Abstract

We introduce a parallelization of the maximum-likelihood cosine transform.This transform consists of a computationally intensive iterative fittingprocess, but is readily decomposed for parallel processing. The parallelimplementation is not only scalable, but has also brought the execution time of this previously intractable problem to feasible levels using contemporary and cost-efficient high-performance computers, including the SGI Origin 2000, SGI Onyx, and a cluster of Pentium PCs.
