The Legion project at the University of Virginia is an architecture for designing and building system services that provide the illusion of a single virtual machine to users, a virtual machine that provides both improved response time via parallel execution and greater throughput. Legion targets workstation clusters and larger wide area assemblies of workstations, supercomputers, and parallel supercomputers. We have built a working Legion prototype, called the Campus-Wide Virtual Computer

In this paper, we describe the challenges that we overcame to realize a working CWVC, and we characterize the performance of a production biochemistry application.
