HIGH PERFORMANCE MESSAGE PASSING LIBRARY FOR MAESTRO2 CLUSTER NETWORK

A cluster has become a popular platform for high per-formance computing. Currently, many PC clusters are organized with cost-effective conventional wide-area network technologies to connect each processing elements. Here, it is difficult to extract potential performance of the cluster, since there is the disparity between the wide-area network technologies and the performance characteristics required by cluster computing. We have developed a net-work to build high performance PC cluster, called Maes-tro2 cluster network. This paper describes about high per-formance communication library for Maestro2, named MMP. First, we describe the novel technique, design, and implementation of Maestro2. Then, we present a design and an implementation of MMP. We also show experi-mental results to evaluate the basic performance of MMP and compare it with raw performance of Maestro2. The experimental results show that MMP can extract maxi-mum performance from Maestro2. KEY WORDS cluster computing, high-performance network, message passing library, performance evaluatio
