Programming with MPI Communicators etc.: Transcript

NickMaclarenComputingService nmm1camacuk May2008 ProgrammingwithMPI. Ticket #273. Introduction. I/O is . one . of the main bottlenecks in HPC applications.. Many applications or higher level libraries rely on MPI-I/O for doing parallel I/O.. Several optimizations have been introduced in MPI-I/O to meet the needs of application. Junchao. Zhang.
