# Prerequisites
|
|
|
|
HIP code can be developed either on AMD ROCm platform using HIP-Clang compiler, or a CUDA platform with nvcc installed.
|
|
Before build and run HIP, make sure drivers and pre-build packages are installed properly on the platform.
|
|
|
|
## AMD platform
|
|
Install ROCm packages (see ROCm Installation Guide on AMD public documentation site (https://docs.amd.com/)) or install pre-built binary packages using the package manager,
|
|
|
|
```
|
|
sudo apt install mesa-common-dev
|
|
sudo apt install clang
|
|
sudo apt install comgr
|
|
sudo apt-get -y install rocm-dkms
|
|
```
|
|
|
|
## NVIDIA platform
|
|
|
|
Install Nvidia driver and pre-build packages (see HIP Installation Guide at https://docs.amd.com/ for the release)
|
|
|
|
## Branch of repository
|
|
|
|
Before get HIP source code, set the expected branch of repository at the variable HIP_BRANCH.
|
|
For example, for ROCm5.0 release branch, set
|
|
```
|
|
export HIP_BRANCH=rocm-5.0.x
|
|
```
|
|
|
|
ROCm5.1 release branch, set
|
|
```
|
|
export HIP_BRANCH=rocm-5.1.x
|
|
```
|
|
Similiar format for future branches.
|
|
|
|
ROCM_PATH is path where ROCM is installed. BY default ROCM_PATH is at /opt/rocm.
|
|

# Build HIP on AMD platform
|
|
|
|
|
|
## Get HIP source code
|
|
|
|
```
|
|
git clone -b $HIP_BRANCH https://github.com/ROCm-Developer-Tools/hipamd.git
|
|
git clone -b $HIP_BRANCH https://github.com/ROCm-Developer-Tools/hip.git
|
|
git clone -b $HIP_BRANCH https://github.com/ROCm-Developer-Tools/ROCclr.git
|
|
```
|
|
|
|
## Set the environment variables
|
|
|
|
```
|
|
export HIPAMD_DIR="$(readlink -f hipamd)"
|
|
export HIP_DIR="$(readlink -f hip)"
|
|
```
|
|
|
|
ROCclr is defined on AMD platform that HIP use Radeon Open Compute Common Language Runtime (ROCclr), which is a virtual device interface that HIP runtimes interact with different backends.
|
|
See https://github.com/ROCm-Developer-Tools/ROCclr
|
|
|
|
HIPAMD repository provides implementation specifically for AMD platform.
|
|
See https://github.com/ROCm-Developer-Tools/hipamd
|
|
|
|
## Build HIP
|
|
|
|
```
|
|
cd "$HIPAMD_DIR"
|
|
mkdir -p build; cd build
|
|
cmake -DHIP_COMMON_DIR=$HIP_DIR -DCMAKE_PREFIX_PATH="<ROCM_PATH>/" -DCMAKE_INSTALL_PREFIX=$PWD/install ..
|
|
make -j$(nproc)
|
|
sudo make install
|
|
```
|
|
|
|
Note: If you don't specify CMAKE_INSTALL_PREFIX, hip runtime will be installed to "<ROCM_PATH>/hip".
|
|
By default, release version of AMDHIP is built.
|
|
|
|
## Default paths and environment variables
|
|
|
|
* By default HIP looks for HSA in <ROCM_PATH>/hsa (can be overridden by setting HSA_PATH environment variable).
|
|
* By default HIP is installed into <ROCM_PATH>/hip (can be overridden by setting HIP_PATH environment variable).
|
|
* By default HIP looks for clang in <ROCM_PATH>/llvm/bin (can be overridden by setting HIP_CLANG_PATH environment variable)
|
|
* By default HIP looks for device library in <ROCM_PATH>/lib (can be overridden by setting DEVICE_LIB_PATH environment variable).
|
|
* Optionally, consider adding <ROCM_PATH>/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 make install command, make sure HIP_PATH is pointed to $PWD/install/hip.
