PARKBENCH PDE KERNEL BENCHMARK

In the PDE kernel, communication is basically exchange with neighbors and the convergence check is a reduction. A variety of methods and update stencils may be used. The following PDE solver is included in the parallel benchmark suite:

  1. Multigrid kernel. The PARKBENCH multigrid kernel is the multigrid benchmark from the NAS Parallel Benchmark suite. It requires highly structured long distance communication and tests both short and long distance data communication. The kernel performs a V-cycle multigrid algorithm to obtain an approximate solution of a discrete Poisson problem on a 256 by 256 grid with periodic boundary conditions.
This kernel may be obtained in the current distribution from the netlib repository.
