The Impact of Parallel Programming Models on the Linear Algebra Performance for Finite Element Simulations
Kengo Nakajima (The University of Tokyo)
Parallel iterative linear solvers for unstructured grids in FEM applications, which were developed for the Earth Simulator (ES), have been ported to various types of parallel computers. Performance of flat-MPI and hybrid par-allel programming model has been compared for ES, Hitachi SR8000, IBM SP-3 and IBM p5-model 595. Effect of coloring and method for storage of coeffi-cient matrices have been also evaluated in various types of applications. Per-formance with more than 10^4 processors has been estimated using measured data up to 10^3 processors.
