....we expect that a newer operating system that supports communication from multiple processors per node in User Space will have been implemented in the production environment. We expect to report on the programming paradigm comparison at that time. 5 The SPPM Hydrodynamics Code The SPPM code [4] is a simpli ed version of the Piecewise Parabolic Method (PPM) Code mentioned above. It solves the single uid compressible Navier Stokes equations in three dimensions using the piecewise parabolic method, which is a higher order accurate Godunov method developed by Colella and Woodward [5] The ....

....do vector vector operations, Level 2 BLAS do matrix vector operations, and Level 3 BLAS do matrix matrix operations. Because the BLAS are efficient, portable, and widely available, they are commonly used in the development of high quality linear algebra software, such as LAPACK [1] and ScaLAPACK [2], for example. In general, the existing BLAS have proven to be very effective in facilitating the production of portable, efficient software for sequential, vector and shared memory high performance computers. However, hand optimized BLAS are expensive and tedious to produce for any particular ....

.... its development phase, is an outgrowth of the earlier volume renderers perpath (a serial, in core, software volume renderer) and Bob (an interactive extension of perpath for which both software and SGI texture hardware versions exist) which were also developed at the University of Minnesota [9]. HVR is a highly ecient volume renderer which runs on, and fully utilizes, the texture hardware on SGI In nite Reality Engine computers and which has additional special enhancements that enable it to make volume renderings at unprecedented graphical and data resolutions. These enhancements ....

....bubble and spike, indicating that the coupling of long and short scales has destroyed most of the short wavelength bubbles and spikes. 6. 2 Compressed dump postprocessing The compressed dumps are designed to be postprocessed by a3d, another member of the PPM Data Analysis and Rendering Toolkit [9]. A3d, which has been recently generalized to work in parallel and for large data sets, may be used to calculate any combination of algebraic, di erential or integral forms on the raw data. The elds so produced may be output in the form of histograms, power spectra, cuts through the data, or ....

....yet not overly dissipate the smooth ow. The work presented here deals with the numerical simulation of compressible threedimensional ows with shocks, using spatial resolutions never before considered feasible. We utilize the simpli ed Piecewise Parabolic Method (sPPM) code of Woodward, et al. [1] on the IBM SP Sustained Stewardship TeraOp (SST) machine at Lawrence Livermore National Laboratory (LLNL) We rst present a proof of principle calculation that executed at a sustained 1.05 T op s rate for over an hour. We then present a shorter proof ofprinciple test that, using a modi ed ....
