  1. Deploying a Petascale-Capable Visualization and Analysis Tool April 15, 2010

  2. Purpose of the next three talks • Detail the VACET activities to deliver a petascale-capable tool to the Office of Science community (and others) • Ensuring S/W is capable of processing tomorrow’s data • Ensuring that S/W scales (Joule) • Software engineering & deployment • Providing infrastructure to support the community • Outreach to the community

  3. VisIt: Delivering a petascale-capable visualization and analysis tool to the Office of Science, the DoE, and more • Problem • Office of Science application scientists need tools for visualization and analysis (exploration, confirmation, & communication) • Solution • VACET has extended VisIt to deal with unique Office of Science problems, including data size, and deployed to the community • This includes data with trillions of cells using 10K’s cores • Impact • Many Office of Science simulation codes now use VisIt. 11 letters of support from SciDAC-funded groups for VACET review • Large capability delivered in a cost effective manner GNEP/NEAMS choose VisIt due to VACET leadership VACET enables VisIt to run on trillions of cells and 10K’s cores Project started VACET enables multi-institution development APDEC retires ChomboVis for VisIt. Repurposes $’s for math VisIt becomes first ever non-simulation Joule code. Both NSF XD centers commit to supporting VisIt SW repository has ~30 developers from >10 institutions 2000 2005 Fall 2006 2007 2008 2010 2008 Summer 2009 Fall 2009

  4. We studied isocontouring and volume rendering, looking at up to 4T cells. Visualization of 1 trillion cells, visualized with VisIt on Franklin using 16,000 cores. Visualization of 2 trillion cells, visualized with VisIt on JaguarPF using 32,000 cores.

  5. We demonstrated that VisIt performs well on tens of thousands of cores with trillions of cells. • Goal was to uncover bottlenecks on tomorrow’s data. • Experiments varied over supercomputing environment, data generation patterns, and I/O pattern.

  6. Outreach • We have worked hard to deploy VisIt, through tutorials, user support, documentation, etc. • Tutorials:
