GPU task not running/progressing

[jave808]

Hi,
I'm new to einstein@home and I'm having some trouble with a task that refuses to progress in % while the computer is not in use. I have selected the GPU be in use when the computer is not in use after 1 minute. So I go away and let the PC do its thing and when I come back to check on progress - nothing!  The percentage done hasn't increased!  I can get the task to work by selecting use GPU always but then that interferes with my use of the PC (slow mouse and scrolling around).

Anyone come across this before?

Hi Jave,

That's an interesting one. I haven't used the "suspend in use" option before. I actually just tried it.... I checked the box to say "suspend GPU when computer is in use" and selected 1 minute. My Einstein wu's continued to crunch and even started a new set of wu's after 1 minute. Wiggle the mouse and they don't stop.

It could be that the project preference override the BOINC preferences? You have the same ability to suspend work in your Einstein preferences. Also just check both preferences (BOINC & project) that you don't have anything in the "compute only between" in regards to hours of the day to crunch/not crunch. I never use these myself.

I'd try the project preferences and see how that goes.

Hi Jave what Einstein tasks are you running on you GPU?

Also please not do not run the GCW GPU apps on any card that has 3gb or less, as these workunits can use anywhere up to 3gb and therefore will fail.

I can't help with the issue unfortunately, but it might help to install MSI AFterburner, then you can see if the GPU is being used, it has a graph of GPU usage % which is super helpful.

Currently Gamma-ray pulsar binary search.

Yes, I think I did have one of those that failed. My GTX1050 only has 2GB. Do I select tasks in the Einstein@home preferences?

EDIT: I have deselected GCW apps from running via preferences.

Yep you figured it out. :-)

I'm just going to pick up off this thread..... does anyone know how I can get my cpu to crunch work AND Einstein to crunch at the same time?

I used to set my cpu usage to say 90% which would reserve 4 threads for a gpu, however I now notice that even if I set my cpu usage to 50% (or even 25%) and I want to crunch 2 x Einstein w/u's it will only crunch 1 wu at a time. (So I have the settings at 0.5 to run 2 w/u's concurrently)
 
If I pause ALL cpu work, then multiple Einstein w/u's will crunch.... which is not what I want.
Is it an app_config issue? Am I missing a line to say run multiple tasks? Something like this line?

(max_concurrent>2</max_concurrent)

I'm using this btw -

<app_config>
  <app>
    <name>einsteinbinary_BRP7</name>
    <gpu_versions>
      <gpu_usage>0.5</gpu_usage>
      <cpu_usage>1.0</cpu_usage>
    </gpu_versions>
  </app>

  <app>
    <name>einstein_O3AS</name>
    <gpu_versions>
      <gpu_usage>0.5</gpu_usage>
      <cpu_usage>1.0</cpu_usage>
    </gpu_versions>
  </app>

  <app>
    <name>einstein_O4MDG</name>
    <gpu_versions>
      <gpu_usage>0.5</gpu_usage>
      <cpu_usage>1.0</cpu_usage>
    </gpu_versions>
  </app>
</app_config>

Edit - 2 of my systems are running 2 x Einstein wu's PLUS WCG work with my cpu set to 90% usage but my other systems aren't?? All my systems have the same config file.

I don't use the app_config on Einstein I use the Einstein Preferences as they provide the ability to run multiple tasks.  https://einsteinathome.org/account/prefs/project

I just tested it and I have CPU and GPU tasks running.  I have selected all projects to make sure CPU and GPU tasks available.

Well I tried deleting the file and using the Einstein page but nothing changed.
It's weird because some of my systems are running x 2 wu's fine but others aren't! It will only run x 2 wu's if I suspend ALL cpu work.

You may not have pressed 'update' so your two of your systems may be using an out of date configuration. In Boinc Manager go to the Projects Tab, select the project and click the Update button. This could be the reason for the inconsistency.

The again it could be other factors such as RAM, CPU cache or PCI-e pipelines.

Are all the systems the same or are they different computers? If they are the same it could even be a firmware issue
