Ok, its about 2 weeks into the woodcrest experiment. I am starting to form opinions about woodcrest, where it is good, where it is hohum.
First off, woodcrest appears to give really good artificial benchmark. In some cases.
I have noticed a propensity for corporate “bloggers” to somehow turn discussions around to the point where they can do a product placement, or somehow hype their own stuff. Think of things like “so the Yankees will win the series, and this is why our product X is the best”. I kid you not.
So by now you know I ran an old binary and an old test on the Woodcrest and Opteron. I wasn’t impressed with the results, the hype was out of proportion with the reality.
Lets assume that Intel suggests we recompile our code. I pulled down a new GAMESS (the 2-2006 variant), built it with the PGI compiler, though I had to do some option tweaking, it was otherwise OK, and ran it.
