- permit SYSTEMMPI user adjustments via
etc/config.{csh,sh}/mpi-system
This can be a convenient place for setting up SYSTEMMPI for OpenFOAM
without adjusting bashrc, prefs.sh ...
- add a USERMPI type. This represents any generic mpi implementation.
The user is responsible for supplying an appropriate
wmake/rules/General/mplibUSERMPI file and managing all settings.
This type of setup can be useful in combination with specific build
systems (SPACK, EASYBUILD, etc) or module systems for which the MPI
variant is part of the installed configuration.
