Barry,

Do you need a portable solution that works across different MPI implementations,

This is well outside the standard so I don't see this being viable.

or does a solution for making just MPICH silent address your need? If the latter, you could probably convince someone on the MPICH team to add an environment variable for MPICH and a command-line "quiet" flag for hydra/mpiexec.

Even better would be an MPIX_Set_error_verbosity() or MPIX_Abort_quietly().
