It's only half a solution right now.  Hacking Hydra is a bit more
difficult for me.  Not sure how long before I can solve that in a
manner that the MPICH folks find acceptable.

I was taught by my postdoctoral advisor that any library or package that had stdout or stderr output hardwired that could not be turned off without losing functionality was rude and poorly thought out but then that guy probably never amounted to anything I guess so I should just ignore him since he doesn’t represent main stream thought.

A colleague of mine suggested that libraries shouldn't be calling
MPI_Abort but rather return an error code to the application and let
them decide how to handle it, but he learned MPI from Bill Gropp, so
he might not know anything ;-)

I apologize for being unpleasant earlier.

Best,

Jeff

We have already prepared and presented useful error messages to the user about the situation and would like to avoid having these additional messages printed (that often make the situation look worse than it is)
