| Abstract: | Abstract: "The Numerical Multigrid Software FORTRAN routines MGD1M and MGD5M, multitasked successors of MGD1V and MGD5V are described. General techniques to improve the (vector) performance on the CRAY Y-MP, which are also suitable for other high-performance machines have been applied. Parallelism has been introduced by applying auto- and macrotasking. MGD1M solves 7-diagonal linear systems, that arise from 7- point discretizations of elliptic PDEs on a rectangle, using a multigrid technique with ILU relaxation as smoothing process. A straightforward ILU implementation leads to non-vectorizable recursive relations. By applying an alternative ordering of the grid points, the ILU relaxation vectorizes and the overall execution time is reduced considerably. MGD5M solves 7- diagonal linear systems, that arise from 7-point discretizations of elliptic PDEs on a rectangle, using a multigrid technique with Incomplete Line LU(ILLU) relaxation as smoothing process. The ILLU relaxation has been partly parallelized on the finest grid by performing a twisted LDU- decomposition." |
