Thank you all but the problem is solved for weeks. As I mentioned, the key was to not have selected Help Conquer Cancer from World Community Grid.

Apparently the problem could be related to my Nvidia card while handling the Help Conquer Cancer project.

Let see how performs without tasks from that project.

Anyway, thanks for your help ;)

I've just checked it out and it's just the same. Definetely the problem was not in the World Community Grid options :(

Thanks for your time. It could be the World Community Grid or the DistrRTgen. I'll check it in their forums.

By the way. In my version of Boinc there's a bug that prevents the client from detecting use of kb and mouse if they are wireless. Maybe this is interfering in some way...

[Update]

Seems that World Community Grid is not applying the same general options shared across all the projects. I've found in its control panel that the option "Use GPU while computer is in use" is set to yes when is disabled for the rest of projects. Maybe this is the reason why my GPU is occupied when it shouldn't be. I'll check it out.

Sorry if I'm making a trivial question. I've asked the same recently but I'm not sure if it's right or wrong what's happening.

I'm using the latest Boinc client that is available from the Ubuntu repositories (version 7.0.27 x86) in an Ubuntu 12.04.1 64 bits. Plus, I have a Nvidia 450 GTS suitable for CUDA. I've tuned the general options to have less impact in my everyday use of the computer and everything is fine.

If I'm going to be off my desk for a while I choose the option "always use GPU" from the Boinc manager in order to speed up my tasks. Of course, the GPU temperature quickly rises and the system becomes more or less unusable, but I don't care because I'm not gonna use it.

After coming back I put this option in its default value "use GPU as in preferences". After 2 or 3 seconds, I'm already using the computer as usual, even the GPU temperature is around 30ºC. But.... all this is only apparently. Although the system seems stable, if I try to play a YT video, its audio and image are jerky. No matter how long I wait, sooner or later I'm forced to close the session to recover the normal behavior.

¿Is this normal in my computer scenario? ¿Is still processing the GPU despite the change of option? I know this is a minor problem with an easy workaround, but I'm curious :)


Thanks anyway!

Sorry but I think I didn't explain me good. Of course, when the GPU is doing calculations the system becomes almost unusable. In fact, GPU temperature quickly rises until 60ºC, as I expect.

The problem arises just after changing back to operate without GPU. The temperature decreases ok, but even after a few minutes I notice some strange glitches like the one mentioned above in the YT videos. This is what is worrying me, since I believed that I could freely change between this two "modes" without having impact.

Nice, it's good to know the bug is now fixed.

So far I've been proving the workaround I've suggested, but unfortunately I noticed that when I change from "always use GPU" to "use GPU as in preferences", system becomes laggy anyway. For instance, Youtube videos are reproduced like in slow motion hehe. It's not horribly slow but yes a little.

Has this been fixed in the version you mention?


Thanks again!

Hi.

I've just entered in the amazing world of distributed computation and I'm happy to donate my CPU/GPU spare time.

What's happening? I'm running the Boinc client 7.0.27, which I've downloaded directly from the Ubuntu 12.04 official repositories. In the global preferences, by default is marked an option to only enable the GPU while there is no keyboard and mouse activity in a fixed period of time, let say 5 minutes. The problem is after the period of inactivity Boinc never starts to use my Nvidia GTS 450 as is supposed.

By the way, I'm using wireless mouse and keyboard and I think there has already been problems with this kind of devices.

I suppose a valid workaround would be to switch between "always use GPU" and "use GPU as in preferences" as needed, because with the GPU always in use my system becomes laggy.

Any help/advice?


Thanks!
