This paper describes a unique visualization tool that has been used to analyze performance of the Cplant™ clusters[13] at Sandia National Laboratories. As commodity cluster systems grow in size and complexity, understanding performance issues becomes more and more difficult. We have developed a tool that facilitates visual performance analysis within the(More)
This paper presents a novel use of visualization applied to debugging the Cplant™ cluster hardware at Sandia National Laboratories. As commodity cluster systems grow in popularity and grow in size, tracking component failures within the hardware will become more and more difficult. We have developed a tool that facilitates visual debugging of errors(More)
As access to multi-teraflop platforms has become more available in the Department of Energy Advanced Simulation Computing (ASCI) environment, large-scale simulations are generating terabytes of data that may be located remotely to the site where the data will be archived. This paper describes the Data Service Archive (DSA), a service oriented capability for(More)
