A series of four benchmark tests were completed during September 22-26, 2003 at the IBM Benchmarking Center in Poughkeepsie, NY. The primary focus of these tests was to evaluate GPFS performance for HPC applications on Linux clusters. The clusters in this test were IBM eServer xSeries 345-based systems using IBM TotalStorage FAStT900 disk controllers and EXP700 disk drawers. Each test was conducted on a different cluster network configuration (Gigabit Ethernet (GbE), bonded GbE, 100 Megabit Ethernet (MbE), and Myrinet). Some of these test configurations are officially supported, and others are not.
