  1. Parallel Rendering && VisIt Infrastructure Tom Fogal www.vacet.org

  2. Impact • Infrastructure projects • Efficient parallel rendering in VisIt • VisIt infrastructure: process, community outreach • “Basic” infrastructure: wide range of groups • Most applicable: large data • “Too big to move” groups • 20 seconds is too long for volume rendering! • Accelerate it (now) • Other approaches (later) • CI-testing, BTS: all VisIt development www.vacet.org

  3. Back to the Future • Tuvok / VisIt integration • Multi-GPU Distributed Volume Rendering • New Bug tracking system • IceT and related work • GLEW / Mesa issues sorted out (AIX) • GPU – IO paper • VisIt bug fixes affecting above www.vacet.org

  4. Multi-GPU Parallel Volume Rendering www.vacet.org

  5. VisTrails Integration www.vacet.org

  6. Input Needed – Parallel Rendering Chromium SAGE IceT Equalizer www.vacet.org

  7. Future - Multiresolution • Colleague integrated multires operator, DB • Basic implementation now • Expand in this cycle www.vacet.org

  8. Future Work • Parallel VisIt GPU access (2.1) • Multiresolutionin VisIt • BTS • CI improvements • Infrastructure: Plot OpenGL use (2.1) • GLEW v2? • VisIt/Tuvok(2.2?) • Long term: tiled rendering? www.vacet.org

  9. End • Thanks • Cyrus (LLNL) – Mesa/GLEW, buildbot • Jianrong (Utah) – GLEW, particularly win32/GLEW • Hank – IceT interface issues needed for default, paper Questions? www.vacet.org
