Parallel Rendering && VisIt InfrastructureParallel Rendering && VisIt Infrastructure
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

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

Future Work
• Parallel VisIt GPU access (2.1)• Multiresolution in VisIt• BTS• CI improvements• Infrastructure: Plot OpenGL use (2.1)• GLEW v2?• VisIt/Tuvok (2.2?)• Long term: tiled rendering?
