Integration of parallel MM5 with distributed resource manager and performance evaluation

The PSU/NCAR mesoscale model (known as MM5) is a limited-area, nonhydrostatic, terrain-following sigma-coordinate model designed to simulate or predict mesoscale atmospheric circulation. MM5 is popularly used in numerical weather prediction and each simulation runs can take from several minutes to many hours. In many datacenters today, it is common that distributed resource management (DRM) software like LSF, PBSPro and N1 grid engine are employed to manage and optimize compute resources. In this paper, we described our experience of integrating parallel MM5 with N1 grid engine (N1 GE), and discussed some of its performance characteristics. Our work shows that the integration parallel MM5 with distributed resource managers is feasible and the performance is rather good.
