Supercomputer builds a virus

March 14, 2006

One of the world’s most powerful supercomputers has built a computer model of the satellite tobacco mosaic virus.

The researchers say the simulation is the first to capture a whole biological organism in such intricate molecular detail.

Running on a machine at the National Center for Supercomputing Applications, Urbana, the program calculated how each of the million or so atoms in the virus and a surrounding drop of… read more

Supercomputer climate model whips up a storm

October 1, 2003

Virtual hurricanes have appeared in computer models of the Earth’s climate for the first time.

The Earth Simulator in Yokohama, Japan, the world’s fastest supercomputer, can run models with cells as small as 10 kilometers, allowing for study of detailed features of the weather, such as tropical storms.

Supercomputer improves diagnosis of osteoporosis

July 3, 2008

Researchers at IBM Zurich Research Laboratory and ETH Zurich are using a Blue Gene supercomputer to simulate human bone structure and predict where bones are likely to fracture.

The research could help bring clinical tools to improve the diagnosis and treatment of osteoporosis, a widespread disease that worldwide affects one in three women and one in five men over the age of 50.

When running simulations for a… read more

Supercomputer is made from off-the-shelf PlayStation 3 gaming consoles

March 25, 2011

Computer scientists at the Air Force Research Lab in Rome, NY, have assembled one of the world’s largest, fastest, and cheapest supercomputers by linking together 1,716 PlayStation 3s, says Mark Barnell, director of high-performance computing at the Air Force Research Lab.

The supercomputer can scan or process text in any language at 20 pages per second, fill in missing sections it has never seen with 99.9 percent accuracy, and… read more

Supercomputer Needs Super-Big Space

September 6, 2001

Los Alamos National Labs’ new “Q” 30 teramips supercomputer requires a 300,000-square-foot building and 7 megawatts of electricity for cooling — ten percent of all the electricity piped into Los Alamos Labs and surrounding community.While today’s fastest machine can perform 10 trillion calculations a second, visionaries are thinking about machines 100 times faster.

That is probably eight or nine years away, Mike Vildibill, deputy director at San Diego Supercomputer… read more

Supercomputer on a chip

March 13, 2001

Sony Computer Entertainment, Toshiba and IBM announced today they are teaming up on a $400 million project to develop a “supercomputer-on-a-chip.”

Code-named “Cell,” the new microchips will employ the world’s most advanced chip-making techniques, including copper wires, silicon-on-insulator transistors and low-K dielectric insulation, with features smaller than 0.10 microns.

The result will be consumer devices that are more powerful than IBM’s Deep Blue supercomputer, operate at low power,… read more

Supercomputer Simulations Reveal Strongest Carbon Nanotubes

September 20, 2001

A team of researchers has used computer simulations to discover carbon fibers with mechanical strength comparable to that of diamond. In a paper published in Physical Review Letters, Crespi, graduate student Dragan Stojkovic, and recent Ph.D. graduate Peihong Zhang report that they discovered incredibly strong and stiff carbon tubes about 0.4 nanometers in diameter.

Using supercomputers at the San Diego Supercomputer Center (SDSC), the University of Michigan, and the… read more

Supercomputer smashes world speed record

April 18, 2002

A Japanese supercomputer has recorded the world’s fastest floating point calculation speed at 35.61 teraflops — five times faster than IBM’s ASCI White’s 7.23 teraflops.
The supercomputer is installed in The Earth Simulator at the Marine Science and Technology Center in Kanagawa. It which simulates climate change using data collected by Earth-monitoring satellites.

According to an NEC spokesman, the supercomputer was tested using the Linpack benchmarking software.… read more

Supercomputer sweepstakes heat up with new NEC entry

October 21, 2004

NEC has begun marketing the SX-8 vector supercomputer. It features peak processing performance of 65 teraflops, which according to NEC tops rival IBM Corp.’s latest entry, Blue Gene/L.

Supercomputer to Use Optical Fibers

November 18, 2002

The California Institute for Telecommunications and Information Technology plans to announce on Monday a campus-wide supercomputer woven together with optical fibers at the University of California at San Diego.

An example of a new trend in advanced computing known as grid computing, the “optiputer” will initially consist of about 500 processors linked via an optical switching system that will permit parts of the computer to share information at the… read more

Supercomputer Visuals Without Graphics Chips

August 10, 2009

Rather than moving massive datasets to a specialized graphics-processing cluster for rendering, researchers are writing software that allows the thousands of processors in a supercomputer to do the visualization themselves.

Supercomputer-based neural net to mimic the brain planned

September 16, 2003

Plans to build the “world’s biggest spiking neural network” to mimic the brain were announced by Mountain View, Calif.-based Artificial Development at the Accelerating Change Conference on Sunday.

The CCortex system will be a “massive spiking neuron network emulation and will mimic the human cortex, with 20 billion layered neurons and 2 trillion 8-bit connections,” according to AD’s President and CEO Marcos Guillen, listed in the… read more

Supercomputer-discovered drug could lead to new blood pressure medicines

May 5, 2008

University of Florida researchers used a supercomputer to compare the shapes of 140,000 molecules with the structure of the ACE2 enzyme, which protects against high blood pressure.

They found a drug that lowers blood pressure, improves heart function, and prevents damage to the heart.

Supercomputer-level millisecond-scale sampling for protein simulation on a desktop computer

August 8, 2012

Images showing the conformational space explored by the protein in the 1ms conventional MD Anton simulation, and the 500ns aMD simulation. The red diamond marks the crystal structure where both simulations were started from; the triangles represent important structures found in the 1ms simulation. The lower image shows that with a single graphics card running 500ns of accelerated MD, the same structures can be sampled and the same relative conformational space can be explored. Principal Component Analysis (PCA) captures the slowest motions of the protein, which correspond to conformational changes on long timescales. Moving L to R along the x-axis captures the primary slow rocking motion of the protein; moving vertically on the y-axis captures the second slowest motion, or wagging movement.<br />

Computer scientists and biochemists at the University of California, San Diego, have developed advanced GPU accelerated software and demonstrated for the first time that they could sample biological events that occur on the millisecond timescale using only an upgraded desktop computer equipped with a relatively inexpensive graphics processing card.

These results have the potential to bring millisecond-scale sampling, now available only on a multi-million dollar supercomputer,… read more
