General Development "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."

Doesn't address the main problem

This doesn't address the main problem, which is that user software is not pervasively threaded.

Assigning each processor to a process doesn't fix the single-thread performance ceiling, and it doesn't let single-threaded processes utilize more than one processor when those resources are available.

I don't see what problem this approach intends to solve. Next to user programs, modern OS kernels tend to be comparatively brilliant at multi-threading (not that there's no room for improvement), and nothing in this proposal endows existing user programs with shiny new powers of parallelism.
