National Energy Research Scientific Computing Center Announces Acceptance of One of the World's Largest Supercomputers

November 1, 2007

The U.S. Department of Energy’s (DOE) Lawrence Berkeley National Laboratory and Cray Inc. today announced the successful completion of the acceptance test of one of the world’s largest supercomputers. Installed at the DOE’s National Energy Research Scientific Computing Center (NERSC), the powerful Cray XT4™ system contains nearly 20,000 processor cores and has a top processing speed of more than 100 teraflops.

Model Comparisons

November 1, 2007

Scientists from the Advanced Plasma Microturbulence Project have published several papers recently that show how they resolve the significant differences between two types of electron temperature gradient (ETG) turbulence simulations in fusion research. The researchers have been running simulations at NERSC using particle-in-cell (PIC) and continuum gyrokinetic codes in order to reconcile the large gap of electron thermal conductivity values between the two types of simulations.Investigating… Read More »

Up to Speed

May 1, 2007

A DOE workshop hosted by NERSC  brought together the international supercomputing community in May to identify  challenges for deploying petascale systems,  a collaboration that resulted in a series of  recommendations.  The two-day meeting in San Francisco  attracted about 70 participants from roughly  30 supercomputer centers, vendors, other  research institutions and DOE program  managers from Advanced Scientific  Computing Research (ASCR), which funded  the workshop. The… Read More »

Wanted: Killer Apps

May 1, 2007

NERSC staff members are playing an  increasingly active role in high-performance computing software integration and  development, as they face a greater  demand for marrying software from a  variety of supercomputer makers with  applications from a wide range of scientific fields.  That’s the message from David  Skinner, head of NERSC’s Open  Software and Programming Group, which  carries out in-house software development and deployment projects to help  researchers run their… Read More »

Open for Science

May 1, 2007

More NERSC users can now launch  and manage their work at multiple computing sites by going through a centralized  grid, thanks to efforts to connect NERSC’s  systems to the Open Science Grid (OSG).  The SGI Altix 350 visualization server,  named DaVinci, joined the OSG last  month, the latest in a long-range plan to  connect all NERSC supercomputers to the  grid, said Shreyas Cholia, a member of  the Open Software and Programming  Group at NERSC.   Making NERSC part of the more… Read More »
