Q&A with Donald Frederick of the NCCS

June 30 -- The Cray XT Jaguar, the world's fastest computer for open research with a peak performance at 1.6 quadrillion calculations per second (or petaflops) and more than 150,000 processors, is a cutting-edge resource for scientists. Jaguar is operated by the National Center for Computational Sciences (NCCS) at Oak Ridge National Laboratory (ORNL), but scientists can use the system from their home research institutions. Through the Innovative and Novel Computational Impact on Theory and Experiment, or INCITE, program, in 2008, the U.S. Department of Energy allocated processing time to 38 scientific research projects that require Jaguar's speed to solve complex problems ranging from the mysteries of protein folding to the somewhat unpredictable physics of fusion.

Most scientists who are allocated time on Jaguar have some knowledge of parallel computing -- computing with many processors -- but they still have questions about how to effectively use supercomputers with thousands to hundreds of thousands of processors. The NCCS offers workshops for users of high-performance computing systems to acclimate them to Jaguar's mammoth scale and the way the center as a whole functions.

We asked Donald Frederick, NCCS training coordinator for high-performance computing, to discuss such workshops and what they offer Jaguar's users.
