Hi Brandon, Thanks for volunteering! do I need some additional permissions somewhere? Wesley (cc'd) can give you access to the private MPI Forum Github repo. I think there is merit in this suggestion for a nonblocking and persistent versions of MPI_Sendrecv and MPI_Sendrecv_replace. I’m forwarding this to the point-to-point working group email list so that others have a chance to see it and comment.

This is different from MPI_ISEND + MPI_IRECV + MPI_WAITALL in that 1 fewer request is involved and is far more convenient for developers who wish to convert blocking code to nonblocking. Additionally there are not persistent versions currently. At a minimum I would like to add: * MPI_ISENDRECV * MPI_ISENDRECV_REPLACE Persistent versions would involve adding: * MPI_SENDRECV_INIT * MPI_SENDRECV_REPLACE_INIT If people think it is a good idea I can to put the relevant text together in a branch. Is there a place for that under https://github.com/mpiwg-p2p? or do I need some additional permissions somewhere? — You are receiving this because you are subscribed to this thread.
