Sun's Knox turns up at start-up PeakStream

Neil Knox, the leader of Sun Microsystems' lower-end server group until his ouster in 2004, has turned up as chief executive of a start-up called PeakStream.

The company is working on programming technology to let high-performance technical computing customers milk more computing power out of the Cell Broadband Engine and other multicore processors, according to a media invitation.

Kleiner Perkins Caufield & Byers and Sequoia Capital provided venture financing for the start-up. The company plans to emerge from stealth mode in mid-September.
