SETI MB CUDA for Linux
riofl:
either today's batch of downloads is supposed to take a very long time for a gpu to complete or i have something going wrong. my fastest gpu is taking 3 hours 2 minutes to reach 85%! and even the others are taking 10 to 15 minutes longer on the other 2 gpus. all 3 gpu temps are also much lower than normal. typically they run 58-65c max load and i have not seen them rise above 50c in several hours.
is this a 'common' experience others are having too today or am i facing something going haywire?

I suggest you try first restarting Boinc, then your computer.

i noticed it was using 100% cpu and that is what tipped me off as well..
i shut down for about 1 min then restarted and that seems to have cured it.
i am wondering though if this is a symptom of something going bad or if it
was just the occasional 'fluke'

Do you still make heavy use of your main graphics card?
What driver do you use?

im using 256.53 driver with cuda 3.1
yes. i have a monitor off both ports of the 285 and one monitor off the 295 and i make heavy use of them though mostly it is in ssh, browser, email , instant msg, text editor windows. the monitors are set up in a zinerama/twinview mixture to get 3 on one desktop.
this is the first time this problem has h appened, and since i power cycled the machine it has not happened since.. although i did do something out of the ordinary yesterday. tried to watch a training seminar video but it wouldnt play. had some wrong version codecs somehow since it did work 2 weeks ago. that may have tossed the vid card into a strange state since i had to kill the player. wound up eating all available memory.i think when something like this happens in the future like with the vid player, ill just power off and start up again to be safe.
