IBMs Power5 Chip Adds New Threading Technology
Technology allows administrators to easily switch back and forth from multi-threaded to single-threaded mode.IBMs upcoming Power5 microprocessor will enable administrators to easily switch back and forth from multi-threaded to single-threaded mode, and will dynamically shift power within the chip as needed by the work being done. The features are part of the Simultaneous Multi-threading technology, or SMT, that IBM is putting into the chip, which is due for shipping in the first half of 2004. Systems containing the chip in the companys eServer iSeries and pSeries will be rolled out throughout the end of 2004, according to Mark Papermaster, director of microprocessor design for IBMs Systems Group. IBM officials are scheduled to make a presentation Tuesday regarding the chips SMT capabilities at the Hot Chips microprocessor conference in Palo Alto, Calif.
Papermaster said the SMT technology in the 64-bit dual-core Power5 will effectively boost user performance fourfold. In the chip, each core will be able to handle two threads simultaneously.
