Comparing Linux Clusters for the Community Climate System Model
Overview In this paper, the authors examine the performance of two components of the NCAR Community Climate System Model (CCSM) executing on clusters with a variety of microprocessor architectures and interconnects. Specifically, the authors examine the execution time and scalability of the Community Atmospheric Model (CAM) and the Parallel Ocean Program (POP) on Linux clusters with Intel Xeon and AMD Opteron processors, using Dolphin, Myrinet, and Infiniband interconnects, and compare the performance of the cluster systems to an SGI Altix and an IBM p690 supercomputer. Of the architectures examined, clusters constructed using AMD Opteron processors generally demonstrate the best performance, outperforming Xeon clusters and occasionally an IBM p690 supercomputer in simulated years per day.
