This directory contains items relating to the numerical solution
of the shallow water equations in spherical geometry.
The shallow water equations are used as a kernel for both
oceanic and atomospheric general circulation models and
are of interest in evaluating numerical methods for weather
forecasting and climate modeling. The DOE Computer Hardware,
Advanced Mathematics and Model Physics (CHAMMP) program
is interested in the development of new mathematical methods
for these problems. To promote this developmet, a set of
test cases has been proposed and example software and reference
solutions are provided.

• file: pstswm.tgz
  for: Parallel version of stswm for message passing parallel computers. Contains a variety of parallel algorithms implementing the spectral transform method. Code useful for comparison of parallel algorithms: transpose vs. transform, overlapped vs. nonoverlapped communication, etc. Uses PICL for portability.
