Research Seminar - December 01, 2000

Seminar Announcement


Title: Cluster Computing Architectures and Applications
Speaker: Paul D. Coddington
  Distributed and High-Performance Computing Group
Department of Computer Science
Adelaide University
Date: Friday 1st December, 2000
Time: 12.00pm
Venue: Seminar Room 1.24

Abstract

Over the past few years, clusters of networked computers have become very popular as a low-cost alternative to traditional supercomputers. The dramatic improvements in performance (and more importantly, the ratio of price/performance) of commodity PCs, workstations, and networks have made clusters of off-the-shelf computers an attractive option for low-cost, high-performance computing, particularly for scientific applications.

The Distributed and High-Performance Computing Group at Adelaide University has been working with computational scientists in chemistry, physics and engineering on planning, proposal development, and procurement of two large compute clusters which were installed in the past year. Both of these machines have a peak performance of over 100 GFlops, making them among the fastest supercomputers in Australia.

In this talk I will give an overview of cluster computing, and describe the architecture of the two machines at Adelaide: a home-made commodity PC (or Beowulf) cluster, and a commercial cluster from Sun Microsystems. I will also discuss work on benchmarking of the machines, and the porting and performance of some parallel application codes.
