GPU Only Not Working

Topic 195835
(moderation:
I registered through BOINC. I'm using WCG (CPU-only WUs); I recently switched from GPUGRID to E@H, seeking an alternative for GPU-only WUs.
I told BOINC "No CPU usage" for this project, but I still get pure CPU WUs (they don't use the GPU). I'm ok with WUs that use 0.20 CPU + 1.00 GPUs, but not the 100% CPU ones. Why doesn't the preference block them? How do I configure this?
GPU Only Not Working

What are your settings for:
Run only the selected applications
Binary Radio Pulsar Search:
Global Correlations S5 HF search #1 :
Gravitational Wave S6 GC search :
Run CPU versions of applications for which GPU versions are available
They'll need to be:
Run only the selected applications
Binary Radio Pulsar Search: yes
Global Correlations S5 HF search #1 : no
Gravitational Wave S6 GC search : yes (cannot be changed)
Run CPU versions of applications for which GPU versions are available no
Yes = a check mark on box.
No = blank box.
Only the Binary Radio Pulsar tasks are available as CUDA tasks. The 'normal' Gravitational Wave tasks aren't.
Also make sure that the preferences set are in the same venue as you set the computer into. When you set preferences for Home, but the computer is set for the default, or --- venue, then these do not match.
Thanks. I've updated my

Thanks. I've updated my settings and will report my findings if they're not GPU-only.
Cheers!

@tolafoph how does that work?

@tolafoph how does that work? Can you provide a sample? I'm still getting Gravitational Wave S6 GC tasks (which cannot be disabled), and some of the Binary Radio Pulsar Search ones, that use CPU too.

Wow ashes999, this is exactly the topic I was looking for.
I am a WCG volunteer too and I would like to use Einstein@home only with my nVdia Geforce GTX260.
Ageless, in your post you forgot to mention Gamma-ray pulsar search #1. What about this one?
Instead of using an

Instead of using an app_info.xml. which is quite nerdy stuff, I made a simpler solution, that works fine with me:
Set the project resource share of E@H to 1
Set the project resource share of the other projects (in your case just WCG) to 100 (or even more).
The 20% CPU-use of the GPU-WU seem to be enough to never let you DL any CPU-only WU.

RE: Ageless, in your post

Because that search was only announced yesterday. :-) :-)
I guess when the gamma WU's get rolling out - tomorrow I think, but it could be later in the week - then it may be clearer exactly how to tweak that in further detail. But already my project preferences show the relevant switch:
Run only the selected applications
Binary Radio Pulsar Search: no
Global Correlations S5 HF search #1 : no
Gravitational Wave S6 GC search : yes
Gamma-ray pulsar search #1: no
So you can do what Ageless has thus far recommended, but just add your choice to that. As the current default is 'no' then one needs to flick that to 'yes' by ticking the box.
IIRC Bruce said the initial release rate of gamma WU's was going to be low, to see how things go before any decision to ramp up. No, there was no time line mentioned. That's the routine caution that has applied to other new app releases in the past. :-)
Cheers, Mike.
( edit ) We have Holger Pletcsh to thank for producing the GC algorithm to apply to gravitational wave searches, and his work in adapting that approach to the gamma ray region. Notably the Fermi data largely contains single photon detections ( each of the enormous energy that gammas have ) so the GC method seeks to find regularity amongst other backgrounds, and that just rocks! :-)

Did you double check the preference setting, as well as the venue of the changed preference and of the computer in question?
You can check that in your BOINC event log after a reboot. You should see something like
