As Intel and AMD take a break from beating each other about the quads, this week we'll turn our attention to software -- specifically, parallel programming. Yes, multicore processors, GPUs and FPGAs are all the rage; but without applications to run on them, they're just pretty etchings.

Will AMD find true happiness in Barcelona? Will Xeon break Opteron's heart? What evil lurks beneath the Front Side Bus? If this sounds like the premise for some weird, high-tech soap opera, that's because it is. The Intel-AMD feud has been going on for over 20 years and the participants show no signs of reconciliation.
