  • 1. nanoHUB.org: Cyberinfrastructure for Research and Education Michael McLennan Software Architect Network for Computational Nanotechnology Purdue University Cyberinfrastructure Summit: Innovation at Work Banff, AB, October 11-12, 2007
  • 2. What is nanoHUB? Online simulation… …and more!
  • 3. Demo Demo >>
  • 4. Over 50 tools online! 50 more in the pipeline
  • 5. Web-enabling Tools Vendor Scientist Web Developer
  • 6. System Architecture Physical Machine Maxwell’s Virtual Machine Content Daemon Database 0101 1011 1001 nanowire job nanoHUB cluster Rendering Farm Violin nanoVIS
  • 7. Rappture Toolkit Rappture = Simulation • Created by NCN in Nov 2004 Code • Create standard desktop apps • Works with your favorite programming language • Open Source • Online at http://rappture.org Scientist
  • 8. Rappture works by defining the interface XML interface description <?xml version=quot;1.0quot;?> <run> <tool> <title>Name of the tool</title> <about>Description and credits</about> <command> @tool/path/to/executable @driver </command> <limits> <cputime>900</cputime> <filesize>1000000</filesize> </limits> </tool> <input> ... </input> <output> ... </output> </run> integer: n curve: E-k diagram CNTbands integer: m curve: DOS model choice: sim method molecule: structure … …
  • 9. Inputs, Outputs, and Metadata Complete record of every simulation run <?xml version=quot;1.0quot;?> <run> <tool> <title>CNTbands v2.0</title> <command>@tool/cnbandswr @driver</command> Exact software <version> revision from <application> <revision>16</revision> Subversion <modified>2007-05-24 10:58:42 EDT</modified> <installed>2007-05-24 10:59:51 EDT</installed> More details </application> about software </version> </tool> installation <input> </input> All inputs <output> </output> All results </run>
  • 10. Who’s using this? 2.5 million hits last month 26,196 users last 12 months 226,899 simulation jobs last 12 months 51 of the Top 50 Engineering Schools 11.75% of all .edu domains
  • 11. A A global following 50% in US
