MGD1M, a parallel multigrid code with a fast vectorized ILU-relaxation:
Abstract: "In this paper we focus on MGD1M, a multigrid method which uses Incomplete LU-relaxation (ILU) as a smoothing process. A straightforward ILU implementation leads to non-vectorizable recursive relations. By applying an alternative ordering of the grid points, proposed by Ashcraft et al...

| Zusammenfassung: | Abstract: "In this paper we focus on MGD1M, a multigrid method which uses Incomplete LU-relaxation (ILU) as a smoothing process. A straightforward ILU implementation leads to non-vectorizable recursive relations. By applying an alternative ordering of the grid points, proposed by Ashcraft et al.[1], the ILU vectorizes and the overall execution time is reduced considerably. We also consider general techniques to improve the (vector) performance on the Cray Y-MP4, which are also suitable for other high-performance machines. Parallelism has been introduced by applying auto- and macrotasking. Performance results measured on a dedicated Cray Y-MP4/464 are discussed." |
