Installation

Installation#

There are two main methods for installing rocThrust:

  • Install the prebuilt packages from the ROCm repositories

  • Build and install rocThrust from source files

Installing prebuilt packages#

Installing the prebuilt rocThrust packages requires a ROCm-enabled platform. See the ROCm documentation for more information. After installing ROCm or enabling the ROCm repositories, rocThrust can be obtained using the system package manager.

For Ubuntu and Debian:

sudo apt-get install rocthrust

For CentOS:

sudo yum install rocthrust

For SLES:

sudo dnf install rocthrust

This will install rocThrust into the /opt/rocm directory.

Building rocThrust from source files#

Obtaining sources#

The rocThrust sources are available from the rocThrust GitHub Repository. Use the branch that matches the system-installed version of ROCm. For example on a system that has ROCm 6.0 installed, use the following command to obtain rocThrust sources:

git clone -b release/rocm-rel-6.0 https://github.com/ROCm/rocThrust.git

Building the library#

After obtaining the sources, rocThrust can be built using the installation script. Note that this method only works on Linux, see the following sections for how to build rocThrust on Windows:

cd rocThrust
./install --install

This automatically builds all required dependencies, excluding HIP and Git, and installs the project to /opt/rocm if everything went well. See ./install --help for further information.

Building with rmake.py#

Alternatively, the rmake.py script can be used to install rocThrust. This is the recommended method to install rocThrust from source on Windows. After obtaining the sources, rocThrust can be installed this way as follows:

cd rocThrust
# The -i option will install rocThrust into /opt/rocm on Linux, and C:\hipSDK on Windows.
python rmake.py -i
# The -c option will build all clients, including unit tests
python rmake.py -c

Building with CMake#

For a more elaborate installation process, rocThrust can be built manually using CMake. This enables certain configuration options that are not exposed to the ./install and rmake.py scripts. Note that building rocThrust using CMake works on both Linux and Windows. In general, rocThrust can be built and installed using CMake as follows:

cd rocThrust;
# Configure the project
CXX=hipcc cmake -S . -B build [options]
# Build
cmake --build build
# Optionally, run the tests
ctest --output-on-failure
# Install
cmake --install build

Note

CXX must be set to hipcc to build for the ROCm platform.

The following configuration options are available, in addition to the built-in CMake options:

  • DISABLE_WERROR disables passing -Werror to the compiler during the build. ON by default.

  • BUILD_TEST controls whether to build the rocThrust and hipstdpar tests. OFF by default.

  • BUILD_HIPSTDPAR_TEST controls whether to build the hipstdpar tests. Enabling this option is only necessary when BUILD_TEST is OFF. OFF by default.

  • BUILD_BENCHMARK controls whether to build the rocThrust benchmarks. OFF by default.

  • BUILD_EXAMPLES controls whether to build rocThrust examples. OFF by default.

  • DOWNLOAD_ROCPRIM controls whether to force downloading rocPRIM, regardless of whether rocPRIM is currently installed. Defaults to OFF.

  • RNG_SEED_COUNT sets the non-repeatable random dataset count. Defaults to 0.

  • PRNG_SEEDS sets RNG seeds, to ensure reproducible random data generation. Defaults to 1.
