Build HIP from source

Build HIP from source#

Prerequisites#

HIP code can be developed either on AMD ROCm platform using HIP-Clang compiler, or a CUDA platform with nvcc installed. Before building and running HIP, make sure drivers and prebuilt packages are installed properly on the platform.

You also need to install Python 3, which includes the CppHeaderParser package. Install Python 3 using the following command:

apt-get install python3

Check and install CppHeaderParser package using the command:

pip3 install CppHeaderParser

Install ROCm LLVM package using the command:

apt-get install rocm-llvm-dev

Building the HIP runtime#

Set the repository branch using the variable: ROCM_BRANCH. For example, for ROCm 6.1, use:

export ROCM_BRANCH=rocm-6.1.x

AMD

Get HIP source code.

Note

Starting in ROCM 5.6, CLR is a new repository that includes the former ROCclr, HIPAMD and OpenCl repositories. OpenCL provides headers that ROCclr runtime depends on.

Note

Starting in ROCM 6.1, a new repository hipother is added to ROCm, which is branched out from HIP. hipother provides files required to support the HIP back-end implementation on some non-AMD platforms, like NVIDIA.
```
git clone -b "$ROCM_BRANCH" https://github.com/ROCm/clr.git
git clone -b "$ROCM_BRANCH" https://github.com/ROCm/hip.git
```
CLR (Compute Language Runtime) repository includes ROCclr, HIPAMD and OpenCL.

ROCclr (ROCm Compute Language Runtime) is a virtual device interface which is defined on the AMD platform. HIP runtime uses ROCclr to interact with different backends.

HIPAMD provides implementation specifically for HIP on the AMD platform.

OpenCL provides headers that ROCclr runtime currently depends on. hipother provides headers and implementation specifically for non-AMD HIP platforms, like NVIDIA.

Set the environment variables.

export CLR_DIR="$(readlink -f clr)"
export HIP_DIR="$(readlink -f hip)"

Build HIP.
```
cd "$CLR_DIR"
mkdir -p build; cd build
cmake -DHIP_COMMON_DIR=$HIP_DIR -DHIP_PLATFORM=amd -DCMAKE_PREFIX_PATH="/opt/rocm/" -DCMAKE_INSTALL_PREFIX=$PWD/install -DHIP_CATCH_TEST=0 -DCLR_BUILD_HIP=ON -DCLR_BUILD_OCL=OFF ..

make -j$(nproc)
sudo make install
```
Note

Note, if you don’t specify CMAKE_INSTALL_PREFIX, the HIP runtime is installed at <ROCM_PATH>.

By default, release version of HIP is built. If need debug version, you can put the option CMAKE_BUILD_TYPE=Debug in the command line.

Default paths and environment variables:
- HIP is installed into <ROCM_PATH>. This can be overridden by setting the INSTALL_PREFIX as the command option.
- HSA is in <ROCM_PATH>. This can be overridden by setting the HSA_PATH environment variable.
- Clang is in <ROCM_PATH>/llvm/bin. This can be overridden by setting the HIP_CLANG_PATH environment variable.
- The device library is in <ROCM_PATH>/lib. This can be overridden by setting the DEVICE_LIB_PATH environment variable.
- Optionally, you can add <ROCM_PATH>/bin to your PATH, which can make it easier to use the tools.
- Optionally, you can set HIPCC_VERBOSE=7 to output the command line for compilation.
After you run the make install command, HIP is installed to <ROCM_PATH> by default, or $PWD/install/hip while INSTALL_PREFIX is defined.

Generate a profiling header after adding/changing a HIP API.

When you add or change a HIP API, you may need to generate a new hip_prof_str.h header. This header is used by ROCm tools to track HIP APIs, such as rocprofiler and roctracer.

To generate the header after your change, use the hip_prof_gen.py tool located in hipamd/src.

Usage:

`hip_prof_gen.py [-v] <input HIP API .h file> <patched srcs path> <previous output> [<output>]`

Flags:

   * ``-v``: Verbose messages
   * ``-r``: Process source directory recursively
   * ``-t``: API types matching check
   * ``--priv``: Private API check
   * ``-e``: On error exit mode
   * ``-p``: ``HIP_INIT_API`` macro patching mode

Example usage:

hip_prof_gen.py -v -p -t --priv <hip>/include/hip/hip_runtime_api.h \
<hipamd>/src <hipamd>/include/hip/amd_detail/hip_prof_str.h \
<hipamd>/include/hip/amd_detail/hip_prof_str.h.new

NVIDIA

Get the HIP source code.

git clone -b "$ROCM_BRANCH" https://github.com/ROCm/clr.git
git clone -b "$ROCM_BRANCH" https://github.com/ROCm/hip.git
git clone -b "$ROCM_BRANCH" https://github.com/ROCm/hipother.git

Set the environment variables.

export CLR_DIR="$(readlink -f clr)"
export HIP_DIR="$(readlink -f hip)"
export HIP_OTHER="$(readlink -f hipother)"

Build HIP.

cd "$CLR_DIR"
mkdir -p build; cd build
cmake -DHIP_COMMON_DIR=$HIP_DIR -DHIP_PLATFORM=nvidia -DCMAKE_INSTALL_PREFIX=$PWD/install -DHIP_CATCH_TEST=0 -DCLR_BUILD_HIP=ON -DCLR_BUILD_OCL=OFF -DHIPNV_DIR=$HIP_OTHER/hipnv ..
make -j$(nproc)
sudo make install

Note

The HIP runtime is only buildable on Linux.

Build HIP tests#

AMD

Build HIP catch tests.

HIP catch tests are separate from the HIP project and use Catch2.

Get HIP tests source code.

git clone -b "$ROCM_BRANCH" https://github.com/ROCm/hip-tests.git

Build HIP tests from source.

export HIPTESTS_DIR="$(readlink -f hip-tests)"
cd "$HIPTESTS_DIR"
mkdir -p build; cd build
cmake ../catch -DHIP_PLATFORM=amd -DHIP_PATH=$CLR_DIR/build/install  # or any path where HIP is installed; for example: ``/opt/rocm``
make build_tests
ctest # run tests

HIP catch tests are built in $HIPTESTS_DIR/build.

To run any single catch test, use this example:

cd $HIPTESTS_DIR/build/catch_tests/unit/texture
./TextureTest

Build a HIP Catch2 standalone test. (Optional)

cd "$HIPTESTS_DIR"
hipcc $HIPTESTS_DIR/catch/unit/memory/hipPointerGetAttributes.cc \
-I ./catch/include ./catch/hipTestMain/standalone_main.cc \
-I ./catch/external/Catch2 -o hipPointerGetAttributes
./hipPointerGetAttributes
...

All tests passed

NVIDIA

The commands to build HIP tests on an NVIDIA platform are the same as on an AMD platform. However, you must first set -DHIP_PLATFORM=nvidia.

Run HIP#

After installation and building HIP, you can compile your application and run. A simple SAXPY example can be found in the ROCm-examples repository and the guide on how to build and run it is in the SAXPY tutorial
