe atomics.
The tables that follow show the correctness of atomics operations on the hardware using the following notations:
✅: Produces the correct answer.
⚠️: Produces the correct answer, but works only at a weaker scope.
❌: The atomics operation fails.
The tables show the different types of atomic operations used by specific devices:
Native: Computes the correct result using a hardware-native atomic instruction.
CAS: Generates the correct result, but the atomic operation is implemented by the compiler for this ISA using a compare-and-swap emulation loop.
✅ NoReturn: Produces the correct correct result but does not precisely conform to the atomic API.
Scope Downgrade: Generates the correct result but operates at a weaker scope than requested. For example, if a user specifies a system-scope atomic, the operation may only function at the device scope.
NOP: The atomic operation is not executed on the target location, and the requesting thread receives back 0 as a return value.
n/a: The atomic type is not supported and cannot be executed on the specific hardware.
The tables selectors or options are the following:
Highest level option:
“HW atomics”, where software attempts to use hardware atomics.
“CAS emulation”, where software attempts to use CAS emulation.
Second-level option:
“No PCIe atomics” means the system does not support PCIe atomics between the accelerator and peer/host-memory.
“PCIe atomics” means the system supports PCIe atomics between the accelerator and peer/host-memory.
The third-level option is the memory granularity of the memory target.
The final option is the scope of atomic access.
