MPS

Abstract

MPS is a parallel numerical code to solve the incompressible magnetohydrodynamics (MHD) equations in a three-dimensional periodic domain. The code was developed at the University of Chicago as part of NASA's High Performance Computing and Communication (HPCC) initiative. It can be used to perform high-resolution numerical studies of MHD turbulence and nonlinear dynamo action in a triply periodic domain. These studies are relevant to the understanding of MHD processes in the outer layers of our Sun, where they are the basic mechanism underlying many observed phenomena, like the 11-year sunspots cycle, and time eruptions of solar flares (Cattaneo 94; Cattaneo et al. 95). MPS is based on the pseudo-spectral transform method and can run efficiently on distributed memory parallel machines with a basic message passing environment. More specifically, it has been optimized for the 512-node CRAY machines at NASA's Goddard Space Flight Center to achieve a performance of over 10 gigaFLOPS on the T3D and 50 gigaFLOPS on the T3E.
