Sounds great! Bring it on.

I'd love to participate in the organized testing, don't get me wrong. Based on your spreadsheet though the contributions I could make have already been knocked out. I have2 haswell machines. One windows 7 (x64) and one linux (x64). If I can be of service there just let me know. I set primegrid for no new tasks. As soon as it runs out I'll fire this up and see how it goes!

Does anyone have a good app_info/app_config for using this app? Looks like I'm too late for testing it seperately but I can use it for cleanup work.

I reran the test you were talking about and I get different results. It was particularly noticeable on these PSP LLR tasks. Whether it's started first or not, the oclcudagfnwr appears to have a higher priority. The cpu tasks take the hit on usage (inferred by the increase in completion time). They returned to normal runtimes after giving the card it's own cpu core again. Task manager shows it using a full core by itself. So maybe what you mentioned about it doing other things gives it a boost over other tasks? I guess I could have tried this using something other than another boinc task but they were simply handy. This is on a windows 7 box. Also just checked hwmonitor (by CPUID). The core the card is using is just as warm (low to mid 50s - no overclocking) as the others. This would suggest it's being used just as much. It could be running out of cache on the cpu with the additional task (like it would if running 8 tasks by hyperthreading) but it's partner in crunching is nearly identical (4770k vs 4771) and running 4 PSPs with no hit. It's also a linux box so less junk in the background.

Maybe the card itself is so fast that it actually uses more cpu vs other cards? That would explain everything except the priority.

Ahhh. Good eyes. Much longer to run and significantly less cpu usage. Much appreciated.

That's about the same as what I'm getting in times. OCLcudaGFNWR is the OCL app. At least, that's what gets downloaded with Nvidia GPU (OpenCL) set in preferences.

Using the opencl I can do a WR unit in a little over 56 hours on my titan in DP mode. Haven't tried the cuda version yet. I also haven't had any error outs either. Anyone have and times for the cuda version to compare?

My bad. I missed that he was modifying it.

Would there be any word on how much is left for the cleanup? Nothing on the front page so at least whatever is left is in progress.
10) Message boards : Number crunching : Best CPU for LLR/GFN? (Message 73258)

I believe the haswells perform avx faster, maybe someone with both chips can chime in on that. From personal experience though - the 4770k is overclockable BUT running avx causes the voltage it wants and temps it makes to run through the roof for anything but a very modest overclock. I would guess other haswell k series are similar. I'd save the $20 and just get the 4771. Or a hexcore as axn suggests.
