Hi All, Our regular Hybrid telecon will be on Monday 5/19 at 11am central. Webex call-in information is on the wiki: https://svn.mpi-forum.org/trac/mpi-forum-web/wiki/MPI3Hybrid In preparation for the upcoming Forum meeting, I would like to prepare an update on endpoints to deliver during the Hybrid WG session on Tuesday. Currently, I am tracking the following open items for endpoints. It would be great to touch on these briefly at the upcoming meeting. 1. Endpoints query function. This was split out into ticket #425 as a general function to query whether MPI processes exist in the same address space. 2. Discussion of communicator comparison routines in the presence of MPI processes that share an address space. This appears to also be trending toward a more general change to support models where processes share an address space. 3. Collective semantic for MPI_Comm_free. Currently we are converging on removing the special case for MPI_Comm_free and potentially creating a separate operation that can be used to free endpoints in a non-THREAD_MULTIPLE environment. We also have ticket #411 going forward for a formal reading at the next meeting. Monday is the deadline for changes, so please review. Jeff, are you planning to do anything with #381 communicator info keys (or has that moved to a different WG)? Any other agenda items? Thanks, ~Jim.
