The Impact of Parallel Programming Models on the Linear Algebra Performance for Finite Element Simulations
Kengo Nakajima (The University of Tokyo)
Abstract:
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.
