41) Message boards : GPUs : detecting GPUs in BOINC on Linux -- UBUNTU 16.04 problem: New release; No OpenCL driver (Message 69652)
Posted 19 May 2016 by Profile jay_e
Post:
Hi,

Here is a contribution for the notes about finding the GPU.

I have a Radeon AMD/ATI GPU and have been crunching happily with POEM, Einstein and SETI.

Before the release of 16.04 (Long Term Release),
Ubuntu handed out an 'fglrx driver that had OpenCL.
sudo apt-get install fglrx-updates

also, explicitly setting the Xhost for BOINC was neededfor Ubuntu 15.10
xhost +si:localuser:boinc

A reference about what makes getting OpenCL complicated is at
http://lists.debian.org/debian-devel/2012/06/msg01108.html but this is probably outdated, now.


In the past there was a problem with what was installed and what BOINC looked for::
libOpenCL.so.1
and
libOpenCL.so

I fixed that manually.

But now, there is a problem.
Ubuntu has deprecated the fglrx driver.
http://ubuntuforums.org/showthread.php?t=2323520&highlight=xenial+fglrx

and refer to
https://tjaalton.wordpress.com/2016/03/11/no-catalystfglrx-video-driver-in-ubuntu-16-04/


In the past I had GREAT trouble getting the driver from AND to work.
Balancing compatible versions is not easy for me - and I tried hit & miss with a lot of scratch paper.
Things to balance
- opencl
- Xorg
- Mesa driver
- Linux kernel

I will try the contibuted code listed in the URL above and see if it works.

HI!

I have used ubuntu 15.10 successfully
there were 2 things I had to do
1) set the xhost for for boinc by doing in your account
xhost +si localuser:boinc

2) there has been startup timing issues for a log time,
I do:
sudo service boinc-client restart

on everey start-up, before I start the boinc-manager

WARNING: read the forums before installing ubuntu 16.04 LTS
A **lot** does not work.
(I use Ratheon/ATI card and the fglrx driver was deprecated. ARGH!)

Found the problem.
I had used vacuum to get out dust.
Had knocked power cable partially loose.
Re-seated cables and now all works OK.

Hi,
I see this on 2 systems
windows vista with BOINC 7.4.42
Ubuntu Linux with BOINC 7.6.2

In both event logs, I see:
7/2/2015 11:04:56 PM | SETI@home | Sending scheduler request: Requested by user.
7/2/2015 11:04:56 PM | SETI@home | Not requesting tasks
7/2/2015 11:04:58 PM | SETI@home | Scheduler request completed

except the other machine is running on Einstein GPU WU - but the
'not requesting' is the same.

I had changed the cc_config.xml in both to:

<cc_config>
   <log_flags>
     <file_xfer>1</file_xfer>
     <sched_ops>1</sched_ops>
     <task_debug>1</task_debug>
  </log_flags>
  <options>
        <fetch_minimal_work>1</fetch_minimal_work>
        <max_file_xfers>3</max_file_xfers>
        <max_file_xfers_per_project>1</max_file_xfers_per_project>
        <report_results_immediately>1</report_results_immediately>
        <save_stats_days>60</save_stats_days>
        <start_delay>60</start_delay>
  </options>
</cc_config>


I was getting aggravated with one project getting only 1 wu and the other
project getting several. Thought this config would resolve.

Anyway.
The side effect was that both machines did not get any GPU work.
The app_configs were set to 1.0 cpu and 1.0 gpu.
So I let the CPU WUs complete - thinking that was the problem.
Nope.
With just 2 WU on a 4-kernel machine, running 100% of kernels,
no GPU work fetched.

I turned on the work_fetch_debug log flag...

I did not understand the entry with SETI "blocked by project preferences"...

I set the fetch minimal back to zero; waited for backoff to wind down.
Did an update.
The Linux machine fetched Einstein GPU WU.
The windows machine fetched SETI GPU WU. after a read of config files and the
backoff completed...

I forgot where to search the BOINC problem 'trac', but I did not see this in the gpu forums.

Problem report needed?

An update..
To rule out other possibilities:
Memory diagnostics - passes 2 loops through all tests
Disc check with the SMART tool - disk passes test
I/O general congestion - started a clamav scan of the partition,
obsered clamav an WU writing activity - but no hangs on switching tabs
and other activity.
Tried % cpu utilization of less than 100% - hang still occurs.
Nothing suspicious seen in /var/logs

Other historical stuff...
I have 2 disks, a SSD and a Spinning disk.
To avoid BOINC eventually wearing out the SSD, I put
/ and swap on the SSD
/var /home and another swap on the spinning disk.
I have not had the hang with this this configuration before.

Want some log tracing? which?

Stumped,

Hi.
A slight variation noticed. I can do a project update. and the pop-up will happen -> sometimes <-.

What is weird about the 'hang' is that it only lasts for about 30 seconds - and then all is fine. And, it seems to happen randomly. It happens whether or nor
files are being uploaded.

I have 11.6 GiB of memory - so I do not think this is the problem...
I'm running 7 of 8 kernels - so there should be processing power left over.

I have seen this on fresh installs of both Ubuntu Mate and Ubuntu (Gnome).

