With real supercomputing though, you have to optimize code for the hardware and infrastructure. Code that runs well on a cores on a few connected PCB will not behave the same on networked machines.

It's probably not that efficient due to networking and OS overhead.
Once again...

On top of that I don't think that Stanford is going to optimize code for something along these lines. It'd be interesting to think about how much performance we could get, but historically it really hasn't been about the end user, it's been about the best delivery method for dispensing work units. They're not going to go out of their way to optimize code for this thing until it gets really popular. Think about how long AMD video card users had to wait to get WU's optimized for their cards, and the number of those cards in the world. It certainly won't happen tomorrow... I hope that they can make this a success though, it's a different principle that could bring about more competition in the server market.

Also after reading the article, it seems the $99 board will be a 16-core "13 Ghz" (translates to roughly 812 Mhz per core) board that will make 26 Gigaflops of performance, and if they make $3 Million for the KS, they'll introduce the 64-core that produces 90 Gigaflops. Not a bad effort for their inaugural boards but also brings to mind the Chinese chips... Loongson I think it was? Promised huge performance up front but had issues worse than AMD's cache bug.
