It was disscussed many times already. Look on elapsed times, not CPU ones....

Where do I find 'elapsed time'? I do not see it in the task list area. I went back through stdoutdae.txt, cannot find any task taking under one hour. Am I in the wrong file?

Raistmer:
in stderr of finished result.
On web site go to result info

just wanted to mention, Windows 7 is less than useful for this trick.

I ran this on Windows 7 64bit.  Definitely stupid.  The drivers are old, 179.23 (GPUZ ftw).  From other threads, I assume 180 or something higher is required for this to function properly.  (I figured that out after I realized something was wrong).

That said, I believe the teamwork algorithm was working superbly.  Other than the fact that every CUDA WU errored out almost immediately, there were exactly the right number of tasks for my i7 system; 9 total, with 8 maxing the CPU, and one more only stealing part of 1 cpu long enough to do setup or teardown.  No idea how much it would use while functioning, because they all died quickly.  Also, 2 of the cpu tasks were AP's.

Here's hoping BOINC will fix the scheduling sooner rather than later, or Nvidia will release new drivers for me.  Unfortunately, there's no way I'm going back to Vista.  Win7 is "Vista, done right", imo.

if/when there are drivers that will let this work, is there any chance of a SSE4.1 build?  On that note, I haven't been able to find what the speed difference for SSE4.1 vs SSSE3, SSE3, and so forth are, nor anything regarding if SSE4.2 provides anything useful to the project.  If/when I'm able, I'll certainly experiment to see if 8x SSSE3 on i7 + 1x 9400 GT is faster than just 8x SSE4.1.

Great job and thank you!

My system....
Q6600@2.66
4GB DDR2 1066
GTX260
8600GTS
Boinc V6.6.0

Any ideas why boinc is reporting my system has a GTX260 & 8600GTS, but my account data on berkeley is saying 2 x 8600GTS's ?
I am using the V8 + CUDA apps with great success, how do i know which GPU is being used ?

Also i have tested Boinc 6.6.4 without the AK apps and it runs 2 CUDA wu's plus 4 CPU wu's noproblems. The CUDA wu's are extremely fast, just wish i could use the opt apps along side with the same success. I tried running the AK V8 + CUDA apps on 6.6.4 but Boinc crapped out and would not display any stats even though the wu's were still being processed.
