Yes, yes, I know! Use Linux! With that out of the way.
At the moment I'm compelled to have Windows on these servers, so thought while they aren't being used over the weekend I'd have them fold. Ah, now I can feel something else coming on... "Use vbox!" Well, I tried that a while back and didn't have much luck with it. Seeing how it never came close to fully utilizing the processors I simply decided to try sticking with the new V7 client and see how it worked out. Not all that well really. The systems in question are...
Dell R720 with 2x E5-2680 (2.7Ghz)
Dell R820 with 4x E5-4650 (2.7Ghz)
So this should give us a nice apples-to-apples view of how this client handles a 2P and 4P setup. Now with the older client I could get the "baby" 6900 bigadv work units; but these guys only seem to be interested in grabbing 780x's. No matter, we're really after how well they do. So...
R720, Project 7808 (7, 58 , 28) = approx 2m40s TPF
R820, Project 7808 (4, 199, 75) = approx 2m20s TPF
Well shit! That sucks, doesn't it? Especially when you consider that, under Ubuntu with TheKraken running, the R820 could do a 6900 @ 4m30s TPF and the R720 was at 8m20s. THAT is the kind of scaling I was hoping to see; roughly 90% faster. (No idea if that number is right or not, but you get the idea)
Any thoughts as to why this is going so poorly? The processors are all pegged @ 100%. As an aside, I set the 820 to smp64 and it did much worse than leaving it at -1 (which assigned it as smp32)... that was kind of odd.
Anyway... sorry so long. Hope someone finds it of interest.
