  2. SCIENCE - TERAGYROID • Project couples cutting-edge grid technologies, high-performance computing, visualization and computational steering capabilities to produce a major advance in soft condensed matter simulation • Interesting effects only for particular parameter values. Use TeraGrid and UK Reality Grid to generate many small computations, then migrate interesting ones to large systems, like PSC’s TCS. PSC contributions: Led effort to organize and execute the TeraGyroid project Enabled largest Boltzmann lattice calculation ever (10243)

  3. TECHNOLOGY End-to-end Application Performance Use PSC-developed network/host tuning capabilities (Web100, Net100) • Cray XT3 • Leadership class computing • Novel technology for extraordinary scalability • Distinguishing feature- huge inter-processor bandwidth • Lustre file system • Candidate for TeraGrid global file system

  4. SYNERGYSTIC ACTIVITIES CELLSIMULATIONS(NIH-funded) Large-scale cellular simulations Needs ability to launch, manage, and integrate results from 1000’s of independent runs MCELL- Co-author Joel Stiles, PSC

  5. TECHNOLOGY SCALING TCS “LeMieux” at PSC: Reliably Providing Thousands of Processors Per Job

  6. SCIENCE 3/4 TORNADO WARNINGS ARE FALSE ALARMS Most Realistic Tornado Simulation Ever Done Will Reduce Tornado False Alarms K. Droegemeier and M. Xue Wind speed up to 260 mph 25 meter horizontal resolution 20 meter vertical resolution 2048 TCS processors for 24 hours Generated 20 TB data
