I was just wondering how well the app works now with concurrent starts.

Let's put it this way. I was running three 3.21 QC on my i7-8700 and rebooted. They all resumed normally without error. So it is solved enough.

Yes CPU was checked for use both places and the QC app. Didn't get any QC tasks both time I tried. Just gpu tasks. The scheduler request was for both cpu and gpu work. I know there is plenty of cpu tasks to farm out. Couldn't explain why I didn't get any work. I'll have to try again without gpu work checked I guess.


At risk of stating trivialities: did you check in the log if by chance it's a matter of disk space (either allocated to boinc, or actually free)? QC tasks are unusually demanding on disk space.

Anyway: thanks for trying to make it work :)

Not an important thing, but are you planning to implement separate badges for CPU points?

Hello, I just got a new error with v3.21. Does anyone have any idea what could be causing it?

Task is available below:

Well the disk space allotted to BOINC is 10GB. Have about 8GB free for BOINC/project use.

That wasn't the issue. Probably the request for both gpu and cpu at the same time. I got loaded up with gpu work on my multiple requests for cpu work along with my normal gpu work. Waiting till I clear out the gpu work and can set only cpu work requested. Will see if that makes the scheduler send me cpu work.

Lots of things don't work the same in 18.04 the way they did on 16.04. I figure the change in GTK and Python is the base cause of why compute doesn't work the same.

Have you carried over the boinc dir from a previous installation?

In any case, try resetting the project.

Unfortunately I tried resetting the project with no luck. This is a brand new installation. gcc and libc6-dev said they were already the most recent version after I sudo apt update'd. Do I need to sudo apt upgrade after sudo apt update?

Can you try installing python-support (if not already?)

I am under the impression that the WUs failing with segmentation fault is the root cause, and other errors are consequences.

CPU tasks do not fail on my HP laptop with SuSE Leap 42.3 which is constantly updated by SuSE. They fail instead on my SUN workstation, also with SuSE Linux 42.3 which is not updated by SuSE, I don't know why. On the other hand, GPU tasks run on the GTX 750 Ti board on the SUN, giving me huge credits.

I tried installing python-support and was able to get different errors!

Here is the link again to the error page:
http://www.gpugrid.net/results.php?hostid=480159&offset=0&show_names=0&state=5&appid=

The abandons are due to completely detaching then adding project again which didn't help.

From what I can tell the error is the same, the segmentation fault in pthread. Try to play around with your gcc installation, e.g. see if you have the latest one, g++, and so on. Ubuntu 18.04 is a widespread distro so it's surprising it doesn't work.
