Computational Research in Balance with NERSC Center • A organizational balance between production facility and research activities is essential for the success of both • the NERSC Center benefits directly from the DOE funded computer science research project • the requirements of the NERSC Center stimulate computer science research and keep it closely relevant to the DOE mission

Future Technology Group • Mission is to investigate, understand and recommend technologies of importance to the NERSC center and its user base in the 3-5 year timeframe • Checkpoint/Restart to enable production computing for Linux • Target OS is Linux; User or system administrator initiated • Specifically aimed at parallel MPI jobs • Part of Scalable Systems Software SciDAC project • Infiniband Study • IB is the next “big thing” in system area networking • Switched fabric, O/S bypass, one-sided messaging, self healing • IPv6 addressing
Big Data and Remote Visualization: Visapult • Motivation: remote and interactive visualization of large scientific data over a wide area network. • Framework and application for remote direct volume visualization of large structured mesh data. • Visapult winner of SC2001 Bandwidth Challenge Source Volume
Scientific Computing Group • Computational materials science • electronic structure calculations, molecular dynamics • Environmental and earth sciences • climate modeling, groundwater flow simulation, modeling of the earth • Computational Physics • cosmic microwave background radiation, high-energy neutrino detection, accelerator modeling • Numerical linear algebra • eigen/singular value computations, sparse matrix computations • extended precision basic linear algebra subprograms • environments and tools
Advanced Computational Testing and Simulation (ACTS) • Make ACTS tools available on NERSC platforms • Enable large scale scientific applications • Extended support for experimental software • Perform independent evaluation of tools • Provide consistent application interfaces • Coordinate efforts with other supercomputing centers • Educate and train • Provide technical support (acts-support@nersc.gov) • Maintain ACTS information center (http://acts.nersc.gov)
Use of ACTS Tools Scattering in a quantum system of three charged particles (Rescigno, Baertschy, Isaacs and McCurdy, Dec. 24, 1999), SuperLU. Cosmic Microwave Background Analysis, BOOMERanG collaboration, MADCAP code (Apr. 27, 2000), ScaLAPACK.
Vision • Listening mode • Some observations (after 2 months) • Clear that NERSC is doing world class research • Leaders in the application of modeling and simulation to science • Good balance of applications, computer science, and algorithms that benefits the entire community • Challenges • Delivery on SciDAC goals • Earth Simulator response: advanced architecture research • Maintaining a balance that will successful track record
