Research Abstract
Dr. Scherson's research interests fall in the general areas of distributed and parallel processing, computer architectures for high performance systems, resource management in and applications of concurrent computation. His research group is currently working on several main subjects: networking, interconnection networks, performance evaluation, and parallel algorithms, numerical and non-numerical.

The main goal of the work on interconnection networks for massively parallel systems is the development of cost-effective high performance networks capable of supporting thousands or millions of processing elements. Included in this study is the performance analysis of Expanded Delta Networks (EDNs) and Least Common Ancestor Networks (LCANs) under commonly occurring sets of processor to processor communication patterns. As a result of the effort, efficient off-line routing algorithms for EDNs were developed and applied to commercially available massively parallel computers.

Current research in performance evaluation deals with the development of models and methodologies for a general supercomputer performance evaluation theory. Such methods are being developed bottom up by building on known computational models and benchmarks.

Algorithmic topics include parallel models of computation and numerical algorithms which can take advantage of asynchronous parallel systems. Additionally, based on the development of Shearsort, Dr. Scherson and his group are looking for a proper taxonomy of parallel sorting. Many similarities can be found among sorting techniques and a unified framework is needed to enable further advances in this important area of study.
