This is a proposal for MPI 2.1, Ballot 4. This is a follow up to: MPI_PROCNULL and RMA Part 2 in http://www.cs.uiuc.edu/homes/wgropp/projects/parallel/MPI/mpi-errata/index.h... with mail discussion in http://www.cs.uiuc.edu/homes/wgropp/projects/parallel/MPI/mpi-errata/discuss... Proposal for MPI 2.1, Ballot 4: ------------------------------- Proposed text MPI-2, page 114, after line 4 (and after the lines added about MPI_PROC_NULL), add After an RMA operations with rank MPI_PROC_NULL, it is still necessary to finish the RMA epoch with the synchronization method that has started the epoch. ------------------------------- Reason: With Ballot 2, the Forum included MPI_PROC_NULL also in RMA calls. The proposed text clarifies a till exiting open question. ------------------------------- Discussion should be done through the new mailing list mpi-21_at_cs.uiuc.edu.
