Horst Simon Steps Down As NERSC Director

December 12, 2006

Horst Simon, who has been director of DOE's National Energy Research Scientific Computing Center (NERSC) since early 1996, announced last month that he was stepping down in order to focus his energy on the two other positions he holds at Lawrence Berkeley National Laboratory. Once a new director for NERSC is hired, Simon will concentrate on his duties as Associate Laboratory Director for Computing Sciences and Computational Research Division (CRD) Director. With the search for a new NERSC leader officially under way, Simon took some time to talk about his decision and how he sees his future. Read More »

INCITE Allocation Helping Drive Research in Future Accelerator Design

September 1, 2006

Using an allocation of 2.5 million processor hours on Seaborg at NERSC, a  team led by Cameron Geddes of  Lawrence Berkeley National Laboratory  is creating detailed 3D simulations of  laser-driven wakefield particle accelerators (LWFAs), providing crucial under- standing of the next generation of particle  accelerators and ultrafast applications in  chemistry and biology.  The allocation was awarded under DOE’s  Innovative and Novel Computational  Impact on Theory and Experiment … Read More »


First Cabinet of NERSC’s New Cray Supercomputer Arrives for Testing

September 1, 2006

Within weeks of the announcement that NERSC’s next large system will be a follow-on to the Cray XT3 supercomputer, the first cabinet of the new machine has been installed for testing at Berkeley Lab’s Oakland Scientific Facility. The new supercomputer, which will be among the world’s fastest general purpose system, will have a guaranteed sustained performance of at least 16 trillion calculations per second (with a theoretical peak speed of 100 trillion calculations per second) when… Read More »

NERSC Users Report Over 1,400 Publications in 2005

February 1, 2006

As part of their 2006 allocations request, NERSC users were asked to submit lists of articles and conference papers resulting from their computations at NERSC over the preceding 12 months. A total of 1,448 publications, which had either been published or accepted, were noted. The total does not include those papers listed as “submitted” or “in preparation.” “This is an inspiring list of publications, both in the number and the breadth of science covered,” said NERSC Division… Read More »

201 Users Participate in Annual User Survey

February 1, 2006

The results from the 2005 user survey are now available and show generally high satisfaction with NERSC’s systems and support.Areas with the highest user satisfaction include account support services, the reliability and uptime of the HPSS mass storage system, and HPC consulting.

NERSC Global Filesystem Now Provides Seamless Data Access from All Systems

February 1, 2006

In February, NERSC deployed the NERSC Global Filesystem (NGF) into production, providing seamless data access from all of the Centers’ computational and analysis resources. With NGF, users can now run applications on Seaborg, for example, then use  DaVinci to visualize the data without having to explicitly move a single data file. Greg Butler NGF is intended to facilitate sharing of data between users and/or machines. For example, if a project has multiple users who must all access a… Read More »

NERSC Team Takes StorCloud Honors at SC05 Conference

February 1, 2006

One of the goals of providing comprehensive computing resources is to make the different components “transparent” to the end user. But if you are staff members demonstrating a groundbreaking approach for accessing distributed storage, such invisibility isn’t so desirable. That was the case for a NERSC/LBNL team competing in the StorCloud Challenge at the SC05 conference held Nov. 12-18, 2005, in Seattle.The team, led by Will Baird of NERSC’s Computational Systems Group, was given an… Read More »
