I finished one it did not crash

Anonymous platform (NVIDIA GPU cuda42)
Total time 9643.55 seconds
GPU time 8381.75 seconds

collatz v2.05 (cuda31)
Total 8,035.38 seconds
GPU 6,789.84 seconds

don't ask me if its faster these are the reported times.

The cuda42 had a huge stderr_txt output file its pages and pages of it you may want to look at it.

Hi I'm trying the 64bit nivida app it seems to be working fine no problems, i tried to make it crash by suspending it and it did not crash but then I'm only running collatz on my nivida card.

sounds like the "playing nice with others" projects is not working if you don't have the latest drivers upgrade them then report what happens other wise there is a problem.

oh yeah my 9800gt is only work at 75% load why is it only working that much the old app worked at 90% - 95% load.

Tasks take between 2 or 3 more time to complete for the same number of points since yesturday.
With my GT440 and Quadro600. Those cards use OpenCL.
My HD3850 don't have this problem, and it don't use OpenCL.
Is that due to the update?


Isn't OpenCL wonderful? It runs slower and has worse video response!

I'm working on a new CUDA version for CUDA 4.2 which I'm hoping will get the speed back up.


Thanks for the update, I was wondering what you where going to, from what i hear opencl will become the standard when it is optimized for the hardware it will be used on.

In the mean time its good that you are going back to Cuda hopefully it will still run on my 9800gt.

Ignore the ati card its working fine.

However the 9800gt is part app changes effect it, the old app took 2 hour and 45 minutes the new app take 4 hours and 27 minutes, what ever you did you made it slower.

The third wu took 1 hour and 45 minutes what i forgot to say in my last post is that i put the video card back to default setting and the wu after that took 32 minutes.

one thing i have seen by this is overclocking you video card don't make the wu take shorter time it have no effect on the how ling it takes because it the same time.

So in short don't bother overclocking it does nothing.

Hi I was happily crunching away one minute my Ati GPU tasks was taking 32 minutes to complete now they are all taking just over 2 hours complete. I have made no changes all the sames settings/drivers are being used they are just taking 3 time longer.

http://boinc.thesonntags.com/collatz/result.php?resultid=119641137

that was the first task that took 2 hours it has being validated.

http://boinc.thesonntags.com/collatz/result.php?resultid=119641379

This is the second it has not being validated yet, there is a third one being crunched now.

My 9800gt is crunching the new nvidia app no problems however it is taking i think just over 3 hours (it may be longer 4 hours?) to complete when the old app took 2 hours and 45 minutes to complete.
