“…The team demonstrated that a computation running on the Pittsburgh Supercomputer could be steered from a notebook computer on the show floor in Seattle (Woodward et al 2007). From this notebook, users could start, pause, and restart a computation as well as modify the input parameters on demand.…”

The current availability of thousands of processors at many high performance computing centers has made it feasible to carry out, in near real time, interactive visualization of 3D mantle convection temperature fields, using grid configurations having 10-100 million unknowns. We will describe the technical details involved in carrying out this endeavor, using the facilities available at the Laboratory of Computational Science and Engineering (LCSE) at the University of Minnesota. These technical details involve the modification of a parallel mantle convection program, ACuTEMan; the usage of client-server socket based programs to transfer upwards of a terabyte of time series scientific model data using a local network; a rendering system containing multiple nodes; a high resolution PowerWall display, and the interactive visualization software, DSCVR. We have found that working in an interactive visualizastion mode allows for fast and efficient analysis of mantle convection results.

SUMMARYWe report initial experience with gas dynamics simulation on the Los Alamos Roadrunner machine. In this initial work, we have restricted our attention to flows in which the flow Mach number is less than 2. This permits us to use a simplified version of the PPM gas dynamics algorithm that has been described in detail by Woodward (2006). We follow a multifluid volume fraction using the PPB moment-conserving advection scheme, enforcing both pressure and temperature equilibrium between two monatomic ideal gases within each grid cell. The resulting gas dynamics code has been extensively restructured for efficient multicore processing and implemented for scalable parallel execution on the Roadrunner system. The code restructuring and parallel implementation are described and performance results are discussed. For a modest grid size, sustained performance of 3.89 Gflop s −1 CPU-core −1 is delivered by this code on 36 Cell processors in 9 triblade nodes of a single rack of Roadrunner hardware.

SUMMARYWe have designed a web-based software system for real-time interactive visualization of results taken from large-scale simulations of 3-D mantle convection and other large-scale modeling efforts. This approach allows for intense visualization sessions for a couple of hours as opposed to storing massive amounts of data in a storage system. Our data sets consist of 3-D data with over 10 million unknowns at each time-step to be used for volume rendering. Large-scale interactive visualization on a display wall holding 15 million pixels has already been accomplished. With the advent of the age of the mobile web, we have now extended this tactic to hand-held devices, such as the OQO, Nokia N800, netbooks, iPHONE, and Android OS phones. We are developing web-based software in Java to extend the ubiquitous use of this system across long distances. The software is aimed at creating an interactive and functional application capable of running on multiple browsers by taking advantage of two AJAX-enabled web frameworks: Echo2 (http://echo.nextapp.com/site/echo2) and Google Web Toolkit (http://code.google.com/webtoolkit/). Modular building of the system allows for components to be swapped out so that other forms of visualization can be accommodated, such as molecular dynamics in mineral physics or 2-D data sets from the regional convection models.
