nanoHUB.org: Cyberinfrastructure for Research and Education

  1. 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. 2. What is nanoHUB? Online simulation… …and more!
  3. 3. Demo Demo >>
  4. 4. Over 50 tools online! 50 more in the pipeline
  5. 5. Web-enabling Tools Vendor Scientist Web Developer
  6. 6. System Architecture Physical Machine Maxwell’s Virtual Machine Content Daemon Database 0101 1011 1001 nanowire job nanoHUB cluster Rendering Farm Violin nanoVIS
  7. 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. 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. 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. 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. 11. A A global following 50% in US
  12. 12. A A global following
  13. 13. Strong growth Online simulation… …and more! Interactive tools Added seminars, tutorials, courses, etc.
  14. 14. nanowire Usage Statistics Released May 19, 2006 656 Users 6,711 Simulations
  15. 15. Saumitra Mehrotra Univ. of Cincinnati In the past 10 months: 26 tools / 3,327 simulations • 47 simulations: bandstructure lab • 240 simulations: FETtoy • 2,855 simulations: nanowire • 8,242 nanowire CPU hours • “and more” content 134 items, 52 hours • 96 support tickets 69 entered manually, 27 filed automatically by application
  16. 16. IEEE Workshop on Microelectronics and Electron Devices (WMED), April 20 2007
  17. 17. Google Scholar finds 159 citations to nanoHUB
  18. 18. Case in point Rappture version Feb 06 366 Users TCAD simulations using SCHRED [15] or Last 12 months ISE, …., were used to support our analysis and compute the inversion carrier profiles in the devices. Effect of channel positioning on the 1⁄ f noise in silicon-on-insulator metal-oxide-semiconductor M von Haartman, M Oestling, Journal of Applied Physics, 2007 - link.aip.org... • Same behavior across all similar converted tools • User’s don’t have to download/install software
