NCAR Teragrid RP Developments• Current Cyberinfrastructure

– 5.7 TFlops/2048 core Blue Gene/L system– 100 TB storage cluster – 1.5 PB SL8500 Tape archive with 1 PB media running HPSS/HSI– Sun DAV visualization node– Chronopolis data preservation testbed

• New Cyberinfrastructure Developments – Possible Blue Gene/L Expansion to 22.8 TF system with 8192 cores– 100 TFLOPS MRI System @ CU with NCAR 10% stakeholder– DAV node upgrade to more capable 8 core system with larger memory– Proposal to expand HPSS Archive to 2.5 PB.

• Science Gateway developments– Asteroseismic Modeling Portal (AMP). Successful launch of the Kepler spacecraft increases potential

scientific impact of this gateway.– Looking at hosting Research Data Archive on HPSS

Using the TeraGrid to Understand the Stars and Search for Planets:

Problem: The oscillations modes of stars give clues to the stellar interior.

• Accurate modeling of these oscillations can tell us the size, composition and age of stars, and in turn help interpret the data returned by NASA’s Kepler Mission in the hunt for Earth-like extrasolar planets.

• Solution: NCAR is working with the international science community to develop a TeraGrid science gateway to fit oscillation data with stellar models to determine these parameters automatically for large numbers of stars.

• Key Elements: international science impact, gateway technology.

The turbulent solar atmosphere captured with NASA’s TRACE

satellite is overlaid with a model of

one of the millions of oscillation modes that allow scientists to

deduce the Sun’s hidden internal structure and dynamics. Similar measurements are now being

made for other solar-type stars.
