HI Everyone, Well it looks like we have a topic we do need to discuss soon, possibly for an errata item for 4.2. There seems to be more ambiguity about what is implied by the wording in section 11.3 concerning MPI_SESSION_INIT – Session instantiation is intended to be a lightweight operation than many of us may have realized. We don’t explicitly state whether this call is in any sense synchronizing with other processes. We’ve talked about this so long, for instance in terms of asymmetry with MPI_SESSION_FINALIZE, that we didn’t consider that an implementor may construe that MPI_SESSION_INIT has the same implicit synchronization behavior as MPI_INIT. We may want to add something in an errata to clarify what lightweight means. Again I will not be able to call in on Monday but perhaps if others want to discuss? The meeting will be automatically recorded BTW.
