Re: calculating Pi is a better computational benchmark than SPEC2000fp

SPEC mandates the use of several inefficient algorithms for which other, better, code is normally used. It is against the SPEC rules to run any of the better algorithms. It is not against the SPEC rules to have your compiler substitute a better algorithm if you call it a "compiler optimization."

So, if you can afford to pay to have a compiler designed to recognize the SPEC code, and make the obvious substitutions, it is fairly easy to hugely increase SPEC scores.

SPEC, under the current rules, is a joke.

It's funny how Danno thinks calculating Pi is a better computational benchmark than SPEC2000fp.

When you consider that the slowest P4 is 16% faster than the fastest Athlon in SPEC2000FP it's easy to see why he wouldn't want to talk about SPEC.
