[Mpi-forum] MPI user survey

[Supalov, Alexander]

Let me try: "Do you want to have a way in MPI-3 to trade feature richness for performance (thru subsetting, assertions, etc.)?"

We didn't ask about subsets at all because the WG is "on hold".  Do  
you want to introduce a new question?  If so, can you suggest the  
specific wording?

Note that Keith suggested an improved wording for the RMA question  
(this was buried in my reply to Dick):

"MPI one-sided communication performance (e.g., message rate and  
latency) is more important to me than supporting a rich remote memory  
access (RMA) feature set (e.g., communicators, datatypes)."

Jeff H. replied to me off-list that he liked this better than his  
suggestion.  Does anyone else have any suggestions / comments on this  
one?
