"Pork-stuffed Cray parades CEO and product", 13th April 2007, The Register
　http://www.theregister.co.uk/2007/04/13/cray_ungaro_emergent/
"Interview Cray's Peter Ungaro has become fully emergent. Not so much like a fluff-filled executive at a Web 2.0 start-up, but more like a CEO of a manly supercomputing firm ready to brag about his company's latest accomplishments."


"In 2009, Cray begins the “Cascade era” where it will start merging disparate processor technology around a common architecture. The company wants to ship Opteron, Vector, FPGA and massively-multithreaded technology in the same box. Baker will be the first product in this line."

To pull off Cascade, Cray must still design custom compilers that split up applications and send the right code to the right kind of processor. Cray also plans to keep beavering away on a standard version of Linux for its boxes and a lightweight version that's more scalable on the high-end kit."

Close to 250 of Cray's 800 staff work on software at this time."

"ORNL's 'Jaguar' Purring Perfectly", April 5, 2007
　http://www.nccs.gov/news/pr2007/news_20070405_knoxnews.html
"Oak Ridge National Laboratory's revved-up "Jaguar" passed its 72-hour acceptance test with high marks, and the supercomputer now has a peak capability of 119 trillion calculations per second - or 119 teraflops."

"The test runs included a number of real-life applications, including computer codes associated with advanced simulation of materials at the atomic scale, he said."

"One of the material codes had a sustained performance that was 68 percent of the computer's peak capability, Zacharia said. Other codes ran at about 36 percent, he said."

"Later this year, Jaguar will be upgraded again. New processors will be loaded into the cabinets. That will more than double the peak operating capability to about 250 teraflops."

"Within the next two years, the Oak Ridge lab expects to have a new petascale machine from Cray, with a peak capability exceeding 1,000 trillion calculations per second."

PSCでもそうだけど、使われるからこそ必要にせまられて、こういう大規模システム稼働状況可視化ツールが
ユーザサイドで開発されるのでしょう (須藤様、ご紹介有り難うございます)。

"Data shown here concern only "palu", the production version of the XT3 at CSCS and not "gele", the developers system."
言いたいことは解るけど、"palu" と "gele" が気になる。
