[mpich-discuss] detect which MPI is installed

[Hegewald]

Hi all,
do you know a mechanism to detect which kind of MPI (e.g. MPICH, OpenMPI, Win MPI etc.) is the one available via mpiexec?
I need to pass some mpiexec specific flags to my programme before actually calling mpiexec.
I know some mpiexecs support the --version flag, but not all )-:

Many TIA,
