Installing rocALUTION on Linux

Installing rocALUTION on Linux#

rocALUTION can be installed along with ROCm as a single-node, accelerator-enabled library. To configure rocALUTION to use a different configuration such as a multi-node configuration, it must be be built from source code.

ROCm must be installed before building rocALUTION. Use the version of rocALUTION that corresponds to the installed version of ROCm.

The rocALUTION source code is available from ROCm/rocALUTION.

rocALUTION depends on the following ROCm components:

Ensure that these components are installed before installing rocALUTION. See their respective documentation for installation instructions.

For multi-node configurations, download and install OpenMP and MPI.

Create a build directory in the rocALUTION root directory. Change directory to the build directory:

mkdir build
cd build

Use CMake to generate a makefile. The ROCM_PATH directive is required. Set it to point to the ROCm installation location.

The following optional directives can also be set:

  • SUPPORT_HIP: Build rocALUTION with HIP support. ON by default.

  • SUPPORT_OMP: Build rocALUTION with OpenMP support. ON by default.

  • SUPPORT_MPI: Build rocALUTION with MPI. Set this to ON for multi-node support. OFF by default.

  • BUILD_SHARED_LIBS: Build rocALUTION as shared library. ON by default. ON is the recommended configuration.

  • BUILD_EXAMPLES: Build rocALUTION examples. ON by default.

For example, to build rocALUTION with MPI support, run this command:

cmake .. -DSUPPORT_MPI=ON -DROCM_PATH=/opt/rocm/

Use make to build rocALUTION and make install to install the rocALUTION library under the ROCm installation directory.

make
make install
