The Pittsburgh Supercomputing Center is more than doubling the capabilities of its Cray XT3 supercomputer nicknamed "BigBen" to 21.5 trillion calculations per second, improving its ability to handle the most demanding science projects.
To put that speed in perspective, if everyone of the Earth's roughly 6.5 billion people each did one calculation per second on a calculator, they still would be about 3,000 times slower than the upgraded BigBen.
"The Cray XT3 has proven itself as a massively parallel scientific platform of exceptional capability," said Michael Levine and Ralph Roskies, the Pittsburgh Supercomputing Center's scientific directors, in a statement. "We look forward to new insights into important problems that scientists will produce as a result of this upgrade."
The Supercomputer Center, a joint venture between Carnegie Mellon University, Westinghouse Electric Co. and the University of Pittsburgh, will replace BigBen's existing 2,090 processors with Advanced Micro Devices' top-end Opteron dual-core computer chips. The new chips will double the processor count to 4,180, with a corresponding boost in peak performance while also doubling the computer's memory.
More than sheer speed, the supercomputer's primary technological advance has been the speed at which its processors share information, the center's executives said. Such speed is considered an advantage in projects demanding hundreds of thousands of processors working together.

We moderate comments. Our goal is to provide substantive commentary for a general readership. By screening submissions, we provide a space where readers can share intelligent and informed commentary that enhances the quality of our news and information.
While most comments will be posted if they are on-topic and not abusive, moderating decisions are subjective. We will make them as carefully and consistently as we can. Because of the volume of reader comments, we cannot review individual moderation decisions with readers.
We value thoughtful comments representing a range of views that make their point quickly and politely. We make an effort to protect discussions from repeated comments either by the same reader or different readers.
We follow the same standards for taste as the daily newspaper. A few things we won't tolerate: personal attacks, obscenity, vulgarity, profanity (including expletives and letters followed by dashes), commercial promotion, impersonations, incoherence, proselytizing and SHOUTING. Don't include URLs to Web sites.
We do not edit comments. They are either approved or deleted. We reserve the right to edit a comment that is quoted or excerpted in an article. In this case, we may fix spelling and punctuation.
We welcome strong opinions and criticism of our work, but we don't want comments to become bogged down with discussions of our policies and we will moderate accordingly.
We appreciate it when readers and people quoted in articles or blog posts point out errors of fact or emphasis and will investigate all assertions. But these suggestions should be sent via e-mail. To avoid distracting other readers, we won't publish comments that suggest a correction. Instead, corrections will be made in a blog post or in an article.
