            Outline Presentation
• What is the TeraGrid
• Indiana University’s data-centric computing
  focus
   – HPSS
   – Lustre
   – Data collections
• Science Gateways
• Bringing it all together
                   What is the TeraGrid?
•   An instrument (cyberinfrastructure) that delivers high-end IT resources -
    storage, computation, visualization, and data/service hosting - almost all of
    which are UNIX-based under the covers; some hidden by Web interfaces
     – A data storage and management facility: over 20 Petabytes of storage (disk
        and tape), over 100 scientific data collections
     – A computational facility - over 750 TFLOPS in parallel computing systems
        and growing
     – (Sometimes) an intuitive way to do very complex tasks, via Science
        Gateways, or get data via data services
•   A service: help desk and consulting, Advanced Support for TeraGrid
    Applications (ASTA), education and training events and resources
•   The largest individual cyberinfrastructure facility funded by the NSF, which
    supports the national science and engineering research community
•   Allocated via peer review (and without double jeopardy)

    What’s A Data Capacitor Really?
• 12 pairs Dell PowerEdge 2950
   – 2 x 3.0 GHz Dual Core Xeon
   – Myrinet 10G Ethernet
   – Dual port Qlogic 2432 HBA (4 x FC)

   – 535 Terabytes of spinning SATA disk
             Bandwidth Challenge
• Annual Event at SC Conference in November
   – This year’s venue - Reno, Nevada
• This Year’s Theme - “Serving as a Model”
   – Can others do what you’re doing?
• Criteria for Judging
   – Did you fill a single 10 Gigabit connection?
   – How are you supporting science?
   – Did you use your production network?
              The Challenge:
     Five Applications Simultaneously
• Acquisition and Visualization
  – Live Instrument Data
     • Chemistry
  – Rare Archival Material
     • Humanities
• Acquisition, Analysis, and Visualization
  – Trace Data
     • Computer Science
  – Simulation Data

               Science Gateways
• A Science Gateway is a domain-specific computing
  environment, typically accessed via the Web, that
  provides a scientific community with end-to-end support
  for a particular scientific workflow
• Science Gateways are distinguished from Web portals
  (http://en.wikipedia.org/wiki/Web_portal) in that portals
  “present information from diverse sources in a unified
  way.”
• Hides complexity (pay no attention to the grid behind the
  curtain…)
        LEAD (portal.leadproject.org)




•   Simple enough an undergraduate can use it!
•   National Center for Supercomputing Applications (NCSA) and IU teamed up to
    support WxChallenge weather forecast competition. 64 teams, 1000 students,
    ~16,000 CPU hours on Big Red
