In MPI-2, the are not compatible, but in MPI-3, it's ok as long as there is no overlap. I've attached an updated PDF with both MPI-2 and MPI-3 tables. ~Jim.

There seem to be a few errors here: load + Put/Acc and store + Get should be NOVL. -- Pavan On 10/10/2011 02:35 PM, James Dinan wrote: > Hi All, > > We discussed creating a table that shows compatibility between > concurrent RMA operations.

We are going to discuss those issues at the next telecon which will be announced soon. Thanks for sending the implementation to the forum. This enables us to vote if we decide to do so.

I think that is reasonable, but I think the bar will be higher. Did you guys really discuss a solution that would break backward compatibility with the RMA ticket?

Is it reasonable to assume that we can break backward compatibility of the MPI-3 RMA ticket with a follow-on ticket as long as it happens before MPI 3.0 is ratified? ~Jim.

Who has a complete implementation of MPI-3 RMA? Can it be distributed for inspection?
