11 TeraGrid Science Highlights 2007

12 Cosmology Tiziana di Matteo, Carnegie Mellon U Gas density is shown (increasing with brightness) with temperature (increasing from blue to red color). Yellow circles indicate black holes (diameter increasing with mass). At about 6 billion years, the universe has many black holes and a pronounced filamentary structure. Found that black holes regulate galaxy formation. As they swallow gas, they radiate so much energy, they stop the inflow of gas. Worked with PSC to improve scaling and use hybrid MPI-shared memory programming for GADGET.

13 Arterial Tree Simulation and Visualization Brown University, Northern Illinois University, and University of Chicago/Argonne National Laboratory Blood flow visualization demonstration at SC07 Simulation runs across multiple TeraGrid sites Computation: NCSA: 256 processors UC/ANL: 64 processors SDSC: 128 processors SDSC: 144 processors Total: 592 processors Data transfer from compute to visualization site (GridFTP) UC/ANL: 4 processors Visualization UC/ANL: 16 processors SC07 Exhibit floor

14 Storm prediction Ming Xue, U. of Oklahoma Better alerts for thunderstorms, especially supercells that spawn tornados, could save millions of dollars and many lives. Unprecedented experiment, every day from April 15- June 8 (tornado season) to test the ability of storm- scale ensemble prediction under real forecasting conditions for US east of the Rockies. First time for –ensemble forecasting at storm scale –real-time in a simulated operational environment Successful predictions of the overall pattern and evolution of many of the convective-scale features, sometimes out to the second day, and good ability to capture storm-scale uncertainties Top: prediction 21 hours ahead of time for May 24, 2007 ; Bottom: observed.

15 Protein Structure David Baker, U. of Washington David Baker’s Rosetta code has proved the best at predicting protein 3-D structure from sequence in biannual competitions (CASP- Critical Assessment of Structural Predictions) Used 1.3 M hours on NCSA Condor to identify promising targets, then refined 22 promising targets on 730,000 hours of SDSC Blue Gene. SDSC helped improve scaling to run on 40,960 processor BlueGene at IBM, which reduced the running time for a single prediction to 3 hours, instead of weeks on a typical 1,000 processor cluster. Protein structure prediction by the Rosetta code, showing the predicted structure (blue), the X-ray structure (red), and a low-resolution NMR structure (green).

16 Solve any Rubik’s Cube in 26 moves? Rubik's Cube is perhaps the most famous combinatorial puzzle of its time. > 43 quintillion states (4.3x10^19) Gene Cooperman and Dan Kunkle of Northeastern Univ. just proved any state can be solved in 26 moves. 7TB of distributed storage on TeraGrid allowed them to develop the proof URL:

17 TeraGrid Web Resources TeraGrid User Portal for managing user allocations and job flow Knowledge Base for quick answers to technical questions User Information including documentation, information about hardware and software resources Science Highlights News and press releases Education, outreach and training events and resources TeraGrid Provides a rich array of web- based resources: In general, seminars and workshops will be accessible via video on the Web. Extensive documentation will also be Web-based.

18 Science Gateways Broadening Participation in TeraGrid Increasing investment by communities in their own cyberinfrastructure, but heterogeneous: Resources Users – from expert to K-12 Software stacks, policies Science Gateways –Provide “TeraGrid Inside” capabilities –Leverage community investment Three common forms: –Web-based Portals –Application programs running on users' machines but accessing services in TeraGrid –Coordinated access points enabling users to move seamlessly between TeraGrid and other grids.
