IBM's Blue Gene Runs Continuously At 1 Petaflop 231

Posted by Zonk from the all-i-can-think-is-the-games-you-could-play dept.
An anonymous reader writes "ZDNet is reporting on IBM's claim that the Blue Gene/P will continuously operate at more than 1 petaflop. It is actually capable of 3 quadrillion operations a second, or 3 petaflops. IBM claims that at 1 petaflop, Blue Gene/P is performing more operations than a 1.5-mile-high stack of laptops! 'Like the vast majority of other modern supercomputers, Blue Gene/P is composed of several racks of servers lashed together in clusters for large computing tasks, such as running programs that can graphically simulate worldwide weather patterns. Technologies designed for these computers trickle down into the mainstream while conventional technologies and components are used to cut the costs of building these systems. The chip inside Blue Gene/P consists of four PowerPC 450 cores running at 850MHz each. A 2x2 foot circuit board containing 32 of the Blue Gene/P chips can churn out 435 billion operations a second. Thirty two of these boards can be stuffed into a 6-foot-high rack.'"

Wikipedia Gets State Funding in Germany 157

tmk writes "How can Wikipedia be improved? The German government started a project today to train experts to contribute to Wikipedia. The goal is to write or improve several hundred articles about renewable resources in the Internet encyclopedia. The project is funded by the German Ministry of Nutrition, Agriculture, and Consumer Protection. The German chapter of the Wikimedia Foundation is hiring a Wikipedian to coordinate the efforts. 'The challenge will be to motivate experts who have done good work in other projects to get involved in the community lexicon. As project director Florian Gerlach told heise online, "Such expert reports are usually written, edited, and published in the normal newspapers or even on other websites. But Wikipedia is radically different: articles there continually grow with input from numerous authors, who often remain anonymous. The end product is constantly changing, and third parties can publish their own texts or even change yours." The future authors will therefore receive some training to help them work with Wikipedia.'"
