sorry chris probably not much help only file I can think of is the XML file if you running Anomonous platform when it says cuda count>0.33< for running 3 on the GPU

100 / how many core gives you how much % per core

---

ops mistake last piece

100 / how many units you wish to do expressed as: 0.??

0.25 = 4

0.33 = 3

0.50 = 2

1 = 1

One of my computers is showing "When Boinc running % of time GPU work is allowed 0.00%"

This happened once before, and the cure was to manually edit a particular file. Can someone please remind me which file it is.

Thanks in advance for any help.

That line was only added to the Computer page last March [1], and the wording seems slightly misleading. It's actually a measure of how much GPU work has been done recently, not whether it has been allowed.

It is of course 0.00% for a host like my Pentium-M laptop which doesn't have a usable GPU. It would also be 0.00% for any project which doesn't have a GPU app version for the particular GPU and installed drivers. I'll assume such factors aren't involved for your case, though would rather not have to guess due to hidden computers.

Possible causes for an otherwise usable GPU not being used:

a) Any of several entries in a cc_config.xml file. <no_gpus>1</no_gpus> would certainly do it, as could an <exclude_gpu> or <exclusive_gpu_app> element.

b) A preference setting which says you don't want tasks for the GPU. That's the "Use ATI GPU" etc. settings for the computer's venue on the SETI@home preferences page.

c) BOINC Manager's Activity menu, "Suspend GPU" ticked.

There are probably others I haven't recalled...

I only run Seti & Einstein work on my GPU, yet my line says 0.00%
So clearly broken. :)

Edit: Apropos, my client_state.xml file, where that info should be coming from, says <gpu_active_frac>0.563743</gpu_active_frac> on a <active_frac>0.591852</active_frac> on a total <on_frac>0.162661</on_frac> :)

Edit2: Answer back from development:

SETI@home has yet to update their server code to the change (6 Mar 2014) where we started recording GPU active fraction in the DB.

That explains that.

And my BOINC 6.10.58 do not record <gpu_active_frac> at all:

The <time_stats> section was extensively revised from version v7.0.38 onwards (Autumn/Fall 2012) - I think the gpu version was added then.

I happen to have an old folder from BOINC 7.0.25 & it looks like they added the GPU info even sooner.

<time_stats>
    <on_frac>0.996655</on_frac>
    <connected_frac>0.984028</connected_frac>
    <active_frac>0.999932</active_frac>

    <last_update>1336436160.896650</last_update>

Which as you said has changed greatly since then.

<time_stats>
    <on_frac>0.999997</on_frac>
    <connected_frac>0.999985</connected_frac>

    <gpu_active_frac>0.994169</gpu_active_frac>
    <client_start_time>1400351341.942099</client_start_time>
