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:

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 Vcycle 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.
