The United States is launching a push to regain the lead in the competition over who has the most powerful computer, announcing plans Wednesday to build the world's fastest civilian computer at Oak Ridge National Laboratory in Tennessee with the help of three private computer companies. The team envisions a computer capable of performing 50 trillion calculations per second on a sustained basis. The record is 36 trillion calculations per second, held by a Japanese machine.

A new Japanese supercomputer has taken the title of world's fastest away from an American computer, zipping along nearly five times faster than its closest competitor. The NEC Earth Simulator tops the 2002 list of fastest supercomputers released by a research group led by Jack Dongarra, a University of Tennessee computer science professor. The NEC Earth Simulator works at a speed of 35,600 gigaflops. A gigaflop equals 1 billion mathematical operations per second.

In a move that pits national security concerns against commercial interests, President Bush on Wednesday eased restrictions on the export of supercomputers to Russia, China, Pakistan and other nations. Bush notified congressional leaders that his administration will more than double the amount of computing power allowed to be exported to "tier 3" nations, a group of more than three dozen countries that pose nuclear proliferation concerns, including Israel and India.

NEC Corp. has agreed to settle a long-standing dispute with U.S. rival Cray Inc. that could open the door for the Japanese company to sell its supercomputers in the United States for the first time in four years. The Tokyo-based electronics maker will invest $25 million in Cray, which also makes supercomputers, and will drop a complaint against duties imposed on NEC supercomputer sales in the U.S. in 1997. Cray will distribute NEC supercomputers in North America and ask the U.S.

Genome hunters at the U.S. Energy Department and Celera Corp. announced a marriage of computer technology and biology Friday, saying they will mine the human gene map for information they hope will transform medicine. They will team up, along with Compaq Computer Corp., to write powerful computer programs and to build a giant new computer to go through the genome sequence and find out where the genes are and what they do.

In a feat akin to catching lightning in a bottle, researchers have been able to reduce the speed of light from 186,000 miles per second to zero, trapping light beams for short periods of time before allowing them to burst forth again at full speed. The achievement does not break any laws of physics, but it does illustrate the mysterious, bewildering world of quantum physics, where things are not always what they seem and where physicists often do the seemingly impossible.

Computer Sciences Corp. said it would open pay-per-use access to its banks of super-fast supercomputers over the Internet. CSC said the new service would allow supercomputing power on demand to companies that can't afford their own expensive high-performance machines, which typically operate at speeds about 10,000 times faster than a desktop computer. The El Segundo-based firm said the new service would offer access through a Web portal to its existing High Performance Computing. Called e-HPC.

IBM Corp. said it's providing a new class of low-cost supercomputer that uses the Linux alternative operating system, allowing researchers and developers access to computational power they previously could not afford. The National Computational Science Alliance, made up of 50 academic, government and research partners, said it would use the system of IBM computers as a part of its effort to create a new, highly sophisticated computer network for research.

IBM Corp. said it will spend $100 million to develop a supercomputer that's 500 times faster than current models. The "Blue Gene" computer will process more than 1,000 trillion calculations per second, 2 million times faster than a personal computer. That's 1,000 times more powerful than "Deep Blue," which beat chess champion Garry Kasparov in 1997. The machine is designed to help scientists understand genes and come up with cures for diseases.

IBM Corp. said it has the most supercomputers in the world's biggest research sites, surpassing Silicon Graphics Inc. for the first time. IBM has 141 of the powerful machines at the top 500 computer sites, according to the Top500 list that's published twice a year. IBM's presence at the government, research and university facilities is a 36% increase from 104 systems in 1998.
