HIP: Heterogenous-computing Interface for Portability
Table of Contents

Installing pre-built packages

HIP can be easily installed using pre-built binary packages using the package manager for your platform.

Prerequisites

HIP code can be developed either on AMD ROCm platform using HIP-Clang compiler, or a CUDA platform with nvcc installed.

AMD Platform

ROCM_PATH is path where ROCM is installed. BY default ROCM_PATH is /opt/rocm.

1 sudo apt install mesa-common-dev
2 sudo apt install clang
3 sudo apt install comgr
4 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:

1 git clone -b rocm-5.0.x https://github.com/RadeonOpenCompute/llvm-project.git
2 cd llvm-project
3 mkdir -p build && cd build
4 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
5 make -j
6 sudo make install

Rocm device library can be manually built as following,

1 export PATH=<ROCM_PATH>/llvm/bin:$PATH
2 git clone -b rocm-5.0.x https://github.com/RadeonOpenCompute/ROCm-Device-Libs.git
3 cd ROCm-Device-Libs
4 mkdir -p build && cd build
5 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> ..
6 make -j
7 sudo make install

NVIDIA Platform

HIP-nvcc is the compiler for HIP program compilation on NVIDIA platform.

Building HIP from source on AMD platform

Get HIP source code

1 git clone -b rocm-5.0.x https://github.com/ROCm-Developer-Tools/hipamd.git
2 git clone -b rocm-5.0.x https://github.com/ROCm-Developer-Tools/hip.git
3 git clone -b rocm-5.0.x https://github.com/ROCm-Developer-Tools/ROCclr.git
4 git clone -b rocm-5.0.x https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime.git

Set the environment variables

1 export HIPAMD_DIR="$(readlink -f hipamd)"
2 export HIP_DIR="$(readlink -f hip)"
3 export ROCclr_DIR="$(readlink -f ROCclr)"
4 export OPENCL_DIR="$(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

Build HIP

1 cd "$HIPAMD_DIR"
2 mkdir -p build; cd build
3 cmake -DHIP_COMMON_DIR=$HIP_DIR -DAMD_OPENCL_PATH=$OPENCL_DIR -DROCCLR_PATH=$ROCCLR_DIR -DCMAKE_PREFIX_PATH="<ROCM_PATH>/" -DCMAKE_INSTALL_PREFIX=$PWD/install ..
4 make -j$(nproc)
5 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.

Default paths and environment variables

After installation, make sure HIP_PATH is pointed to /where/to/install/hip

Building HIP from source on NVIDIA platform

Get HIP source code

1 git clone -b rocm-5.0.x https://github.com/ROCm-Developer-Tools/hip.git
2 git clone -b rocm-5.0.x https://github.com/ROCm-Developer-Tools/hipamd.git

Set the environment variables

1 export HIP_DIR="$(readlink -f hip)"
2 export HIPAMD_DIR="$(readlink -f hipamd)"

Build HIP

1 cd "$HIPAMD_DIR"
2 mkdir -p build; cd build
3 cmake -DHIP_COMMON_DIR=$HIP_DIR -DHIP_PLATFORM=nvidia -DCMAKE_INSTALL_PREFIX=$PWD/install ..
4 make -j$(nproc)
5 sudo make install

Verify your installation

Run hipconfig (instructions below assume default installation path) :

1 <ROCM_PATH>/bin/hipconfig --full

or

1 $PWD/install/bin/hipconfig --full

Compile and run the square sample.
