Performance Evaluation Activites at NERSC
Adrian Wong, Advanced Systems Group
An overview of the performance evaluation activities is presented. These activities cover individual application benchmarks, system software testing, profiling and instrumentation and tracking technology.
Seaborg Code Scalability Project
Richard Gerber, User Services Group
Green's function Monte Carlo Calculations of Light Nuclei
Steven Pieper, ANL
Reliable calculations of nuclei using realistic interactions are particularly difficult due to the strong spin and isospin dependence of the forces. Both two- and three-nucleon forces must be included to reproduce the total binding energy. In the last few years significant progress has been made in Green's function Monte Carlo (GFMC) calculations of up to 10-body nuclei. These calculations are quite large; each ten-nucleon calculation requires more than 10,000 processor-hours on modern parallel computers. I will briefly describe these calculations with an emphasis on the computational needs.
Lattice QCD in Extreme Environments
Don Sinclair, ANL
QCD describes hadrons (strongly interacting particles: proton, neutron, pion, etc.) as being bound states of quarks held together by gluons, and also describes their strong interactions. Lattice QCD replaces continuum space-time by a discrete 4-dimensional lattice. This allows direct simulations of QCD dynamics and thus the calculation of those aspects of hadronic physics which are inaccessible to perturbative expansions in the QCD coupling constant. We are using such simulations to study the phase transition from hadronic matter to a quark-gluon plasma at high temperatures. In addition we are studying QCD at finite isospin density at zero and finite temperature, as part of a project to study the phases of nuclear matter.
A brief review of climate change simulations will be given. NCAR has developed several coupled atmosphere, ocean, sea ice, and land/surface models in close collaboration with DOE laboratories and university scientists. These state of art models have been used to study past, present, and future climate change. Several examples will be discussed as well as a glimpse into the future.
The talk provides an informal progress report on the SciDAC Plasma Microturbulence Project sponsored by OFES and OSCR. This project addresses the direct numerical simulation of plasma microturbulence due to drift-waves that controls the confinement of energy in tokamak fusion experiments.
Reconnection is a ubiquitous process in magnetized plasmas, occuring everywhere from tokamaks to solar flares to accretion discs. I will briefly discuss the scientific problem, the code we use in our simulations, and some recent results (obtained from simulations done at NERSC) on the effects of turbulence and wave-particle interactions on reconnection.
Report from DOE - SciDAC Update, Allocations Update, Applications Matrix
Buff Miner, U. S. Department of Energy
The NUG Executive Board Elections Process
Ricky Kendall, Ames Laboratory, University of Iowa
Blue Planet Proposal
Bill Kramer, NERSC
Adjustments to NERSC's 5-Year Plan
Bill Kramer, NERSC
ERCAP Allocation Requests for FY 2004
Francesca Verdier, User Services Group
New Seaborg Queue Configuration Results
David Turner, User Services Group
Results of Seaborg's new batch configuration will be presented, with an emphasis on large-scale parallel jobs and system throughput.
Evaluation of Checkpoint/Restart on the SP
Jay Srinivasan, Computational Systems Group
We present some results of an evaluation of the checkpoint/restart capability of LoadLeveller on the IBM SP, as well as some information on its possible use.
Visualization Plans
Wes Bethel, Visualization Group
Grid and Portal Plans
Steve Chan, Network and Security Group
Grid technology is making the transition from research topic into a production tool. In this presentation, we give an overview of work at NERSC to provide Grid tools for users who need, or will need the Grid for their computational work. The presentation will not try to cover the general topic of Grids, but will focus on NERSC production Grid efforts.
GUPFS Project Progress Report
Greg Butler, NERSC Advanced Systems Group
The Global Unified Parallel File System project is actively engaged in finding and evaluating shared file system, Storage Area Network fabric, and storage device technologies. A methodology for conducting evaluations, including parallel I/O benchmarks, was developed and is being used to test multiple file systems, fabrics, and storage devices. This talk presents a project update, including a summary of recent activities, some of the evaluation results, and near term plans.
An Access Grid virtual meeting is an internet-mediated audio-video conference. Access Grid facilities are available at most DOE sites; see your local ESNet representative to find out the location and availability of an Access Grid Node at your site.
