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

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 amd-stg-open https://github.com/RadeonOpenCompute/llvm-project.git
cd llvm-project
mkdir -p build && cd build
cmake -DCMAKE_INSTALL_PREFIX=/opt/rocm/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=/opt/rocm/llvm/bin:$PATH
git clone -b amd-stg-open https://github.com/RadeonOpenCompute/ROCm-Device-Libs.git
cd ROCm-Device-Libs
mkdir -p build && cd build
CC=clang CXX=clang++ cmake -DLLVM_DIR=/opt/rocm/llvm -DCMAKE_BUILD_TYPE=Release -DLLVM_ENABLE_WERROR=1 -DLLVM_ENABLE_ASSERTIONS=1 -DCMAKE_INSTALL_PREFIX=/opt/rocm ..
make -j
sudo make install

NVIDIA Platform

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

  • Add the ROCm package server to your system as per the OS-specific guide available here.
  • Install the "hip-runtime-nvidia" and "hip-devel" package. This will install CUDA SDK and the HIP porting layer.
apt-get install hip-runtime-nvidia hip-devel
  • Default paths and environment variables:
    • By default HIP looks for CUDA SDK in /usr/local/cuda (can be overriden by setting CUDA_PATH env variable).
    • By default HIP is installed into /opt/rocm/hip (can be overridden by setting HIP_PATH environment variable).
    • Optionally, consider adding /opt/rocm/bin to your path to make it easier to use the tools.

Building HIP from source

Get HIP source code

git clone -b develop https://github.com/ROCm-Developer-Tools/hipamd.git
git clone -b develop https://github.com/ROCm-Developer-Tools/hip.git
git clone -b develop https://github.com/ROCm-Developer-Tools/ROCclr.git
git clone -b develop https://github.com/RadeonOpenCompute/ROCm-OpenCL-Runtime.git

Set the environment variables

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

Build HIP

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="/opt/rocm/" -DCMAKE_INSTALL_PREFIX=$PWD/install ..
make -j$(nproc)
sudo make install

Note: If you don't specify CMAKE_INSTALL_PREFIX, hip runtime will be installed to "/opt/rocm/hip". By default, release version of AMDHIP is built.

Default paths and environment variables

  • By default HIP looks for HSA in /opt/rocm/hsa (can be overridden by setting HSA_PATH environment variable).
  • By default HIP is installed into /opt/rocm/hip (can be overridden by setting HIP_PATH environment variable).
  • By default HIP looks for clang in /opt/rocm/llvm/bin (can be overridden by setting HIP_CLANG_PATH environment variable)
  • By default HIP looks for device library in /opt/rocm/lib (can be overridden by setting DEVICE_LIB_PATH environment variable).
  • Optionally, consider adding /opt/rocm/bin to your PATH to make it easier to use the tools.
  • Optionally, set HIPCC_VERBOSE=7 to output the command line for compilation.

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

Verify your installation

Run hipconfig (instructions below assume default installation path) :

/opt/rocm/bin/hipconfig --full

Compile and run the square sample.
