Installation

Installation#

To install hipRAND, you can choose between the following two methods:

Both the methods are described below.

Install using prebuilt packages#

To install the prebuilt hipRAND packages, you require a ROCm-enabled platform. For information on ROCm installation, see the ROCm installation for Linux page. After installing ROCm or enabling the ROCm repositories, you can install hipRAND using the system package manager.

For Ubuntu and Debian:

sudo apt-get install hiprand

For CentOS:

sudo yum install hiprand

For SLES:

sudo dnf install hiprand

This installs hipRAND in the /opt/rocm directory.

Build hipRAND from source#

This section provides the information required to build hipRAND from source.

Requirements#

To build hipRAND, CMake version 3.10 or later is required.

Additionally, to build hipRAND for ROCm software, the following softwares are required:

To build hipRAND for the CUDA platform instead, the following softwares are required:

  • The CUDA toolkit

  • cuRAND (included in the CUDA Toolkit)

Obtaining sources#

You can find the hipRAND sources in the hipRAND GitHub Repository. Use the branch that matches the system-installed version of ROCm. For example, on a system with ROCm 5.4 installed, use the following command to obtain hipRAND sources:

git checkout -b release/rocm-rel-5.4 https://github.com/ROCm/hipRAND.git

Building library#

After obtaining the sources and dependencies, build hipRAND for ROCm software using the installation script:

cd hipRAND
./install --install

This automatically builds all required dependencies, excluding Git and the requirements listed above, and installs the project to /opt/rocm if everything went well. See ./install --help for further information. The clients, enabled by option --clients, consist of the hipRAND tests and add the additional dependency of googletest.

Building with CMake#

For a more elaborate installation process, build hipRAND manually using CMake. This enables certain configuration options that are not exposed to the ./install script. In general, you can build hipRAND using CMake with the following configuration:

cd hipRAND; mkdir build; cd build
# Configure the project
CXX=<compiler> cmake [options] ..
# Build
make -j$(nproc)
# Optionally, run the tests
ctest --output-on-failure
# Install
[sudo] make install

Where <compiler> should be set to hipcc or amdclang on ROCm software or to a regular C++ compiler such as g++ on a CUDA platform. The default build configuration is Release.

Here are the CMake options:

  • BUILD_WITH_LIB decides whether to build hipRAND with the rocRAND or cuRAND backend. If set to CUDA, hipRAND is built using the cuRAND backend. Otherwise, the rocRAND backend is used.

  • BUILD_FORTRAN_WRAPPER builds the Fortran wrapper when set to ON. Defaults to OFF.

  • BUILD_TEST builds the hipRAND tests when set to ON. Defaults to OFF.

  • BUILD_BENCHMARK builds the hipRAND benchmarks when set to ON. Defaults to OFF.

  • BUILD_ADDRESS_SANITIZER builds with address sanitization enabled when set to ON. Defaults to OFF.

  • ROCRAND_PATH specifies a rocRAND install other than the default system installed one.

  • DOWNLOAD_ROCRAND downloads and installs rocRAND in the build directory when set to ON. Defaults to OFF.

  • DEPENDENCIES_FORCE_DOWNLOAD downloads and builds the dependencies instead of using system-installed dependencies when set to ON. Defaults to OFF.

If using ROCRAND_PATH or DOWNLOAD_ROCRAND when rocRAND is already installed in the default location in the system then, use CMAKE_NO_SYSTEM_FROM_IMPORTED=ON while configuring the project. Failing to do so might resolve the rocRAND headers to the system-installed version instead of the specified version, leading to errors or missing functionalities.

Common build errors#

  • Could not find a package configuration file provided by "rocrand" with any of the following names:

rocrandConfig.cmake
rocrand-config.cmake

    Solution: install rocRAND.

  • Could not find a package configuration file provided by "ROCM" with any of the following names:

ROCMConfig.cmake
rocm-config.cmake

    Solution: install ROCm CMake modules.

Building Python API wrapper#

This section provides information required to build the hipRAND Python API wrapper.

Requirements#

The hipRAND Python API Wrapper requires the following dependencies:

  • hipRAND

  • Python 3.5

  • NumPy (will be installed automatically as a dependency if necessary)

Note

If hipRAND is built from sources but not installed or rather installed in a non-standard directory, then set the ROCRAND_PATH or HIPRAND_PATH environment variable to the path containing libhiprand.so as shown below:

export HIPRAND_PATH=~/hipRAND/build/library/

Installation#

To install Python hipRAND module using pip:

cd hipRAND/python/hiprand
pip install .

To execute the tests:

cd hipRAND/python/hiprand
python tests/hiprand_test.py
