HIP: Heterogenous-computing Interface for Portability
|
HIP can be easily installed using pre-built binary packages using the package manager for your platform.
HIP code can be developed either on AMD ROCm platform using HIP-Clang compiler, or a CUDA platform with nvcc installed.
ROCM_PATH is path where ROCM is installed. BY default ROCM_PATH is /opt/rocm. ``` sudo apt install mesa-common-dev sudo apt install clang sudo apt install comgr sudo apt-get -y install rocm-dkms ``` Public link for Rocm installation https://rocmdocs.amd.com/en/latest/Installation_Guide/Installation-Guide.html
HIP-Clang is the compiler for compiling HIP programs on AMD platform.
HIP-Clang can be built manually: ``` git clone -b rocm-5.0.x https://github.com/RadeonOpenCompute/llvm-project.git cd llvm-project mkdir -p build && cd build cmake -DCMAKE_INSTALL_PREFIX=<ROCM_PATH>/llvm -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_ASSERTIONS=1 -DLLVM_TARGETS_TO_BUILD="AMDGPU;X86" -DLLVM_ENABLE_PROJECTS="clang;lld;compiler-rt" ../llvm make -j sudo make install ``` Rocm device library can be manually built as following, ``` export PATH=<ROCM_PATH>/llvm/bin:$PATH git clone -b rocm-5.0.x https://github.com/RadeonOpenCompute/ROCm-Device-Libs.git cd ROCm-Device-Libs mkdir -p build && cd build CC=clang CXX=clang++ cmake -DLLVM_DIR=<ROCM_PATH>/llvm -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_WERROR=1 -DLLVM_ENABLE_ASSERTIONS=1 -DCMAKE_INSTALL_PREFIX=<ROCM_PATH> .. make -j sudo make install ```
HIP-nvcc is the compiler for HIP program compilation on NVIDIA platform.
``` git clone -b rocm-5.0.x https://github.com/ROCm-Developer-Tools/hipamd.git git clone -b rocm-5.0.x https://github.com/ROCm-Developer-Tools/hip.git git clone -b rocm-5.0.x https://github.com/ROCm-Developer-Tools/ROCclr.git git clone -b rocm-5.0.x https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime.git ```
``` export HIPAMD_DIR="$(readlink -f hipamd)" export HIP_DIR="$(readlink -f hip)" export ROCclr_DIR="$(readlink -f ROCclr)" export OPENCL_DIR="$(readlink -f ROCm-OpenCL-Runtime)" ```
ROCclr is defined on AMD platform that HIP use Radeon Open Compute Common Language Runtime (ROCclr), which is a virtual device interface that HIP runtimes interact with different backends. See https://github.com/ROCm-Developer-Tools/ROCclr
HIPAMD repository provides implementation specifically for AMD platform. See https://github.com/ROCm-Developer-Tools/hipamd
``` cd "$HIPAMD_DIR" mkdir -p build; cd build cmake -DHIP_COMMON_DIR=$HIP_DIR -DAMD_OPENCL_PATH=$OPENCL_DIR -DROCCLR_PATH=$ROCCLR_DIR -DCMAKE_PREFIX_PATH="<ROCM_PATH>/" -DCMAKE_INSTALL_PREFIX=$PWD/install .. make -j sudo make install ```
Note: If you don't specify CMAKE_INSTALL_PREFIX, hip runtime will be installed to "<ROCM_PATH>/hip". By default, release version of AMDHIP is built.
After installation, make sure HIP_PATH is pointed to /where/to/install/hip
``` git clone -b rocm-5.0.x https://github.com/ROCm-Developer-Tools/hip.git git clone -b rocm-5.0.x https://github.com/ROCm-Developer-Tools/hipamd.git ```
``` export HIP_DIR="$(readlink -f hip)" export HIPAMD_DIR="$(readlink -f hipamd)" ```
``` cd "$HIPAMD_DIR" mkdir -p build; cd build cmake -DHIP_COMMON_DIR=$HIP_DIR -DHIP_PLATFORM=nvidia -DCMAKE_INSTALL_PREFIX=$PWD/install .. make -j sudo make install ```
Run hipconfig (instructions below assume default installation path) : ```shell <ROCM_PATH>/bin/hipconfig –full ``` or
```shell $PWD/install/bin/hipconfig –full ```
Compile and run the square sample.
