I have performance numbers for two servers, but one reports Gflops and the other a SPECfp score. Is there a simple rule of thumb for comparing these two units of measure?


according to this presentation Real Floating Point Apps don’t do many FLOPS, but do lots of data movement, and in case of SPECfp it is circa 30% (based on the 8th slide). But as you can see in the presentation, you cannot really compare the two.
