I might have missed it, but I don't recall saying that we'll use MPI_Comm_spawn to restart a process. As I recall there are two flavors for MPI_Comm_repair one that restart a process and the other that fixes the communicator by leaving a hole. Rich, for now I'd like us to be explicit about restart vs fixing (rather than using a policy). So I suggest that we call the API's: MPI_Comm_restart_rank and MPI_Comm_remove_rank (and MPI_Comm_Irestart_rank, no need for Iremove as it's a local operation) I'll change the sample code to reflect that. Thoughts? Thanks, .Erez

Since right now we're being very explicit about the API, having two calls makes sense. Greg Bronevetsky Post-Doctoral Researcher 1028 Building 451 Lawrence Livermore National Lab (925) 424-5756 [email protected] http://greg.bronevetsky.com
