Replying to vince@…:

gcc46 compiled atlas performs 10 to 15 % better than a gcc45 one.

That's not a really big enhancement

That’s your opinion. In the field of HPC, 10% is a lot, especially when all you have to do is change compiler. It’s about half an hour win every four hours. If a user is not concerned with Atlas, he can just opt out by selecting the no_atlas variants and get standard Accelerate framework performance. If he cares about Atlas, then it’s probably to squeeze the most out of his hardware.
