How do I check the version of MPICH?

Question

As stated in the question, what is the command that lists the current version of MPICH? I am running CentOS.

Answer 1

There is a string called MPICH_VERSION in mpi.h that is set to the version. Cray, for example, provides their own application launcher so there isn't the standard set of executables already mentioned for querying the MPICH version.
