  2. Liquid Rocket Combustion Instability Analysis with Coaxial Injector Modeling • PI Heister (PU) ;TG Embed Kim (NCSA) • Completed 03/31/06 • Shear/Swirl coaxial injector modeling enabled. Designed TeraGrid portal framework. • Used DTF (NCSA+SDSC) • The TeraGrid will allow the model’s user community to launch realistic what-if simulations on many systems, including migration of jobs from one system to another.

  3. CMS on the TeraGrid • PI Newman (Caltech) TG Embed Milfeld (TACC) • Ongoing to 9/30/06 • Completing the Physics Technical Design Report for the CMS experiment at LHC • Complex workflow consisting of multiple execution stages running thousands of serial jobs via GridShell on DTF and Lonestar, very large datasets stored on SDSC HPSS and staged to execution sites prior to job runs. • Winner, CLADE 2006 Best Paper “

  4. ENZO: Cosmic Simulator • PI Norman (UCSD) TG Embed Harkness (SDSC) • Completed 3/31/06 • Largest-ever simulations of metal enrichment and turbulent shock fronts in intergalactic matter. Pioneering AMR run sets stage for design verification of Large Scale Synoptic Telescope. • Generated approx. 100 TBytes on DTF, DataStar, Cobalt, TCS. Transferred to SDSC digital library via GridFTP, DMOVER and GPFS_WAN.

  5. Simulated Pore Interactive Computing Experiment • PI Coveney (UCL) • TG Lead O’Neal (PSC) • Completed 3/31/06 • WINNER, SC05 HPC ANALYTICS CHALLENGE • Understand the translocation of biomolecules across protein pores by interactive Molecular Dynamics simulations including haptic devices to get an estimate of force values & to determine suitable constraints to place. • Checkpoint and cloning of simulations to TG systems: TCS, DTF, Lonestar. • Real time visualization at UC/ANL

  6. Web Based Distributed Computing Environment for Nanotechnology • PI Jakobsson (UIUC), TG Embed Parker (NCSA) • Completed 3/31/06 • A simulation portal and data archiving service built on top of Grid services • Used DTF, Tungsten Small molecule channel

  7. PI Brady (Cornell), TG Embed Chukkapali (SDSC) Completed 3/31/06 Enhanced parallel CHARMM to simulate >800K atoms Used IBM P665, P690, DTF to make significant progress in understanding enzymatic breakdown of cellulose. Fuel From Plants -- NREL

  8. Cross-Site Runs and Computational Steering on the TeraGrid • PI Karniadakis (Brown), TG Embed O’Neal (PSC) • Completed 3/31/06 • Enables simulations of the full human arterial tree by a novel, latency hiding algorithm. • Detailed 3D simulations at arterial bifurcations conducted across DTF, TCS, Lonestar using mpich-G2, with Real-Time Visualization at UC/ANL.

  9. CyberShake • PI Olsen (SDSU) / David Okaya (USC), TG Embeds Cui (SDSC), Reddy (GIG/PSC) • Largest and most detailed earthquake simulation of the southern San Andreas fault, • First calculation of physics-based probabilistic hazard curves for Southern California using full waveform modeling rather than traditional attenuation relationships, • So far used DTF and DataStar; WAN-GPFS, GridFTP, CondorG, and RLS. • Workflow tools enable work at a scale previously unattainable by automating the very large number of programs and files that must be managed. Major Earthquakes on the San Andreas Fault, 1680-present 1906 M 7.8 1857 M 7.8 1680 M 7.7 Continuing until 3/31/07 large-scale simulation of a magnitude 7.7 seismic wave propagation on the San Andreas Fault, generating more than 47 TBs of output
