| Zusammenfassung: | Abstract: "After a brief introduction in multigrid methods we discuss some of the algorithmic choices in MGZEB, a parallelized highly vectorized multigrid code for the solution of linear systems resulting from the 7-point discretization for general linear second order elliptic PDEs in two dimensions. We describe the minimization of the scalar operation count, the vector tuning on a vector-register machine and the parallelization of the already existing highly vectorized MGZEB code. At present we would use the same algorithm with the same scalar operation count on a scalar uni-processor. Finally, we discuss the overall parallel vector-performance using autotasking on a Cray Y-MP4/464." |
