Post-processing and visualization are key components to understanding any simulation. Porting ParaView, a scalable visualization tool, to the Cray XT3 allows our analysts to leverage the same supercomputer they use for simulation to perform post-processing. Visualization tools traditionally rely on a variety of rendering, scripting, and networking resources; the challenge of running ParaView on the Lightweight Kernel is to provide and use the visualization and post-processing features in the absence of many OS resources. We have successfully accomplished this at Sandia National Laboratories and the Pittsburgh Supercomputing Center.

As the deadline to the paper approached, we were still running performance measurements on Pittsburgh Supercomputer Center's Bigben Cray XT3 computer. We did not have time to put them in the paper, but here is summary of some metrics taken directly from the functional units that ran during the visualization. All measurements are given in seconds.
