Abstract
Parallel iterative linear solvers for unstructured grids in FEM applications, originally developed for the Earth Simulator (ES), are ported to various types of parallel computer. The performance of flat MPI and hybrid parallel programming models is compared for the ES, Hitachi SR8000, IBM SP-3 and IBM p5-model 595 supercomputers. The effect of coloring and of different storage methods for coefficient matrices are evaluated in various types of application. Performance for more than 104 processors is estimated using measured data for up to 103 processors.
