Hi All, Reviewing my notes from the WG meeting, it appears that the following errata would clarify many misunderstandings of the MPI-3 RMA spec: 1) Clarify the target process rank for load/store operations on shared memory windows. This is needed so that synchronization operations (e.g. lock/unlock and PSCW) are well defined on shared memory windows. 2) Clarify that that while there is one copy of the window data in memory in the unified memory model, there are still public and private views that must be synchronized according to the RMA semantics. Is there enough support for these that they should be captured for future discussion? Cheers, ~Jim.
