[OMPI users] fork / exec from an MPI process

[tom fogal]

Our project is fork / exec'ing in some cases to provide a service for
some of the processes within our MPI job.  Open MPI spews big warnings
to the terminal about this.  It explains how to disable the message,
but I'd really like it to not pop up regardless.

The child process does not perform any MPI calls, or even access the
network.  In many cases, it probably doesn't even use sockets.

Is there any way I could disable this message?  Perhaps some special
Open MPI code I could insert:

  #ifdef OPENMPI
    disable_fork_exec_warning();
  #endif

?

Thanks,
