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.

Multithreading is much more pervasive in the Windows world than it is in desktop Unix software. Most nontrivial programs are not multithreaded, and definitely not in a manner in which to exploit parallelism in a high-performance manner. And this is what matters as the ability for increases in clock speed to provide performance increases slows. This isn't a matter of seeing a nonzero performance increase over the entire span of your computing experience through SMP, it's no longer finding the explosive growth in the performance of any single task's performance that you've come to expect.
