He's serious, right?

There's an article in Chip Design magazine by Peter Claydon, titled Implementing Multi-Core:The Devil is in the Detail. The standard argument that lots of slower processors can get more computing done, and with less power, than one big high-speed CPU.

Of course, this is true if the computing task is embarrassingly parallel. Graphics, packet switching in a router, high volume web services, and so on -- sure, no problem. But if the task is not like this, the serial bottleneck will kill the overall performance. Has the history of Thinking Machines been wiped from everyones memory?

We've known the problems for four decades. Are people still really falling for this stuff?
