mas, I realize that Opteron has a distinct advantage in SPECfp_rate and I don't see that changing in the foreseeable future. I don't see scores for above 4-way systems on SPEC2006 but there is an entry for SPEC2000. There it seems to tail off pretty rapidly going from 4-way to 8-way or 8 & 16 if you count cores. So how good a predictor is SPECfp_rate when going into large HPC systems? I'd like to understand this better.
