P.S. yes, the app needs a full core, cuz i've removed that part of the code that messes around with that on windows.
It also slows down the gpu if you'd run a 4+1 config.
Since it uses a full core, cpu time is actually wall time. It's not like in windows where cpu time << wall time.

OK, replace walltime by CPU time in my prev post. Anyway I interested inthat numbers.

I attached the CUDA start and stop messages from the log, run times are ~ the same I think...
Where to get this PG*.wu test set?

Thik in download area of this site, in benchmarking sector.

I had a look at Hefto99's http://setiathome.berkeley.edu/results.php?hostid=4774614host today, he's now completed two Cuda WU's with Chrunch3r's 608 r06 Cuda app,
both have completed on CPU fallback after 'CUDA runtime ERROR in device memory allocation' in about 15K secs (4hrs),
no credit granted yet.

Hm.. As I expected... Still interesting in (clear) CUDA work with CPU 100% allocation times. I don't understand for what 100% CPU usage is needed for CUDA app indeed. That's why I want to look at elapsed times for tasks I know, not some "wild" task from server...
