Hardware, Embedded Systems Herb Sutter, a software architect from Microsoft, gave a speech yesterday at In-Stat/MDR's Fall Processor Forum. Addressing a crowd mostly consisting of hardware engineers, he talked about how the software world was ill-prepared to make use of the new multicore CPUs coming from Intel and AMD.

What?

Not support SMP? SMP has worked in Windows AT LEAST since Windows NT 3.51. And even at that, it is one of the few operating systems that can migrate threads (not just whole processes) between processors.

As for the benefits, while applications can take specific advantage of multi-cores, the benefit will be that I can do more and still retain good responsiveness of they system.

Pervasive multithreaded programming model...

Maybe someone start to see why forcing pervasive multithreading on developers was a good (but damn too early) move from Be Inc.

As BeOS shows, when wholy multithreaded, a system get better responsiveness. When running on a SMP machine, it expand performance too.

which bit of 'who's desktop OS' did you miss. You know, 95, 98, ME, XP Home none of which supported
SMP. For further reference see Linux, BeOS and Mac OSX.

Now why do you think most Windows Desktop Apps are single threaded.
