SCIENCE GATEWAYS, AND
Kurt A. Seiffert
• What is the TeraGrid
• Indiana University’s data-centric computing
– 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
– (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)
– 2.6 Kernel (RHEL 4)
• 6 DDN S2A9550 Controllers
– Over 2.4 GB/sec measured throughput each
– 535 Terabytes of spinning SATA disk
• 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?

• SarvamoolaGranthas – teachings of
ShriMadhvacharya (1238-1317) a great
Indian Philosopher, proponent of Dvaita
• SarvamoolaGranthas is a collection of
works with commentaries on various
important scriptures such Vedas,
Upanishads, Itihasas, Puranas, Tantras
• All of the original manuscripts of the
Sarvamoolagranthas were incised on
• Mathas or Monasteries

• 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

• 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,
