Science at Scale: SciDAC Astrophysics Code Scales to Over 200K Processors

June 18, 2010

Performing high-resolution, high-fidelity, three-dimensional simulations of Type Ia supernovae, the largest thermonuclear explosions in the universe, requires not only algorithms that accurately represent the correct physics, but also codes that effectively harness the resources of the next generation of the most powerful supercomputers.

Berkeley Lab Team Receives NASA Public Service Group Achievement Award

June 11, 2010

Three scientists from the Lawrence Berkeley National Laboratory’s (Berkeley Lab) Computational Cosmology Center (C3) are being honored with a NASA Public Service Group Award for developing the supercomputing infrastructure for the U.S. Planck Team’s data and analysis operations at the Department of Energy's National Energy Research Scientific Computing Center (NERSC).

How a Summer Internship—or a Weekend Lecture—Can Change a Life

June 9, 2010

Emily Chen still vividly remembers the lecture on gecko feet. She was an eighth grader attending Berkeley Lab’s Nano*High program to hear materials scientist Arun Majumdar explain how what he was learning about gecko feet might translate into a new adhesive product based on carbon nanotubes.

Computers Give Insights into Generating Power Like the Sun

June 7, 2010

If humans could harness nuclear fusion, the process that powers stars like our Sun, the world could have an inexhaustible energy source. In theory, scientists could produce a steady stream of fusion energy on Earth by heating up two types of hydrogen atoms—deuterium and tritium—to more than 100 million degrees centigrade until they become a gaseous stew of electrically charged particles, called plasma. Then use powerful magnets to compress these particles until they fuse together, releasing energy in the process. Read More »

Grace Hopper Powers Science on NERSC's New Cray XE6

June 4, 2010

American computer scientist Grace Hopper will power science on the cabinets of the National Energy Research Scientific Computing Center's (NERSC) petascale Cray XE6 system. A pioneer in the field of software development and programming languages, Hopper created the first compiler. She was a champion for increasing the usability of computers, understanding that their power and reach would be limited unless they were made to be more user-friendly. NERSC's new flagship machine is named "Hopper" in her honor. Read More »

Data Acquisition and Coordination Key to Human Microbiome Project

June 4, 2010

At birth, your body was 100-percent human in terms of cells. At death, about 10 percent of the cells in your body will be human and the remaining 90 percent will be microorganisms. That makes you a “supraorganism,” and it is the interactions between your human and microbial cells that go a long way towards determining your health and physical well-being, especially your resistance to infectious diseases.

Simulations Reveal That Earth's Silica Is Predominantly Superficial

May 24, 2010

Silica is one of the most common minerals on Earth. Not only does it make up two-thirds of our planet's crust, it is also used to create a variety of materials from glass to ceramics, computer chips and fiber optic cables. Yet new quantum mechanics results generated by a team of physicists from Ohio State University (OSU) show that this mineral only populates our planet superficially—in other words, silica is relatively uncommon deep within the Earth.

Berkeley Lab Scientists Build Software Framework for ATLAS Collaboration

May 17, 2010

Three thousand researchers in 37 countries are searching for the origins of mass, new dimensions of space and undiscovered forces of physics in the head-on collisions of high-energy protons at the Large Hadron Collider's ATLAS experiment. When ATLAS is turned-on, its detectors record about 400 collision events per second from a variety of perspectives, a rate equivalent to filling 27 compact disks per minute. Read More »

Bringing Clouds into Focus:

May 11, 2010

Clouds exert two competing effects on the Earth's temperature: they cool the planet by reflecting solar radiation back to space, but they also warm the planet by trapping heat near the surface. These two effects coexist in a delicate balance. Read More »
