Invisible Milky Way Satellite Uncovered With Help from NERSC

March 23, 2011

Astronomers predict that large spiral galaxies like our Milky Way have hundreds of satellite galaxies orbiting around them. Using supercomputers at NERSC, scientists developed a mathematical method to uncover these “dark” galaxies. When she applied it to our own Milky Way, she discovered a faint satellite might be lurking on the opposite side of the galaxy from Earth.


A Superbright Supernova That’s the First of Its Kind

December 2, 2009

A superbright supernova found in a dwarf galaxy by the Nearby Supernova Factory based at Berkeley Lab is the first confirmed example of a pair-instability supernova, the result of the partial core collapse and thermonuclear detonation of an enormously massive star, like the earliest stars in the Universe.


NERSC Helps Expose Cosmic Transients

June 15, 2009

Finding rare and fleeting cosmic events not only requires the right kind of telescope and camera, it depends on high-performance computing that can pinpoint objects of interest among thousands of sky images while there’s still time for follow-up observations. Caltech and DOE’s NERSC join forces in just such a search, the Palomar Transient Factory.


Planck Mission Has Roots and Branches in Berkeley

May 14, 2009

Berkeley Lab’s interest in the Planck mission to map the cosmic microwave background goes back to a proposal that evolved into the present design – and extends into the future as NERSC’s powerful computers stand by to analyze the coming flood of data.


A Research Center for Understanding How to Store CO2 Underground

April 28, 2009

The Department of Energy will invest $777 million in 46 new Energy Frontier Research Centers over the next five years as part of President Barack Obama’s plans to reinvigorate American science. Berkeley Lab will be home to the Center for Nanoscale Control of Geologic CO2, led by Don DePaolo, director of the Earth Sciences Division, to study carbon dioxide storage deep underground.


A Rising Tide of Cosmic Data

December 10, 2008

From COBE to Planck and beyond, the volume of data from measurements of the cosmic microwave background continues to grow by orders of magnitude. The Computational Cosmology Center, a collaboration between Berkeley Lab’s Physics Division and Computational Research Division, has algorithms and implementations in the works so NERSC’s supercomputers can handle the rising tide.


IMPACTS: On the Threshold of Abrupt Climate Changes

September 17, 2008

Abrupt climate change is the focus of IMPACTS, a major new program bringing together six DOE national laboratories to investigate the instability of marine ice sheets, warming of the boreal forests and Arctic, megadroughts in the Southwest, and catastrophic release of methane from hydrates.


Multicore: Fallout From a Computing Evolution

August 15, 2008

Parallel computing used to be reserved for big science projects, but in two years that’s all changed. Even laptops and hand-helds use parallel processors. Unfortunately, the software hasn’t kept pace. Kahty Yelick, Director of NERSC, describes the resulting chaos and the computing community’s efforts to develop exciting applications that take advantage of hundreds of processors on a single chip.

Code Booster

June 20, 2008

The rush toward multicore processors in supercomputing and even in consumer electronics comes at the expense of the best available software. Samuel Williams and his colleagues in the Computational Research Division and NERSC used a powerful code that models magnetohydrodynamic turbulence to check out five multicores and found just one, the Cell Blade, that outperformed them all.


DOE Allocates NERSC Supercomputing Resources to Research

January 18, 2008

Contact: Jon Bashor, 510-486-5849

BERKELEY, Calif. — The U.S. Department of Energy announced today that it is allocating about 10.4 million CPU hours on supercomputers at the National Energy Research Scientific Computing Center (NERSC) at Lawrence Berkeley National Laboratory as part of a program to accelerate scientific discoveries in multiple disciplines, including climate, [...]
