MPI

Install MPICH, Open MPI, Intel MPI or HPC-X for supported compiler and runner combinations. Use exported compiler wrappers and launcher settings with fpm, CMake or Meson.

Supported combinations

Runner compiler mpi
Ubuntu gfortran mpich, openmpi
Ubuntu ifx intelmpi
Ubuntu nvfortran hpcx
macOS gfortran mpich, openmpi
Windows ifx intelmpi

Inputs

Input Default Value
mpi none none, mpich, openmpi, intelmpi, hpcx
mpi-version empty Version, latest, or empty; requires mpi
