  1. Overview of theHUBzero Platform Michael McLennanSenior Research Scientist and Hub Software Architect Rosen Center for Advanced ComputingPurdue University

  2. Why Cyberinfrastructure?

  3. Cyberinfrastructure = HUB Online simulation… …and more! HUB

  4. What is a HUB? Example: nanoHUB.org Demo: AVIMOVYouTube

  5. nanoHUB.org Usage Statistics 105,000 users worldwide >5,000,000 hits/month All Top 50 US Engr Schools 14% of all .edu domains333 International Ed Institutions 233 US K-12 schools

  6. Platform for Scientific Collaboration “YouTube” for simulationand modeling tools Little bit of social networking: e.g., Questions & Answers Web Server Physical Machine Secure execution environment Maxwell’s Daemon Virtual Machine Virtual economy for incentives and managing resources Tools powered by Grid infrastructure Integrated visualization
