Lab Participates in NASA Earth Day Global Selfie

Wednesday, April 23rd, 2014

Employees from NERSC, ESNet, the Joint Genome Institute, Earth Sciences, the Molecular Foundry (pictured), and the Advanced Light Source gathered to take selfies as part of NASA’s worldwide celebration of Earth Day yesterday. NASA astronauts brought home the first ever images of the whole planet from space. Now NASA satellites capture new images of Earth every second. For Earth Day they tried to create an image of Earth from the ground up while also fostering a collection of portraits of the people of Earth. Check out our full #GlobalSelfie recap on Storify.

Lab Cybersecurity Experts Monitor ‘Heartbeat’ of Heartbleed Bug

Friday, April 18th, 2014

[New York Times] Ever since the Heartbleed bug was exposed last week, the question everyone has been asking is: Did anyone exploit it before a Google researcher first discovered it? Security researchers at Berkeley Lab’s Computational Research Division and NERSC say that it is still possible to look for past Heartbleed exploitations by measuring the size of any messages sent to the vulnerable part of the OpenSSL code, called the Heartbeat, and the size of the information request that hits a server.

To Bridge LEDs’ Green Gap, Scientists Think Small…Really Small

Tuesday, April 8th, 2014

Nanostructures half the breadth of a DNA strand could improve the efficiency of light emitting diodes (LEDs), especially in the “green gap,” a portion of the spectrum where LED efficiency plunges, simulations carried out at NERSC have shown. The semiconductor indium nitride (InN), which typically emits infrared light, will emit green light if reduced to 1 nanometer-wide wires, University of Michigan researchers calculated. What’s more, the color of light could be controlled by changing the width of nanowire, leading to natural-looking, white light that can be “tuned” to taste, for example sunlight, lamp light or even candle light.

Petascale Post-Doc Project a Supercomputing Success Story

Thursday, April 3rd, 2014

The first post-doctoral research project centered at the National Energy Research Scientific Computing Center (NERSC) is being credited with helping its participants advance their careers and boosting the state-of-the-art in high performance scientific computing software applications. The Computational Science and Engineering Petascale Initiative — aka the Petascale Post-doc Project — was unveiled in 2009. The goal was to hire several post-doctoral researchers to work with science teams on research in key application areas that support DOE’s energy mission and encourage the use of NERSC supercomputers for energy research. The program was funded through ARRA. More>

NERSC Tools Pave Way for Team Science

Monday, March 24th, 2014

For nearly a decade, computational scientists at the National Energy Scientific Research Computing Center (NERSC) have been working with researchers around the globe to develop online tools that are changing the way they compute and collaborate at NERSC. The result is a growing body of “science gateways,” web portals that scientists are using to discover new materials, better understand matter, and unlock the secrets of our universe. More>

Disordered Materials Hold Promise for Better Batteries

Wednesday, February 26th, 2014

Because lithium batteries are among the lightest and most energetic rechargeable batteries available, a lot of research is being done to facilitate their use in electronic devices. Using supercomputers at the National Energy Research Scientific Computing Center (NERSC) and other facilities, researchers at the Massachusetts Institute of Technology, and Brookhaven National Laboratory, have found a new avenue for such research: the use of disordered materials, which had generally been considered unsuitable for batteries.

Throwback Thursday…the Birth of NERSC

Thursday, February 20th, 2014

The Controlled Thermonuclear Research Computer Center — now known as NERSC — was established in 1974 and unveiled its first supercomputer that same year: a Control Data Corporation 6600 “borrowed” from the weapons program at Lawrence Livermore National Laboratory. When introduced in 1964, the CDC 6600 was considered the fastest computer in the world, computing about 1 million calculations per second. Compare that to the iPad-2, which performs about 1.65 billion calculations per second. Go here for more on the history of NERSC, which celebrates its 40th anniversary this year.

Decoding the Molecular Mysteries of Photosynthesis

Wednesday, February 19th, 2014

Scientists from the UC Berkeley and Berkeley Lab are using simulations performed at NERSC to understand the role certain proteins play in the production of energy via photosynthesis. Their aim is to understand how plants regulate and heal their photosynthetic systems. The work could lead to more robust and efficient solar energy capture using artificial photosynthesis. More>

When a supercomputing center installs a new system, users are invited to make heavy use of the computer as part of the rigorous testing. In this video, find out what top scientists have discovered using Edison, a Cray XC30 supercomputer, and how NERSC’s newest supercomputer will accelerate their future research. More>

NERSC Announces Second Annual HPC Achievement Awards

Thursday, February 6th, 2014

The National Energy Research Scientific Computing Center (NERSC) announced the winners of its second annual High Performance Computing (HPC) Achievement Awards during its annual User Group meeting. The awards recognize NERSC users who have either demonstrated an innovative use of HPC resources to solve a scientific problem, or whose work has had an exceptional impact on scientific understanding or society. To encourage younger scientists who are using HPC in their research, NERSC also presented two early career awards. More>
