I agree with Keith. Losing SHMEM as a client of MPI-3 is not worth symmetry or other esoteric properties.
It's entirely reasonable to say the standard leaves no-sync unified as undefined = implementation-defined. This would not be the first time.
Your statements are inconsistent. You said you agree with Keith, but then said that the no-sync unified option should be undefined. That's not what Keith is saying; he wants that to have *defined* behavior, i.e., it is valid for the client to do platform-specific memory consistency. -- Pavan -- Pavan Balaji http://www.mcs.anl.gov/~balaji
