Hello, I am wondering if anyone knows of a parallel direct solver package for Poisson's equation on Cartesian grids. I am looking for something similar to the Fiskpack package, but capable of being run on distributed parallel machines. One alternative, of course, is to build one myself based on a parallel implementation of FFTs, but that takes time...

Thanks, Frank

search for code called Aztec by sandia national labs. They have a parallel sparse matrix solver.
