At 14, SuperLU Solver Library Still Growing in Popularity
Since its launch in 1999, the SuperLU software library for solving sparse linear systems of equations has become the third most downloaded software at Berkeley Lab. Between Oct. 1, 2011 and Sept. 30, 2012, SuperLU was downloaded 24,303 times, nearly a 50 percent increase over the 16,876 downloads the previous year. Read More »
Berkeley Code Captures Retreating Antarctic Ice
Satellite observations suggest that the shrinking West Antarctic ice sheet is contributing to global sea level rise. But until recently, scientists could not accurately model the physical processes driving retreat of the ice sheet. Now, a new ice sheet model—called Berkeley-ISICLES (BISICLES)—is shedding light on these details. Read More »
Taghrid Samak Works to Affect Social Development in Egypt

A Massive Stellar Burst, Before the Supernova
An automated supernova hunt is shedding new light on the death sequence of massive stars—specifically, the kind that self-destruct in Type IIn supernova explosions. Digging through the Palomar Transient Factory (PTF) data archive housed at the Department of Energy’s NERSC at Berkeley Lab, astronomers have found the first causal evidence that these massive stars shed huge amounts of material in a “penultimate outburst” before final detonation as supernovae.

CRD’s Daniel Burke Elevated to IEEE Senior Member
Daniel Burke, who joined the Computational Research Division last fall as a project manager for the new Computer Architecture Lab, has been elevated to the grade of Senior Member of the IEEE this year. Senior Member is the highest professional grade of the IEEE for which a member may apply and only about 8 percent of IEEE’s 416,000 members have achieved this level. Read More »
Berkeley Lab's CRD Contributes to Breakthroughs of the Year
Every year, Science magazine editors and staff sift through numerous scientific accomplishments and ultimately crown one “Breakthrough of the Year.” Of the top 10 finalists for 2012, Lawrence Berkeley National Laboratory (Berkeley Lab) computational researchers were major contributors to two accomplishments, including the winner: Discovery of the Higgs Boson.

Can We Accurately Model Fluid Flow in Shale?
Shale is a sedimentary rock consisting of layered, fine-grained clay minerals and, often, organic matter such as kerogen, the source of oil and gas. Now, CRD researchers have developed a new mathematical model that incorporates kerogen in calculating how gas and oil become available and how long a reservoir is liable to keep producing.

Computational Researchers Help Develop Next-Gen Batteries
As part of DOE's new Batteries and Energy Storage Hub, NERSC and CRD expertise will be leveraged to predict the properties of electrolytes. When JCESR is up and running, collaborators will be able to combine these results with the existing Materials Project database to get a complete scope of battery components. Read More »
