Thanks for the suggestion.  This is something we do intend to provide.

If I config MPICH with nemesis, there is no way I can switch off the ative polling when MPI is in progress.  I like to request a new capability, either via a new function or via an extra parameter in MPI_Init or something, the following:

nemesis is built the same as ch3:ssm  (or shm), the active polling is on by default, and can be
turned off via a flag or env var, or by calling a specific routine.

With that, we have the option to not do active polling when needed.

thanks
