I’m sorry to have missed this — I’m very much interested in C++ binding and interoperability issues. I know Jeff at least is involved in our weekly C++ heterogeneity phone meetings — we’re trying to move the Standard to support multiple memory spaces in a sane way, and I think it helps to have RDMA represented there as well. We’ve also thought a bit about wrapping MPI RDMA in Kokkos, and about making the mdspan proposal flexible enough that we could perhaps support RDMA with it as well. The most interesting bit might be actually introducing semantics for noncoherent shared memory into the Standard — I think we want to go there eventually but it is really hard, and I think y’all are well equipped to help.

Folks, Sorry, I forgot to send out the call-in information yesterday. We'll use this: http://argonne.bluejeans.com/balaji.anl.gov I'll add it to the calendar invite as well. -- Pavan

Hi Pavan, I don't see a link to the blue jeans connection info. Where can I find that? Thanks, ~Jim.

All, We are restarting the RMA WG telecons. A subset of the following proposals will be discussed during this call. - Interoperability of MPI shared memory with C11, C++11 language semantics. Lead: Bill Gropp - MPI Generalized atomics. Lead: Pavan Balaji - Neighborhood communication in RMA. Lead: Nathan Hjelm - Nonblocking RMA synchronization. Lead: Pavan Balaji - RMA Notify. Leads: Jim and Torsten - MPI_IN_PLACE semantics for collectives on shared memory. Lead: Pavan Balaji - Relax constraints on MPI_WIN_SHARED_QUERY. Lead: Jeff Hammond - <Unnamed proposal>. Lead: Nathan Hjelm
