AbstractOne of the primary obstacles users face in Grid computing is that Grids are typically composed of many diverse resources, while applications require a very specific, customized environment to run in. Many applications are dependency-rich and complex, making it hard to run them on anything but a dedicated platform. Worse, even if the applications do run there, the results they produce may not be consistent across different runs. As part of the Center for Enabling Distributed Petascale Science (CEDPS) project we have been developing the Workspace service which allows authorized Grid clients to dynamically provision environments in the Grid. Virtual machines provide an excellent implementation of a portable environment as they allow users to configure an environment and then deploy it on a variety of platforms. This paper describes a proof-of-concept of this strategy developed for the High-Energy Physics STAR application. We are currently building on this work to enable production STAR runs in virtual machines.
