Abstract
We examine the performance of the molecular dynamics code Parallacs and the time-domain (TD) codes in the General ElectroMagnetic Solvers (GEMS) code suite for a 32 CPUs IBM 1.1 GHz pwr4 node. Parallacs is an easily portable molecular dynamics (MD) benchmark code, which contains most features found in current general-purpose production MD codes. Timings and scaling behavior up to 16 CPUs is reported.
The GEMS TD codes give the expected performance. For large problems, they are three to four times faster on a 1.1 GHz pwr4 node than on a 375 MHz pwr3 node.
