Yeah, you have to look at the stderr to see which GPU is crunching.
Or just look at the runtimes:-)
I am calibrating SETI V7 on that system now and had to pull the GT640
as they send various app level cuda tasks (cuda 23, cuda 32, cuda 42, cuda 50)to see which one runs the best on any particular GPU, Well with that slow GT640 in the system it would never calibrate.
So it might stay out for awhile:-)
Once its calibrated I'll bring it back on Einstein
new Intel cpu's are there, AMD has updated their A8/A10 APU's, nVidia GTX 7xx is available.
Most discussions about new hardware take a closer look in gaming performance and deeper sleep states (which is, AFAIK, not the most important ability here), but no one talks about open-CL performance and crunchig speeds.
This is why I ask here: are there first results available which reflect the performance for what we do?
here are my results for BRP5 on ATI 7970 @ 1100MHz:
1WU: 75% gpu load, 5600 sec runtime (needs to be confirmed)
2WU: 89-91% gpu, ~7800 sec runtime. 3400 sec per WU
4WU: 97% gpu, ~13200 sec runtime. 3300 sec pe WU
Now that Seti has both AP and v7 MB apps available for Linux AMD, I have been experimenting with running these tasks alongside BRP5 on the same GPU via a single system.
When I had two AP tasks and one BRP5 task running on a single GPU, the AP tasks had approximately the same run time as if I ran only a single AP task on the GPU and the BRP5 task is running approximately the same run time as if the GPU were only running BRP5 tasks.
I also had a case with a BRP5, AP, and v7 task running on a single GPU and each task ran okay. The v7 tasks have quite a bit of variation in run time from one task to another. I need to do some more testing to see how 1 task runs compared to 2 or 3 tasks per GPU and on the same GPU as the other applications.
GPU load is higher when running AP tasks alongside BRP5. Normally when I run only BRP5, the GPU load is 95% whereas with the AP tasks running, GPU load is 98-99%. Einstein is still my main project but I like to run some AP tasks here and there and I am glad the applications have been ported to Linux and run well alongside the BRP5 application.

Great results!
Which driver are you running currently? I recently upgraded to 13.4 from 12.11 Beta 11.
Well I just did a driver update on a 650Ti GeForce 320.18 WHQL
At the same time I added another GPU cruncher to my grid using a quad-core that was just running Gamma Rays since Jan 2012
I never added a cuda card before because this is the only one I bought from a store and it is in that tiny box with no room for the GeForce card.
But I had a 650Ti under warranty in another box and I sent it back to this certain company using the "RMA" so they sent me a new card first and then I sent them the other card so they could replace the $178 they charged me for the replacement (credit card) since it was under the 3 year warranty.
Well instead when they received it they made up phony excuses and just sent it back to me so as I told them via email I could have repaired it myself but the warranty says they have to do that or replace it.
Well I got it back today and in about 5 minutes I repaired it myself and cut that tiny box open (had to remove the side panel and cut the top off so the 650Ti would fit) and downloaded the new driver and now I have 6 GPU crunchers running!
If I could go back in time I would have just had that certain company send me the over-priced 660Ti since it (and the 550Ti) are better and faster than the 650Ti (SSC 2GB) instead of just having to pay for another 650Ti.
I guess the only good thing is the 650Ti is supposed to run more "fuel efficient" and maybe my next light bill will not be too insane.
So right now this box is running 3 GRP's and one Test4Theory and a pair of BRP5's

Well that link says it is your GeForce GTX 660 tasks when I click on it Tom
