I am working on a project to port a 2d mixed finite-difference
spectral code from the CRAY YMP to a CM-II. The bottlenecks of
the code involve two-dimensional FFT's (nx one-dimensional FFT's
on vectors of length ny), in which products of fields are
evaluated by the pseudospectral methods, and solution of pentadiagonal
banded matrices (nx matrices of size ny x ny where each square
matrix is band 5).

I would greatly appreciate any code or references or both that
would help me in this port. If there is interest, I will summarize
to the net.

	Thanks,

	James Kittock

P.S. nx and ny are expected to be of order 256 to 1024 in size.
