Humanities and High Performance Computers Connect at NERSC
High performance computing and the humanities are finally connecting — with a little matchmaking help from the Department of Energy (DOE) and the National Endowment for the Humanities (NEH). Both organizations have teamed up to create the Humanities High Performance Computing Program, a one-of-a-kind initiative that gives humanities researchers access to some of the world’s most powerful supercomputers.

A Rising Tide of Cosmic Data
In 1998 the balloon-borne BOOMERANG and MAXIMA experiments made what were then the highest-resolution measurements of minute variations in the temperature of the cosmic microwave background radiation (CMB). Their high resolution was achieved by scanning small patches of the sky to gather unprecedented volumes of data. The analysis of these datasets presented a significant computational challenge – they were the first CMB datasets to require supercomputing resources. Read More »
IMPACTS: On the Threshold of Abrupt Climate Changes
Abrupt climate change is a potential menace that hasn’t received much attention. That’s about to change. Through its Climate Change Prediction Program, the U.S. Department of Energy’s Office of Biological and Environmental Research (OBER) recently launched IMPACTS – Investigation of the Magnitudes and Probabilities of Abrupt Climate Transitions – a program led by William Collins of Berkeley Lab’s Earth Sciences Division (ESD) that brings together six national laboratories to attack the problem of abrupt climate change, or ACC.

Visualizing the unseen forces of turbulence
Its invisible eddies and vortexes can dramatically alter the flight of everything from golf balls to hypersonic jets. Grasping the vast power of turbulence could help researchers design better weather forecasts, more efficient cars, quieter helicopters and even faster ships that “float” through the high seas on a cushion of air.

A Computer for the Clouds
A proposed supercomputer would do just one job--model global climate--but consume far less electricity than a general-purpose machine. Read More »
Code Booster: Award-winning research on code optimization explores multicore computing
At the 2008 IEEE International Parallel and Distributed Processing Symposium (IPDPS) held in Miami, the award for Best Paper in the “applications” category went to a research paper exploring ways to make a popular scientific analysis code run smoothly on different types of multicore computers.

A Supercomputer Takes Humanities Scholars Into the 21st Century
The phrase "one million" in grant announcements tends to be eye-catching because it is usually linked to the word "dollars." But late Monday afternoon, when officials at the National Endowment for the Humanities used that figure in describing a new grants program, they were not talking about money. "We are offering one million hours of high-performance computing," said Brett Bobley, director of the endowment's new Office of Digital Humanities.... Read More »
Ceramic, Heal Thyself
A new computer simulation has revealed a self-healing behavior in a common ceramic that may lead to development of radiation-resistant materials for nuclear power plants and waste storage. DOE's Office of Basic Energy Sciences funded the research, which was performed on massively parallel supercomputers in the William R. Wiley Environmental Molecular Sciences Laboratory (EMSL) at PNNL, and the National Energy Research Scientific Computer Center at Lawrence Berkeley National Laboratory. Read More »
