[MPICH] any way to ask nemesis to turn-off and turn of active polling ?

[chong tan]

My issue is like this :

among all the processess, some will get to the point of first MPI communication points faster than
than other.  Is there a way that I tell nemesis to start without doing active polling, and then turn
on active polling with some function ?

Or should I just use MPI_Barrier() on that ?

thanks
tan
