The New Multidevice Architecture of MetaMPICH in the Context of Other Approaches to Grid-Enabled MPI

摘要

MetaMPICH is an MPI implementation which allows the coupling of different computing resources to form a heterogeneous computing system called a meta computer. Such a coupled system may consist of multiple compute clusters, MPPs, and SMP servers, using different network technologies like Ethernet, SCI, and Myrinet. There are several other MPI libraries with similar goals available. We present the three most important of them and contrast their features and abilities to one another and to MetaMPICH. We especially highlight the recent advances made to MetaMPICH, namely the development of the new multidevice architecture for building a meta computer.
