Task does not continue - no CPU nor GPU usage

Hello, my first task has frozen at about 93 %. Task is "ce11". With task manager I see that CPU usage of manager is below 1 %, and no other process needs significant CPU nor GPU.

I used "synchronize" and also stopped / continued it, but no change. I suspect it got into this mode when the computer automatically went into energy saving mode / suspend. I now deactivated this option.

What can I do to let the task finish?

P.S. My computer uses Windows10 Prof. version 1909, and an AMD CPU Ryzen 5 4500U with Radeon graphics.

P.P.S. I just found the messages in "tools" menu: it does not get any tasks:

Hi Karsten, thanks for taking the time to ask about this frozen task. These ce11 tasks have a short duration, so you should see new ones on your device regularly. The low CPU usage is normal.

It is unexpected that it freeze, though, and also that you aren't seeing work for any other projects. We'll look into these two issues. In the meantime, you should be getting more ce11 tasks that work properly, as the first one would have hit its time limit by now.

Hi Tristan,

today it has continued with another task:

28.03.2021 11:22:30 | Charity Engine | Reporting 1 completed tasks
28.03.2021 11:22:30 | Charity Engine | Requesting new tasks for CPU

There are a few relevant settings:

  • Suspend when computer is in use
  • Suspend GPU computing when computer is in use
  • Suspend when non-BOINC CPU usage is above 25%

It looks like you have the first one turned off, but the other two turned on. This is a pretty good way to keep your system very responsive while you are using it, while also allowing work to be done in the background (i.e. when your computer is not busy doing what you are actively using it to do).

You can increase the threshold for suspending work by changing the "CPU usage is above 25%" number to 50% or higher, as you prefer. If your concern is that GPU is being suspended, well, we generally don't have GPU work, only CPU, so this won't really make a difference.

Hallo Tristan,

now I understood, there is an "extended view" option where I can access the missing calculation options.

Thanks, Karsten

Good, I'm glad you were able to work it out! I think I similarly found an issue on our end that might have been preventing your computer from attaching successfully to public research projects. If interested, you can use the Tools -> Synchronize with Charity Engine option in the desktop software to see if it worked. Otherwise, it will automatically synchronize at some point later.

Thanks a lot!

A minour issue: if this  text edit field contains empty lines the cursor keys up/down behave strangely: it is necessary to use left/right insted to traverse the empty line.

Are you using Firefox? I see the same thing with that browser; the up/down arrows skip straight over new lines and go right to the top or bottom. This is not the case using Chromium. Not sure about other browsers. It must be a new feature with a recent release. :)

Yes I only see it with firefox using Windows10. Edge and chrome work (Windows), as well as Firefox and Chrome (Linux)
