Getting the big picture
Dozens to hundreds of interconnected personal computers (PCs), stacked up row after row and operating simultaneously: that in a nutshell describes many of the latest high-performance supercomputers.

Echoes of the past in silicon chips
Thermal oxide is the real on-off switch for your computer. The nanometers-thick film on the surface of silicon transistors helps turn on and off the flow of electricity through the transistor, providing the 0 and 1 binary signals modern electronics run on. There are several million transistors on each computer chip.

Uncovering secrets of living cells
Probing microbes to determine what they are made of and what drives them requires more than mass spectrometers, microarrays, and microscopes. Computational models run on supercomputers have been key contributors to our growing understanding of these single-cell organisms.

Exploring and modeling 21st Century materials
The 1986 discovery of high-temperature superconductivity sparked the quest for room-temperature superconductors that could transmit electrical current without heat losses and without the need for an expensive coolant such as liquid helium. Room-temperature superconductors could make possible ultra-efficient power transmission lines, practical electric cars, and superconducting magnets that could bring high-speed levitated trains and smaller, more efficient, and less costly rotating machinery, appliances, particle accelerators, electric generators, and medical imaging devices.

Strategic supercomputing comes of age
With the birth of the Stockpile Stewardship Program (SSP), the need for better computer simulations became paramount to help ensure that the nation's nuclear weapons stockpile remained safe, reliable, and capable of meeting performance requirements.

DZero breaks new ground in global computing efforts
Searching for subatomic particles very much resembles the often-cited search for the needle in the haystack. Since the beginning of Collider Run II in March 2001, DZero scientists have collected more than 550 million particle collisions. The data fill five stacks of CDs as high as the Eiffel tower--storage cases not included. And the (hay)stacks are growing every day.

Critical information for critical situations
Each year, tens of thousands of people around the world die in natural and human-caused disasters. In an emergency, the ability to obtain and track highly dynamic status information is crucial for control rooms, incident command centers (ICCs) and emergency operations centers (EOCs).

Parallel computers 'evolutionize' research
A major research trend is harnessing advanced computers to complement theory and experiment. Advanced computing allows scientists to conduct experiments that could not otherwise be done, to test possible experiments before investing the time and money to physically carry them out, and to create models of complex phenomena.

Globus Toolkit enables Grid computing
Argonne technology is bringing closer the day when the Internet can let people share computing, storage, data, programs and other resources as easily as the electric power grid allows people and energy companies to share electricity.

Fastest unclassified supercomputer in the west
The U.S. Department of Energy's Pacific Northwest National Laboratory currently has the fastest operational unclassified supercomputer in the U.S. The 11.8-teraflops system at the William R. Wiley Environmental Molecular Sciences Laboratory will advance novel studies in research areas such as atmospheric chemistry, systems biology, catalysis, and materials science.

The next-generation supercomputer
In September 2003, the U.S. Department of Energy's Oak Ridge National Laboratory and Cray, Inc., of Seattle, Washington, will deploy Cray's X1 system at ORNL's Center for Computational Science. This next-generation supercomputer will be instrumental in addressing problems related to climate, biology, nanoscale materials, fusion, and astrophysics.

Mozart—A genius at assessing your Web site
Scientists at Pacific Northwest National Laboratory have developed an Internet assessment tool, called Mozart, that quickly archives and analyzes entire Web sites based on search terms provided by the user and built-in search libraries containing hundreds of key phrases designed to find sensitive information.

Scientific discovery through advanced computing
Fifty-one projects will receive a total of $57 million this fiscal year to develop the scientific computing software and hardware infrastructure needed to use terascale computers to advance fundamental research in several areas related to the department's missions, including climate modeling, fusion energy sciences, chemical sciences, nuclear astrophysics, high energy physics and high performance computing.

Algorithms -- A new perspective on data
We live in the age of information. Analysts are among those inundated with data. But with the aid of powerful computing techniques, analysts can make sense of volumes of data that come in many forms--text, numbers, images, video, audio.

Designer molecules set the trend for advancing science
Researchers at the U.S. Department of Energy's Pacific Northwest National Laboratory are developing computational tools to rapidly design and build new molecular structures and screen them before synthesizing the real molecule. The power of this approach is illustrated in the April 26, 2002 issue of the Journal of the American Chemical Society.

Ames Laboratory puts the 'squeeze' on communications technology
A new message-passing library that makes it possible to extract optimum performance from both workstation and personal computer clusters, as well as from large massively parallel supercomputers has been developed by researchers at Ames Laboratory. The new library, called MP_Lite, supports and enhances the basic capabilities that most software programs require to communicate between computers.

Biosig finds new meaning in microscope images
A team of computer scientists working with cell biologists at Lawrence Berkeley National Laboratory has created BioSig, a web-based bioinformatic system that links collections of microscope images to a wide variety of quantitative experimental data. The new program can be used by multiple researchers to answer questions and test hypotheses about protein expression, cell morphology, and cellular organization in tissues and cell cultures.

Mapping the microbial world
Scientists are cataloguing and mapping the life inside Yellowstone’s hot pools. Hardy microorganisms ranging from emerald-green bacteria to fire-red rock slime have long fascinated microbiologists with their ability to live in the scalding hot water at Yellowstone National Park, the acidic ore deposits of abandoned mines or the salt pools of the Great Salt Lake.
