1) Message boards : Number crunching : Nvidia-Ubuntu 14.04 fail with latest kernel (Message 1802796)

New Linux kernel today. Install went fine, GPUs fine,
Seti working fine.

I prefer to keep up with bug fixes. Only one machine
has the nVidia driver problem, and that is only with some kernel releases
in 14.04 LTS. So I occasionally struggle :-)

Two nvidia GPU machines here on 14.04 are updated too
and just work without surprises.

The failed task I mentioned yesterday is failed for 4 others (3 have GPU related messages suggesting reboot same as I got, 1 has complaint about too-old GPU.) So I guess that task failure is nothing I should worry about.

Thanks for the links, The_Matrix.

Updated kernel installed June 28 and installed and ran nvidia-modprobe (same one as before) and X/lightdm stay operational.
So GPU operations have been resumed.

a fair number of GPU tasks validated overnight.

On one task 5008182283 I got:
ERROR: Possible wrong computation state on GPU, host needs reboot or maintenance

which is alarming. I'll be watching all this closely.

My concern is that it is (apparently) the old nvidia-modprobe
that (in 14.04) kills X/lightdm. Why that has not been
updated in sync with the drivers (in ubuntu) is a puzzle.
Someone thinks it's not needed?
Do you have nvidia-modprobe petri33?

Without nvidia-modprobe
the desktop (xfce) comes up fine with either nvidia
driver that 'additional drivers' shows. But boinc cannot see
the GPUs.

I meant Xubuntu, not plain Ubuntu.
16.04 will be officially
marked LTS in the repositories in a month
or so and when it is I'll upgrade.
In hopes it will help with
GPU on boinc. Sensible to do anyway.

Installed the latest (weekly lately) 64bit kernel on CPUid 5766757
Ubuntu 14.04. Did the sequence that has worked for several months
after getting a kernel update:

sudo apt-get purge 'nvidia*' sudo shutdown -h now reboot.... Use settings additional drivers to get nvidia sudo shutdown -h now reboot... sudo apt-get install nvidia-modprobe


It's a very old nvidia-modprobe, but oh well.
X won't start. No graphics.

If I don't install nvidia-modprobe graphics work
but boinc won't find the cards... And yes, I do restart
boinc-client, but that does not help boinc find the cards.

So I aborted the Seti GPU tasks in hand. A lovely bunch of
GPU tasks that I have no way to process right now...
Doing cpu for now on 11 cores.

Finally hit 30 million Seti cobblestones! Essentially all CPU as Seti is mostly not able to use my nVidia GPUs (old or new).

Congratulations to all of you reaching your milestones.

Been focusing on the host with one 750.
Event log shows Seti does not see the GPU
or reqeust GPU tasks
though Einstein and boinc do see the GPU.

Was running with nvidia driver installed by sgfxi.
A 14.04 kernel update resulted in absurd
window/text sizes (very very large)
Apparently noveau driver?
Uh Oh.

Did:
cntrl-alt F2
(to stop X)
(login to text window)
sudo su -
service lightdm stop
sudo apt-get remove `dpkg-query --show '*nvidia*'`
apt-get remove dkms
sgfxi
(and now back to 355 nvidia driver,
and on a reboot to test that this survives reboot,
all is well with boinc on restarting boinc-client).
Still not really getting Seti GPU tasks much if at all,
but oh well.

I've modified app_info.xml on the dual-760's machine
to read along the lines you suggested, but naming
what apps and shared libraries I have right now.

I have no idea if the result is correct or useful.

About the machine with 760's:
There has to be something wrong.
The latest request for Seti tasks says 0 tasks
available. Not even getting CPU tasks.
Puzzling.

einstein is working though.

Tomorrow I'll update that one per Fawkesguy.

Fawkesguy's advice seems to have worked.
Thanks!

Nothing untoward seems to have happened.
Running 355.11 now.

I'll wait a day or two to see what
happens and if nothing notable I will do it
on my other other
machine with modern nVidia.

The nvidia runfile for 7.5 refuses to run because it notices
nvidia_uvm is a loaded module, and quits.
This on Ubuntu 14.04.

I updated /etc/default/grub to boot in text mode
and then 'sudo update-grub'. So I get a text window
and no graphics. But no joy anyway.

I don't know how to get past this issue.
google queries have been no help. So far.

Posted 31 Oct 2015 by Profile David Anderson (not *that* DA)Project Donor
Hmm. https://developer.nvidia.com/cuda-downloads?sid=480386
I downloaded the runfile version ( the .deb could
not be downloaded).
Thanks for the link, TBar

The nvidia download page offered the driver
and optionally the "GPU Deployment Kit"
as a separate download. What is that?
The NVIDIA CUDA INSTALLATION GUIDE
FOR LINUX (capitalization is theirs) does not mention
the Deployment Kit so I'm ignoring the Deployment Kit.

Not sure I want to try installation today.

Posted 30 Oct 2015 by Profile David Anderson (not *that* DA)Project Donor
What I wonder is what is the consequence of
installing the nVidia cuda toolkit on gpu tasks
(seti or others) that are currently running (or stopped)?

Do they just get errored off (ok I suppose) get odd error?
Unpredictable?

Posted 24 Oct 2015 by Profile David Anderson (not *that* DA)Project Donor
The nvidia-cuda-toolkit shows up in synaptic but
installing it would remove 346 and install 340.
I'm not changing anything here just yet.

Note the above list does not show the 346-uvm installed.
Synaptic shows that uvm, but without it the GPU seems
to be doing work. No AP work on hand it appears,
so it is Einstein using the GPU

Posted 19 Oct 2015 by Profile David Anderson (not *that* DA)Project Donor
Read TBar's note more carefully.
Synaptic says (with nvidia as the filter) I have
the following installed and boinc sees the gpu:

nvidia-opencl-icd-346
nvidia-modprobe
libcuda1-346
nvidia-libopencl1-346
nvidia-346
nvidia-prime
bbswitch-dkms
ubuntu-drivers-common
libvdpau1
xserver-xorg-nvidia-lts-vivid
dmraid
