What Will Next-Generation Multicore Apps Look Like? ZDNet (07/30/07) Foley, Mary Jo
Computing hardware is becoming increasingly ready to make the switch to multicore processing, but software developers are still struggling with ways to make their software work on multicore processors. "The world is going to move more and more away from one CPU that is multiplexed to do everything to many CPUs, and perhaps specialty CPUs," says Craig Mundie, Microsoft's chief research and strategy officer. "This is not the world that the programmers target today." He says such complex programming is typically only done by those who write core operating systems or for supercomputing. Mundie believes the whole concept of the application will have to be restructured to take full advantage of more powerful, multicore processors. Mundie says that although the microprocessor and hardware systems on the whole have grown in capability, the fundamental concept of the application has not changed. Multicore applications will be more asynchronous, loosely coupled, concurrent, composable, decentralized, resiliently designed, and personal, Mundie says. "We're moving to an era where IT will make a lot of things more personal," he says. One of the big changes will be that computers "become more humanistic," Mundie says. "Your ability to interact with the machine more the way you would interact with other people will accrue from this big increase in power."
