Before you begin
- Install Arm Compiler for HPC. For more information, see our instructions on Installing Arm Compiler for HPC.
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.
