Intel 4.5GHz & 5GHz LinX Stable Club

Any idea if there's going to be a category for EVGA SR-2 owners and using a pair of 6 core CPU's(12 cores/24 threads) and 24 GB of ram onboard?


I've started linx using a 48194 problem size and using 17.75 GB or ram and it's been nearly 20 minutes and hasn't finished the first pass yet....


So i'd kinda hate to need to run it like this for over 400 minutes( about 7 hours) to complete 21 passes...


Yay, first pass completed in just under 20 mins...

This is odd. It should be way faster.
Have you tried switching CPU configs (NUMA and such) to see if it affects the performance?
It takes around 2H for a good Gulftown run with 12GB of RAM (link). You have twice more memory, but also twice more processing power. So I'm not sure what's up.
Mind posting your current run?
12GB LinX run could be an option in your case, I guess... Need more info!
You'd fit into "Over 100 GFlops" category, that's not too bad as is. I'll think about it, though.

Keep in mind though that with larger memory amounts also comes options to calculate larger problem sizes too, wich aren't even available to other LinX users if they don't have 24GB of ram onboard in the first place, so that leaves pretty much everyone running a dual channel memory setup out....


I'll have to see if NUMA is posing a problem performance wise, but the only way i get well above 100GF/sec is by calculating small problem sizes and using much lower memory amounts too...Here the picture using a 48194 problem size at 17.7 GB of ram:




CPU cores floored to 100% at nearly 4.2 Ghz, with each CPU using only 1.35 volts and the temps have a hard time exceeding 60*C with the fans set at 60%, so the system is actually pretty silent, but that's to be expected with water cooling....
