Great info. I really appreciate the work you're doing.
Here are some times for 3 versus 4 WU
7970
11500 3WU 146.5k/day
15500 4WU 144.9k/day
GTX 780
11000 3WU 153.1k/day
14500 4WU 154.9k/day
There is virtually no difference between 3 and 4 at a time except WuProp goes up faster with 4 - the reason I changed :D I'm running the clocks at 1050.
I'm reserving 4 threads in all cases. The 7970 could be cut back to 1 or 2 and shouldn't have any effect ... VERY little CPU usage. The GTX 780 however IS using a full thread per WU.
and nVidia doesn't care.

nVidia has decided that since there is nothing in the OpenCL specs about whether kernels need to truly run asynchronously, unless there are more OpenCL command queues instantiated than there are CPU cores, it will run the kernel in synchronous mode which means the CPU will wait for the kernel to finish. That uses 100% of the CPU even though it really isn't doing anything but waiting. While many have complained about it, the excuse thus far has been.... OK. There hasn't been any and that's pissing many people off. Of course, nVidia would rather everyone use CUDA since that is proprietary and requires nVidia hardware. The CUDA apps use asynchronous kernels so my guess is that it is a marketing ploy. First they push OpenCL to get AMD to abandon CAL and Brook+ and then they change the drivers to encourage people to use CUDA. AMD's OpenCL compiler still has lots of bugs so nVidia doesn't feel threatened there. That, and AMD seems only interested in gamers now.[/rant]
This is why I have never liked nVidia. As a company, they are and always have been..... Assholes.
I can only second Slicker's and F$'s rants about nVidia; their cards/chips are much more expensive than AMD's and at the same time a lot slower when it comes to brute force TFLOPS. Add to that their crappy policy with OpenCL: a standard they actively took part in its design in the Khronos Group IIRC, in contrast to AMD, and then crippled on their own hardware due to crappy marketing reasons.
Well, I guess they argue someone has to keep buying their totally overpriced Quadro and Tesla product lines running CUDA... :mad:
And they still claim to be the world market leader in visual computing professional equipment, somehow I find that hard to believe... But then again it could be the traditionalists in businesses and research using GPU computing equipment for construction/design never buy anything else than NVidia equipment. :confused: :eek:

Well the poem gpu app is running on my phone 640 and 650ti with no problems
App_config.xml is what is needed. I believe I have one posted in the app_config.xml section, sorry not connected to home machine or I would post it here.
Sounds like you found it, for others http://http://www.setiusa.us/forumdisplay.php?167-Project-App_Config-Files
