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 Digitization of ““SarvamoolaGranthasSarvamoolaGranthas””

• 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 ManuscriptsShri Madhvacharya

Digitization of Digitization of ““Sarvamoola GranthasSarvamoola 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

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
