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#

In the ROCM 7.1 release, HIP is integrated into the core ROCm projects resides in the rocm-systems monorepository. In addition, the following components are also part of the monrepository:

  • clr, AMD’s Compute Language Runtime, includes ROCclr, HIPAMD and OpenCl.

  • hipother, provides files required to support the HIP back-end implementation on some non-AMD platforms, like NVIDIA.

  • hip-tests, the HIP testing suite.

Set the repository branch using the variable: ROCM_BRANCH. For example, for ROCM 7.1, use:

export ROCM_BRANCH=release/rocm-rel-7.1

  1. Get HIP source code.

    git clone -b "$ROCM_BRANCH" [email protected]:ROCm/rocm-systems.git

  2. Set the environment variables.

    export CLR_DIR="$(readlink -f rocm-systems/projects/clr)"
export HIP_DIR="$(readlink -f rocm-systems/projects/hip)"

  3. 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=$PWD/install -DCLR_BUILD_HIP=ON -DCLR_BUILD_OCL=OFF ..
make -j$(nproc)
sudo make install

    Note

    If CMAKE_INSTALL_PREFIX is not explicitly specified, the HIP runtime will be installed at <ROCM_PATH>, which is by default at the path /opt/rocm.

    By default, the release version of HIP is built. If you need a 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.

      environment variable.

    • 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.

    1. 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

  1. Get the HIP source code.

    git clone -b "$ROCM_BRANCH" [email protected]:ROCm/rocm-systems.git

  2. Set the environment variables.

    export CLR_DIR="$(readlink -f rocm-systems/projects/clr)"
export HIP_DIR="$(readlink -f rocm-systems/projects/hip)"
export HIP_OTHER="$(readlink -f rocm-systems/projects/hipother)"

  3. Build HIP.

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

Build HIP tests#

  • Build HIP catch tests.

    HIP catch tests utilize the Catch2 testing framework.

    • Get HIP tests source code.

      git clone -b "$ROCM_BRANCH" [email protected]:ROCm/rocm-systems.git
export HIPTESTS_DIR="$(readlink -f rocm-systems/projects/hip-tests)"

    • Build HIP tests from source.

      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``
export ROCM_PATH=/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.

      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

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. Simple examples can be found in the ROCm-examples repository.
