refurbished PowerMac. I still might. The cluster would give me an aggregate 2500 MFLOPS, while a previous-model Mac would give me 3500
how did you get to that #? just wondering. If you're counting on Altivec that's a mistake.
I count Altivec because I'm confident the Apple-modified compiler is capable of producing code for my present algorithm. Even if it can't, I can write it in fairly easily - I'm no stranger to PPC code.
