Implementation of parallel plasma particle-in-cell codes on SuperSINET based grid

We present our parallel plasma particle-in-cell simulation experiment based on a computation grid system on the high performance network SuperSINET. This computation grid system consists of three supercomputer nodes on SuperSINET configured with the Globus Toolkits andMPICH-G2. In our experiments, we first confirm the scalability of the parallel PIC simulation code on this computational grid. After we analyze the results and find that the bottleneck point exist on communication across the network, we successfully make use of some useful features of Globus and MPICH-G2 architecture to improve communication efficiency across the network
