LoL, crazy Boinc.

Hi Raistmer.

Tried your files today and when I restarted Boinc, although it recognised my CUDA abilities (I have an NVIDIA 8800GTX) I got computational errors on all my WUs. I don't think the problem was with the files, I suspect the problem is user related  ::)

I have the latest version of Boinc (6.4.5) and after dloading your zip file I extracted the contents into my seti@home projects folder (C:\Documents and Settings\All Users\Application Data\BOINC\projects\setiathome.berkeley.edu, the default location). Have I done the right thing or was something within the zip file supposed to go to, perhaps, the Boinc installation folder? Sorry to be the newb.

Raistmer:
You did right thing, but maybe it's time to suspend CUDA indeed.
Look here:

Raistmer:
To avoid further pollution of science database with wrong but passed validation results I suspend my mod distribution.
SETI CUDA should produce valid resutls or give computation error but not invalid "overflows" when go on large scale use. So, it should be repaired.

lofty:
This is sad news indeed. I guess I will also suspend any further download of WUs. False results are not good: Bad science is worse than no science. I guess I will finish the WUs I have then return to my old optimized non-CUDA apps for the time being. Thanks for your response.

Merry christmas to crunchers everywhere!
