Prerequisites setup script

For your convenience, we provide the setup script,rocAL-setup.py, which installs all required dependencies. Run this script only once.

python rocAL-setup.py --directory [setup directory - optional (default:~/)]
                      --rocm_path [ROCm Installation Path - optional (default:/opt/rocm)]
                      --backend   [rocAL Dependency Backend - optional (default:HIP) [options:OCL/HIP]]
                      --ffmpeg    [FFMPEG Installation - optional (default:OFF)[options:ON/OFF]]
                      --reinstall [Reinstall - optional (default:OFF)[options:ON/OFF]]

Installation instructions

The installation process uses the following steps:

• ROCm-supported hardware install verification

• Install ROCm 6.1.0 or later with amdgpu-install with --usecase=rocm

Important

Use either package install or source install as described below.

Package install

Install rocAL runtime, development, and test packages.

• Runtime package - rocal only provides the dynamic libraries
• Development package - rocal-dev/rocal-devel provides the libraries, executables, header files, and samples
• Test package - rocal-test provides ctest to verify installation

Ubuntu

sudo apt-get install rocal rocal-dev rocal-test

CentOS/RedHat

sudo yum install rocal rocal-devel rocal-test

SLES

sudo zypper install rocal rocal-devel rocal-test

Important

• Package install requires TurboJPEG manual install

  git clone -b 3.0.2 https://github.com/libjpeg-turbo/libjpeg-turbo.git
  mkdir tj-build && cd tj-build
  cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=RELEASE -DENABLE_STATIC=FALSE -DCMAKE_INSTALL_DEFAULT_LIBDIR=lib -DWITH_JPEG8=TRUE ../libjpeg-turbo/
  make -j8 && sudo make install
  

• CentOS/RedHat/SLES requires additional FFMPEG Dev package manual install
• rocAL Python module: To use python module, you can set PYTHONPATH:
  • export PYTHONPATH=/opt/rocm/lib:$PYTHONPATH

Source install

To build rocAL from source and install, follow the steps below:

• Clone rocAL source code

git clone https://github.com/ROCm/rocAL.git

Note

rocAL has support for two GPU backends: OPENCL and HIP:

HIP Backend

• Instructions for building rocAL with the HIP GPU backend (default GPU backend):

  • run the setup script to install all the dependencies required by the HIP GPU backend:

  cd rocAL
  python rocAL-setup.py

  • run the below commands to build rocAL with the HIP GPU backend:

  mkdir build-hip
  cd build-hip
  cmake ../
  make -j8
  sudo cmake --build . --target PyPackageInstall
  sudo make install

Note

• PyPackageInstall used for rocal_pybind installation

Important

• Use -D PYTHON_VERSION_SUGGESTED=3.x with cmake for using a specific Python3 version if required.
• Use -D AUDIO_SUPPORT=ON to enable Audio features, Audio support will be enabled by default with ROCm versions > 6.2

• run tests - test option instructions

make test

Note

To run tests with verbose option, use make test ARGS="-VV".

OpenCL Backend

• Instructions for building rocAL with OPENCL GPU backend

Note

• rocAL_pybind is not supported on OPENCL backend
• rocAL cannot be installed for both GPU backends in the same default folder (i.e., /opt/rocm/)
• if an app interested in installing rocAL with both GPU backends, then add -DCMAKE_INSTALL_PREFIX in the cmake commands to install rocAL with OPENCL and HIP backends into two separate custom folders.

Verify installation

• The installer will copy
  • Executables into /opt/rocm/bin
  • Libraries into /opt/rocm/lib
  • rocal_pybind into /opt/rocm/lib
  • Header files into /opt/rocm/include/rocal
  • Apps, & Samples folder into /opt/rocm/share/rocal
  • Documents folder into /opt/rocm/share/doc/rocal

Verify with rocal-test package

Test package will install ctest module to test rocAL. Follow below steps to test package install

mkdir rocAL-test && cd rocAL-test
cmake /opt/rocm/share/rocal/test/
ctest -VV

Note

• Make sure all rocAL required libraries are in your PATH
• RHEL/SLES - Export FFMPEG libraries into your PATH
  • export LD_LIBRARY_PATH=/usr/local/lib:/usr/local/lib64/:/usr/local/lib/x86_64-linux-gnu:$LD_LIBRARY_PATH

export PATH=$PATH:/opt/rocm/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/rocm/lib

Verify rocAL PyBind with rocal-test package

Test package will install ctest module to test rocAL PyBindings. Follow below steps to test package install

mkdir rocal-pybind-test && cd rocal-pybind-test
cmake /opt/rocm/share/rocal/test/pybind
ctest -VV

Note

• Make sure all rocAL required libraries are in your PATH

export PATH=$PATH:/opt/rocm/bin
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/rocm/lib
export PYTHONPATH=/opt/rocm/lib:$PYTHONPATH
