Oak Ridge National Laboratory is running the world's largest Cray X1, the world's largest unclassified Cray XT3, and a Cray XD1. In this report we provide an overview of the applications requiring leadership computing and the performance characteristics of the various platforms at ORNL. We then discuss ways in which we are working with Cray to establish a roadmap that will provide 100's of teraflops of sustained performance while integrating a balance of vector and scalar processors.
