[mpich-discuss] Get universe size no longer supported?

[Jeff Hammond]

I've informed the appropriate people about the Trac issue.

I recall that MPI stipulates only that MPI_UNIVERSE_SIZE exist; it
need not be defined.

I think that MPICH might set MPI_UNIVERSE_SIZE in the process manager.
 What PM are you using?
