Reverse Hyperthreading?
 

Some days ago, AMD mumbled something to somebody about coming up with something called "reverse hyperthreading," which would make multiple CPUs look like one to a single-threaded program.


On the one hand, like Intel's hyperthreading, this is unlikely to provide a big general boost. If a computing task is not amenable to parellization, a parallizer isn't going to help at all and might actually hurt a bit.


On the other hand, even if an automated program could do just 50% of what an optimally programmed parallized applications can do, optimally programmed parallized programming is terribly difficult to do, takes a lot of time, and is very expensive. It's like writing machine code as opposed to using a high-level language/compiler. The first is better, but the second is much more affordable and practical.
