The ability to quickly do short, exploratory runs of PPM simulations of turbulence will have a significant impact on scientific productivity. The Cray Red Storm machine at the Pittsburgh Supercomputer Center has the potential to compute a relatively small problem, on a grid of just 5123 cells, fast. Previous systems are only able to achieve their best performance on extremely large problems. LCSE demonstrates a prototype computational steering, visualization and data analysis system that will be able to produce volume rendered images from this data at a rate of a few per frames second on its 10-panel PowerWall. Ultimately, data from the complete run, stored on the data archive system at the San Diego Supercomputer Center, will be accessed, compressed and streamed over National LambdaRail for interactive viewing on the PowerWall.
