I haven't worked on algorithms in over ten years, so I hope someone can help me out. You can obtain APP (adjusted Peak Performance in Weighted TeraFLOPS) using APP= FPO(1) * F(1) * W(1) + ... + FPO(n) * F(n) * W(n) where FPO(i) = FLOPS per processor F(i) = clock frequency W(i) = weighting factor (in this case .9 as this is an Opteron which I'm pretty sure has a vector unit). I dug up a doc that gives me the WTs, but I can't find anything from AMD that benchmarks the FLOPS of their current CPUs. Could someone tell me from the above algorithm how to determine the FPO given a particular APP number? Or, maybe even better, does anyone have access to FLOP benchies on the Opteron 8000 and 2000 series chips?
