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
