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.html with mail discussion in http://www.cs.uiuc.edu/homes/wgropp/projects/parallel/MPI/mpi-errata/discuss/procnull2/ 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@XXXXXXXXXXXX I have sent out this mail with CC through the old general list mpi-21@mpi-forum.org Best regards Rolf Dr. Rolf Rabenseifner . . . . . . . . . .. email rabenseifner@XXXXXXX High Performance Computing Center (HLRS) . phone ++49(0)711/685-65530 University of Stuttgart . . . . . . . . .. fax ++49(0)711 / 685-65832 Head of Dpmt Parallel Computing . . . www.hlrs.de/people/rabenseifner Nobelstr. 19, D-70550 Stuttgart, Germany .
