Seems this is to inform Linux users that it _is_ possible to crunch on computers with nVidia Optimus Technology (which in connection Intel Sandy Bridge technology is a huge pita for Linux users) and what brief steps he did to accomplish this. Sorry to hear the forum can only be used if there is a problem or question associated with the post...

Ok, that I can live with: Simply not click on the notices-tab :)

The reason I also wrote about video, was because I saw it mentioned on one of the mailing-lists some months ago in connection with the notices-tab... seems I probably misunderstood something.

Thanks for your help, Ageless :)

Post:
You could probably make the Notices directory and all files within it read-only, that would stop the notices.

I'll try that, thanks :)

However, the only thing that you get sent is HTML code, thus any pictures therein is just a link. Meaning, you don't get sent the picture.

Well, the picture was showing in the notices tab, so it must have then been retrieved when I clicked on the tab :( This was some months ago, with a previous version, so this behavior might have changed since.

I'd think that just by surfing the internet that you'll use a lot more bandwidth by looking at advertisements than you would ever get through the Notices.

Nope, no advertisements here. That's what AdBlockPlus, Ghostery etc. is for. The limited bandwidth (1GB per 30 days, up and down combined, speed max 10KB/s) is when I'm out of the capital city in the non-western country I now live in, which is quite often. I surf as little as possible then, mostly just checking email.

But that said, I'll ask the developers if there's a off-option coming.

Thanks :)

Post:
Mods: Not sure if this question really belongs in Manager section. If not please move it to appropriate section.

Is there any way to make boinc manager 1) stop getting notices from projects and 2) stop displaying them in the "Notices"-tab in manager?

1) is the most important for me, because of very limited bandwidth. Some might say that isn't a problem since it's just text, but projects can also send pics (einstein has done at least once that I saw) and afaik also video through notices. I don't wish to waste my bandwidth on such things. At least an option to only receive text would be most helpful...

Sorry for resurrecting this one, but during my current trip to a country with decent internet-connections, I found I can very easily replicate this behavior of boincclient (linux / windows, doesn't matter) locking up when trying to connect to internet:

Connect to a router (dhcp / manual, wire / wireless, ISP-dns / router-dns / manual-dns, doesn't matter) so your computer registers it's connected to a network. Disconnect the cable from the router to "the internet" ;) and next time boincclient wants to connect, it's starts locking up. You can't use boincmanager to suspend network activity (I didn't try with boinccmd this time, but I seem to remember that also didn't work).

To get response again from boincclient, first stop boinc-service (I don't have any non-service boinc installation, so didn't check). Then edit "client_state.xml". Locate "<user_network_request>2</user_network_request>" near the end and change the value to "3" and save. Restart boinc-service and all is well again.

My main complaint is that boincclient completely locks up while waiting for connection. Since it obviously has no problem handling multiple processes, why does network-connection seemingly change it into a single-process-only program?

Which DNS Servers do you use?

208.67.222.222 (OpenDNS)
208.67.220.220 (OpenDNS)
8.8.8.8 (Google)
8.8.4.4 (Google)

I realize now the WUs that error out is actually the applications fault, not BOINC directly, but still it bothers me... I only crunch on 3 out of 8 cores on my main system (to make less heat), so should be (and there is) plenty of room left for other things. Still this happens, not only if network gets problematic, but also if (mechanical) harddrive gets busy: Try create a big non-dynamic virtual harddrive for use in virtualbox, say 100GB and watch BOINC-manager get unresponsive and WUs error out or "no finished file" after creation is finished.

Post:
Thanks to both of you, Ageless and mo.v for the quick replies :) I'm almost 100% sure it's not a coincidence, because it happens _every_ time I have network-problems (if I don't suspend computation), but not exclusively then (busy system sounds plausible, like the old "no heartbeat from client"?). Perhaps the asteroids-application can't handle that situation so they fail. Sadly can't investigate further now as I'm preparing for a longer trip, so it'll be some weeks to get back on this. In the meantime I'll micro-manage ;) Still would like to know what log-flags could maybe help investigate this issue...

Post:
I very frequently get network errors, like connection lost, connection reset, etc., because of the very bad internet where I currently live. But why can't boinc-client handle that while trying to connect? Every time I either get lots of "exited with zero status but no 'finished' file" or simply get "Unrecoverable error"! WTF? Why are computation and network linked so much together? Shouldn't they be separate processes which doesn't interfere with each other? Considering how many hours of work I'm loosing (today about 12 hours in 4 WU's) I'd rather not run BOINC then...

This has happened both in various windows and Linux OS's, in various BOINC-versions from 5.x.x - 7.x.x and on different computers. I wasn't bothered by it so much before, because I lived in a 1st world country with ok or better internet so it happened maybe once a month, but where I live now it happens daily, even several times a day if I'm not micro-managing, but all the time we're told we're not supposed to be micro-managing boinc (and I don't want to). The way it is now I have to do just that: Manually disabling computation, before allowing network activity, wait for uploads / downloads / server contact to finish, then disable network activity and enable computation. :(

Example from today (I forgot to disable computation):

To fix this, set the environment variable

You can already disable the GPU for each project.

Go to the project preferences and turn off "Use Graphics Processing Unit (GPU) if available".

Not when the project (Aqua) doesn't know where to enable it in the site-code...

That is because 5.8.16 shows CPU-time, different from 6.6.20's elapsed time (wall clock time). It changed "recently", but I don't know exactly which version.

You should (might?) be able to highlight a task, then click the "Properties"-button on left side and CPU-time should show there...
