I'm running now 3 CUDA tasks simultaneously. Last 2 weeks I was running only 2 tasks in parallel, but the RAC gets down to 12000-14000. So I added up one more task to run. I5 runs only 3 tasks at once with 80% load. I will have to look at it for a couple of weeks. If RAC will not go up I'll return it back to run 4 tasks or add up load to 100%. The cards has 192 cores - it is Gigabyte. The temperature of the chip is 68 C.
A decent CPU overclock also helps performance. In this case, I had my i7 set to 4.3 GHz.
And what is the mean daily RAC for the host?
This system has the potential for ~44,000 RAC with the single 295. Unfortunately I don't have enough available bandwidth to feed this system so I have it offline currently.
That's great! I cannot yet make my I5 (sandy bridge) host do more than 16000 daily with GTS 450 1 Gb. Cannot understand why. :(
If you can change to Linux OS, you should be able to get a bit of a boost in GPU performance. Is the video card in a 16x slot that is set to 16x? If you are running any CPU work units, you may try and temporarily disable CPU support to see if that helps performance any. One other thing you can try is to install Process Lasso and give the GPU work units higher priority.
Just a little reminder that RAC as shown by the project is not a good metric for optimization. For example, now BRP4 tasks are again distributed to CPU-only hosts as well which will temporarily decrease the RAC for the GPU crunchers as the average time that it takes our wingman to validate your result will incrrease. After some days it will go back to equilibrium.
Hi,
just an additional information one has to consider. A 44k RAC machine uses roughly 80GB traffic per month. Just make sure your isp has no problems with it.
