Supercomputing

June 27th, 2007 · No Comments

The New York Times writes about a new machine being introduced by Andy Bechtolsteim of Sun:

At a high-performance computing conference in Dresden, Germany, he plans to introduce his newest machine: a supercomputer to be named the Sun Constellation System that will compete for the title as the worlds fastest when installation is complete this year.

A lot of these high-end systems are superego machines, he said, referring to the industry practice of competing for the ranking of the worlds fastest computing mcahine based on a single type of mathematical calculation. Indeed, some of the fastest supercomputers slow to a crawl when they are given types of problems that require the movement of significant amounts of data between processors.

Mr. Bechtolsheim thought he had found a solution to that problem by modifying an industry standard data switch, making it possible for any of the 13,000-plus Advanced Micro Devices Barcelona microprocessors to communicate with each other more than 10 times as fast as with existing switches.
