The core algorithm of the code is the conjugate gradient method used to solve the pressure equation. For good performance, a low latency and high bandwidth is required and the results indicate that, without substantial investment in this area, neither system is competitive on parallel performance when compared to more traditional distributed memory machines. At present, they are very suitable for development platforms and, for particular applications that are not too sensitive to latency and bandwidth, they offer a very cost effective computing resource.

As processing elements, operating systems, and switch technology become cheap commodity parts, building a powerful supercomputer at a fraction of the price of a proprietary system becomes realistic. We have recently purchased, in support of both our local and national collaborations, a dedicated computational cluster of eight DEC Alpha workstations.
