Study of transplanting MPI applications in grid environments

Grid computing brings us a new high performance parallel computing solution. This article introduces the concept of grid computing and the use of MPICH-G2, a implementation of MPI in grid environments. It describes the significations to tranplant MPI applications into globus grid. An example of the mesoscale numerical weather prediction model MM5 is presented, and the test result is attached and analyzed. Finally, a conclusion is brought forward.
