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)
– 2.6 Kernel (RHEL 4)
• 6 DDN S2A9550 Controllers
– Over 2.4 GB/sec measured throughput each
– 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
• Life Science
• High Energy Physics

Digitization of
“SarvamoolaGranthas”
•
•
•
•
Shri Madhvacharya
SarvamoolaGranthas – teachings of
ShriMadhvacharya (1238-1317) a great
Indian Philosopher, proponent of Dvaita
Philosophy
SarvamoolaGranthas is a collection of
works with commentaries on various
important scriptures such Vedas,
Upanishads, Itihasas, Puranas, Tantras
and Prakaranas
All of the original manuscripts of the
Sarvamoolagranthas were incised on
palm leaves
Mathas or Monasteries
– Keepers of Palm Leaf Manuscripts
Digitization of
“Sarvamoola
Granthas”
Post processed images of the palm leaves
Sample images of the palm leaf of Sarvamoola granthas illustrating the
performance of the image processing algorithms. (a) Stitched 8 bit grayscale
image without normalization and contrast enhancement, (b) Final image after
contrast enhancement

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…)

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
