Overview

This topic describes how to build Open MPI with Arm Compiler for HPC.

Open MPI is freely available. The Open MPI project is an open source MPI implementation developed and maintained by a consortium of academics, researchers and industry partners.

For more information on Open MPI, visit the Open MPI webpage.

Note: Arm recommends that you rebuild your MPI implementation (Open MPI, MVAPICH, MPICH) after each installation of a new version of Arm Compiler for HPC. This ensures that the Fortran interface incorporates any changes to the armflang module format, and that the correct run-time libraries are used.
