Multicore requires changing the OS
Multicore requires a change in the OSJoab Jackson, computerworld, 3/19/2010
At least, it's someone at Microsoft's view...
From computerworld: "With chip makers continuing to increase the number of cores they include on each new generation of their processors, perhaps it's time to rethink the basic architecture of today's operating systems, suggested Dave Probert, a kernel architect within the Windows core operating systems division at Microsoft.
The current approach to harnessing the power of multicore processors is complicated and not entirely successful, he argued. The key may not be in throwing more energy into refining techniques such as parallel programming, but rather rethinking the basic abstractions that make up the operating systems model.
For the talk, he set out to define what a new operating system, if designed by scratch, would look like today. He concluded it would be quite different from Windows or Unix."