|
|
|
|
## Build HIP tests
|
|
|
|
### Build HIP directed tests
|
|
Developers can build HIP directed tests right after build HIP commands,
|
|
|
|
```
|
|
sudo make install
|
|
make -j$(nproc) build_tests
|
|
```
|
|
By default, all HIP directed tests will be built and generated under the folder $HIPAMD_DIR/build/directed_tests.
|
|
Take HIP directed device APIs tests, as an example, all available test applications will have executable files generated under,
|
|
$HIPAMD_DIR/build/directed_tests/runtimeApi/device.
|
|
|
|
Run all HIP directed_tests, use the command,
|
|
|
|
```
|
|
ctest
|
|
```
|
|
Or
|
|
```
|
|
make test
|
|
```
|
|
|
|
Build and run a single directed test, use the follow command as an example,
|
|
|
|
```
|
|
make directed_tests.texture.hipTexObjPitch
|
|
cd $HIPAMD_DIR/build/directed_tests/texcture
|
|
./hipTexObjPitch
|
|
```
|
|
Please note, the integrated HIP directed tests, will be deprecated in future release.
|
|
|
|
|
|
### Build HIP catch tests
|
|
|
|
After build and install HIP commands, catch tests can be built via the following instructions,
|
|
|
|
```
|
|
cd "$HIP_DIR"
|
|
mkdir -p build; cd build
|
|
export HIP_PATH=$HIPAMD_DIR/build
|
|
cmake ../tests/catch/ -DHIP_PLATFORM=amd
|
|
make -j$(nproc) build_tests
|
|
ctest # run tests
|
|
```
|
|
|
|
HIP catch tests are built under the folder $HIP_DIR/build.
|
|
|
|
To run a single catch test, the following is an example,
|
|
|
|
```
|
|
cd $HIP_DIR/build/unit/texture
|
|
./TextureTest
|
|
```
|
|
|
|
### Build HIP Catch2 standalone test
|
|
|
|
HIP Catch2 supports build a standalone test, for example,
|
|
|
|
```
|
|
export PATH=$HIP_DIR/bin:$PATH
|
|
export HIP_PATH=$HIPAMD_DIR/build/install
|
|
|
|
hipcc $HIP_DIR/tests/catch/unit/memory/hipPointerGetAttributes.cc -I ./tests/catch/include ./tests/catch/hipTestMain/standalone_main.cc -I ./tests/catch/external/Catch2 -g -o hipPointerGetAttributes
|
|
./hipPointerGetAttributes
|
|
...
|
|
|
|
All tests passed
|
|
```
|
|
|
|
HIP catch tests, especially new architectured Catch2, will be official HIP tests in the repository and can be built alone as with the instructions shown above.
|
|
|
|
# Build HIP on NVIDIA platform
|
|
|
|
|
|
## Get HIP source code
|
|
|
|
```
|
|
git clone -b $HIP_BRANCH https://github.com/ROCm-Developer-Tools/hip.git
|
|
git clone -b $HIP_BRANCH https://github.com/ROCm-Developer-Tools/hipamd.git
|
|
```
|
|
|
|
## Set the environment variables
|
|
|
|
```
|
|
export HIP_DIR="$(readlink -f hip)"
|
|
export HIPAMD_DIR="$(readlink -f hipamd)"
|
|
```
|
|
|
|
## Build HIP
|
|
|
|
```
|
|
cd "$HIPAMD_DIR"
|
|
mkdir -p build; cd build
|
|
cmake -DHIP_COMMON_DIR=$HIP_DIR -DHIP_PLATFORM=nvidia -DCMAKE_INSTALL_PREFIX=$PWD/install ..
|
|
make -j$(nproc)
|
|
sudo make install
|
|
```
|
|
|
|
## Build HIP tests
|
|
Build HIP tests commands on NVIDIA platform are basically the same as AMD, except set -DHIP_PLATFORM=nvidia.
|
|
|
|
# Run HIP
|
|
|
|
Compile and run the [square sample](https://github.com/ROCm-Developer-Tools/HIP/tree/rocm-5.0.x/samples/0_Intro/square).
