The coordinated use of geographically distributed computers, or metacomputing, can in principle provide more accessible and cost-e ective supercomputing than do conventional highperformance systems. However, we lack evidence that metacomputing systems can be made easily usable or that large numbers of applications are able to exploit metacomputing resources. In this article, we present work that addresses both these concerns. The basis for this work is a system called Nimrod that provides a desktop problemsolving environment for parametric experiments. We describe how Nimrod has been extended to support the scheduling of computational resources located in a wide-area environment and report Proceedings of the 20th Australasian Computer Science Conference, Sydney, Australia, February 5{7 1997. on an experiment in which Nimrod was used to schedule a large parametric study across the Australian Internet. The experiment provided both new scienti c results and insights into Nimrod capabilities. We relate the results of this experiment to lessons learned from the IWAY distributed computing experiment and draw conclusions as to how Nimrod and I-WAY{like computing environments should be developed to support desktop metacomputing.
