Some additional observations. We have some inconclusive results that we need to analyze. Additionally, we need to add additional logic to filter out the cards that we know will not be able to run the application. Once we have done that we will run another round.

The set of work for this first round has been distributed.

Thanks it was fun. Don't work too hard.

Howdy all,

I have also some questions: Should the betas be about the same length ? It seems that in my machine ( Intel 2600, 4.2 GHZ ) the betas run about 2 min OR about one hour

The GPU is recognized by BOINC OK:

12/03/2012 22:12:10 | | ATI GPU 0: AMD Radeon HD 6800 series (Barts) (CAL version 1.4.1646, 1024MB, 991MB available, 2976 GFLOPS peak)
12/03/2012 22:12:10 | | OpenCL: ATI GPU 0: Barts (driver version CAL 1.4.1646 (VM), device version OpenCL 1.1 AMD-APP (831.4), 2048MB)
12/03/2012 22:12:10 | | ATI GPU is OpenCL-capable

Output of the couple of beta results :

Is the both OK ? ( the second one seems to lack the "execution phase" and have only the analysis ) Or is the second one output of the actual beta at all ?

Sorry if there is some simple logic behind the two separate execution times, I have not had time to read any beta announcement infos

I would hazard to say the first is GPU and the 2nd CPU WU's.

Tho I could be wrong.




D-man you type too fast.

Do you have your GPU set to "use GPU while computer is in use"?
