Supercomputing goes global

January 11, 2005

The world’s most powerful supercomputer likely will evolve into a grid architecture of loosely coupled systems harnessed logically to a single task across a global network.

A grid holds the most promise for delivering the biggest and baddest theoretical supercomputing architecture imaginable, a virtual multiple-instruction/multiple-data, or MIMD, global supercomputer.

Grid architectures rely more on specialized software than on fast hardware, and they’re attracting lots of research. Users in… read more

Supercomputing on a cell phone

September 2, 2010

(David Knezevic and Dinh Bao Phuong Huynh)

Researchers in MIT’s Department of Mechanical Engineering have developed software that can simulate complicated physical phenomena — how cracks form in building materials, for instance, or fluids flow through irregular channels — on an ordinary smartphone.

Although the current version of the software is for demonstration purposes, the work could lead to applications that let engineers perform complicated calculations in the field, and even to better control systems for… read more

Supercomputing On Demand

San Diego Supercomputer Center (SDSC) has introduced OnDemand, a new supercomputing resource that will support on-demand users for urgent science applications.

Urgent applications that will make use of OnDemand range from making movies of Southern California earthquakes to systems that will help give near real-time warnings based on predictions of the path of tornados or a hurricane, or foretell the most likely direction of a toxic plume… read more

Supercomputing platform built for gaming

May 13, 2002

The “Butterfly Grid,” a distributed supercomputer games network, could allow more than a million people to play graphics-rich games together via the internet.
The project borrows scientific supercomputer “grid” techniques developed to seamlessly connect scientific computers for research, sharing power and storage via the Internet.

West Virginia-based Butterfly has developed the software that will allow game developers to enable any game to plug into the network… read more

Supercomputing Resurrected

February 11, 2003

Last year, Japan fired up an ultrafast computer that puts its closest competitors to shame. What will it take for the United States to catch up?

Supercomputing: Suddenly Sexy

July 9, 2002

Supercomputing is beating Moore’s Law, with power for the same price doubling every 15 months.

NEC’s new Earth Simulator, rated at 35 teraflops is the world’s fastest and will ultimately act as Japan’s early warning of typhoons. But IBM’s 200 teraflops Blue Gene/L will soon top the list.

The next challenge for the supercomputing community is a petaflops machine, capable of a quadrillion floating-point operations per… read more

Supercomputing’s New Idea Is Old One

August 4, 2003

Scientists in government, industry and academia involved in the race to build the world’s fastest computing machines are now turning their attention once again to Seymour Cray’s elegant approach to building ultra-fast computers. The designs use special hardware that to handle the long strings of numbers in complex scientific computing problems.

Cray’s revival was helped by funding from the Pentagon’s Defense Advanced Research Projects Agency to develop prototypes of… read more

Superconducting Chips To Become Reality

May 29, 2009

Superconducting germanium doped by gallium has been produced by scientists at the Forschungszentrum Dresden-Rossendorf (FZD) research center.

Germanium as a new material for chips would enable both faster processes and further miniaturization in micro- and nanoelectronics.

levitation

A dramatic demonstration by physicist Boaz Almog from Tel Aviv University earlier this week illustrates how a superconducting plate can levitate above a track of permanent magnets, New Scientist TV reports.

Superconducting junctions eyed for quantum computing

November 24, 2002

Josephson junctions, a superconducting type of transistor, are being investigated as a possible route to scalable quantum computers by a physicist at the University of Michigan.

Superconducting memory flip-flops in an instant

April 21, 2006

An exotic form of electronic memory made using superconductors could someday be used to make computers that work at unprecedented speeds, say researchers.

Superconducting nanotubes

October 4, 2002

Researchers have discovered a way to convert nanotubes into superconductors by placing hydrogen on the exterior, leading to dense concentrations of charge-carrying electrons.

Carbon nanotubes are considered to be building blocks of future electronic and mechanical devices.

Superconducting nanowire devices could run and run

July 18, 2005

Researchers at Delft University of Technology and Philips Research Laboratories have combined semiconductor nanowires with superconducting contacts to make superconducting transistors. At temperatures below 1 K, the contacts induced superconductivity in the nanowires through the proximity effect.

Superconducting quantum integrated circuit may lead to future quantum computational architecture
