Message 1364890 - Posted: 5 May 2013, 18:40:40 UTC

I am trying out Ubuntu and have got Seti running on it but can't seem to get any tasks for my GPU. Is it that there are no actual tasks that can be used for this combination? I have been running for a couple of days.

There is a shortage of tasks just now, and has been for a week or more :-(

Your biggest problem is there is no stock app for Linux CUDA, you will have to go to the anonymous platform and optimized apps to run them.

It seems, that I have the same problem... but it is 2 months later.
Is it still the same problem? Is it again the same problem? Or is it another one?

There haven't been any stock GPU app for Linux in ages, maybe never? There's one now but only for AP tasks, just remember to accept AP6 work in settings.

Combination of 2 different problems, there is no stock app currently and we just updated to different apps for Multibeam.

But I have updated the app_info for the X41g CUDA app to allow for v7 crunching and included the stock CPU app as well.

After each of my Linux upgrades I always worry that my Nvidia driver does not match my kernel and so my existing GPU tasks fail out. I use this command to monitor the log file:

less -M -i -p gpu\|nvidia /var/lib/boinc/stdoutdae.txt

and then use the follow command, F, to see what is happening. I leave leave it running in a window as a monitor.
I run primegrid and milkeyway because they have native Linux CUDA support.
I was happy with the recent release of the CUDA program for Seti.
Thanks for the expanded Linux support.

Not very helpful that you're got your hosts hidden, good job you supplied your host ID.

The Error that Boinc reports is:

Have you set your application permissions?

I use the "app_info.xml-cuda_and_stock_cpu_v6andv7"...

That is a Red Herring, you're errored your SETI@home v7 (anonymous platform, nvidia GPU) Wu's out, so your Max Task per Day is only one, the project isn't able to send you any SETI@home v7 (anonymous platform, nvidia GPU) work anyway:

Now it works. Thank you, for your help!

But it works very slowly and there is no work form the server for the CPU. I Think about runing Seti on Windows, until there is a better solution for Linux.

Now it works. ... But it works very slowly ...

'very slowly' means nothing, give real time to complete the tasks and what 'angle range' are they.
CUDA have to be 'much faster' (e.g. x10 speed) compared to CPU

Edit:
You have one completed 'SETI@home v7 Anonymous platform (NVIDIA GPU)':
http://setiathome.berkeley.edu/result.php?resultid=3064315856

Really have too big Run time 84,087.52 (23 h)

At the start of task: 'clockRate = 1032500' (1032 MHz) but it may change during task run -
check if the GPU don't downclock or go in some power-save mode

I don't use Linux but found this (first result on Google for 'Ubuntu Nvidia power-save mode')
Nvidia Powermizer defaults to adaptive mode:
http://ubuntuforums.org/showthread.php?t=1478192

"Nvidia appears to have kindly designed a power saving mode (Powermizer) for our video cards, by clocking down the GPU"


Same GPU and same app (another user):
http://setiathome.berkeley.edu/results.php?hostid=5643864&offset=0&show_names=0&state=4&appid=11

'Run time 2,092.58', 'clockRate = 1071500':

I'm running the same GPU application on a GTX560Ti on this host and it takes around 1200 seconds for a mid range AR task (running 2 tasks in parallel).

This host is running an older Linux version, Boinc 7.0.25, and nVidia driver 310.40. Other than that, I don't see significant differences between the stderr outputs.

The Same Computer under Win XP has Host ID: 4354565
The GPU does the same Work in 18 minutes that needs 24 hours under Linux.

What stops you to fix the Ubuntu Nvidia Powermizer settings?
(it's not true that 'it' "needs 24 hours under Linux", see other people Linux computers)

Using Ubu 10.4 lts and nv280 one wu at a time.
Of the tasks that my 8800GTX has crunched and validated the longest running one took 2257 seconds - 37 min
Its an old slow card compared to new kit.

("nv280" is probably the version of Nvidia driver?)

Did you need to make some adjustments/edits to Nvidia driver Powermizer settings?
(I don't know if 'Powermizer' is the current name that Nvidia uses for this)

What mode/profile for GPU power-saving was set by default?

From my experience with Ubuntu using recent nVidia GPU drivers, even Multibeam tasks require a free CPU core to work correctly. The MB times were twice as fast with 1 free core as opposed to just setting the 'use at most ___ % CPU time' to around 95% hoping that would be enough. It wasn't enough, it needed 1 complete core free. One of these days I'm going to try to install nVidia Driver 266.56 in Ubuntu and see if that makes the same difference it does in Windows. As for now, with 1 free core, my Ubuntu times are about the same as they are in Windows XP.