I have done BOINC installs from the BOINC PPA. My version installed are:


sudo add-apt-repository ppa:costamagnagianfranco/locutusofborg-ppa
sudo aptitude update

and start with fglrx-updates as a base...
sudo aptitude install fglrx-updates=2:15.200-0ubuntu0.3

sudo aptitude install boinc=7.6.2+dfsg-0~1343~ubuntu14.04.1
sudo aptitude install boinc-client-fglrx=7.6.2+dfsg-0~1343~ubuntu14.04.1
sudo aptitude install boinc-client-opencl=7.6.2+dfsg-0~1343~ubuntu14.04.1
sudo aptitude install boinc-dev=7.6.2+dfsg-0~1343~ubuntu14.04.1
sudo aptitude install libboinc-app-dev=7.6.2+dfsg-0~1343~ubuntu14.04.1
sudo aptitude install libboinc-app7=7.6.2+dfsg-0~1343~ubuntu14.04.1

( had a GPU not found problem - so I did this to find the libOpenCL.so )

I haven't seen this before...

Question: Can I ignore this - or is it a problem?

Thanks in advance,
Jay

Posted 30 Jun 2015 by Profile jay_e
Post:
greetings...

I had the problem after an upgrade in Ubuntu.
I tried LinuxMint, Ubuntu Mate, and Ubuntu Gnome classic.
I have a Radeon/ATI 7750, so I added the fglrx-updates package from ubuntu and
then added the BOINC ppa

as (I use aptitude):

sudo aptitude install fglrx-updates=2:15.200-0ubuntu0.3

sudo add-apt-repository ppa:costamagnagianfranco/locutusofborg-ppa
sudo apt-get update
(watch for any errors)


aptitude search boinc (Take note of the ppa packages!!)
then I picked up just about all and installed...

sudo aptitude install boinc=7.6.2+dfsg-0~1343~ubuntu14.04.1
sudo aptitude install boinc-client-fglrx=7.6.2+dfsg-0~1343~ubuntu14.04.1
sudo aptitude install boinc-client-opencl=7.6.2+dfsg-0~1343~ubuntu14.04.1
sudo aptitude install boinc-dev=7.6.2+dfsg-0~1343~ubuntu14.04.1
sudo aptitude install libboinc-app-dev=7.6.2+dfsg-0~1343~ubuntu14.04.1
sudo aptitude install libboinc-app7=7.6.2+dfsg-0~1343~ubuntu14.04.1

( this was of 28 June 2015)

and there still was the delay problem. I chose a manual fix - each time
after I start boinc...

sudo /etc/init.d/boinc-client stop
sudo /etc/init.d/boinc-client start

It works for me..

50) Message boards : GPUs : Ubuntu 14.X and AMD GPU HD 7990 (Message 62752)
Posted 26 Jun 2015 by Profile jay_e
Post:
Greetings,

I would like to add a variation and solution..

I was using LinuxMint 14.04 and was crunching merrily with GPU on SETI and Einstein
on AMD/ATI HD7750.
Then, I went on vacation.
When I came back, I did an update and upgrade - an then BOINC said my openCL was not usable.

After reinstalling the drivers from packages (more info at bottom), I upgraded to Ubuntu Mate 15.04 and started over.

I installed with the PPA from:
ppa:costamagnagianfranco/locutusofborg-ppa

Still,
GPU not found.
clinfo said I had openCL for both the processor card and the GPU card.

I added
LD_LIBRARY_PATH=/lib64:/usr/lib:/lib:/usr/local/lib

I also did an xhost local:boinc
and
sudo aticonfig --initial=check

Hurray, the GPU crunches.

FYI
I did not build the AMD driver - but had installed the packages
fglrx-updates and fglrx-amdcccle-updates

FYI, I tried opening up permissions on the lib_openCL in /usr/lib
lrwxrwxrwx 1 0 0 14 Jun 26 01:19 libOpenCL.so -> libOpenCL.so.1
-rw-rw-rw- 1 0 0 27328 Apr 16 12:20 libOpenCL.so.1


Could it possibly be a problem when both CPU and GPU declare that they have OpenCL?

One other oddity in stderrgpudetect.txt; it said:
No protocol specified
Error! Fail to load fglrx kernel module! Maybe you can switch to root user to load kernel module directly

and stdoutgpudetect.txt said
Error: No root privilege. Please check with the system-admin.

I have no idea where the privilege problem happened - or if it is important.

Thanks for all of the above posts to guide me along...

Success!
Boinc sees GPU.
Einstein (& seti) can crunch on GPU.

I had been trying different versions of Ubuntu to see which desktop suits my fancy.
I did not get GPU recognized on Gnome-Ubuntu.
Wiped disk and tried Lubuntu with Lxde.
Did not work at first.
I broke my rule of only testing 1 thing at a time.
Now, I'm not sure which fix was effective.
I believe it was removing boinc-client-fglrx.
but now, the delete and backspace keys don't work and the LxPanel does a segmentation fault at startup.

Oh well. 1 thing at a time.

so it looks like only fglrx-updates is needed to an ATI 7750 recognized by BOINC..

Hope someone else can use this - other than trying to Compile code from Radeon.

Hi Dex....
Hi-ho..

.. About 2 or 3 years ago....
I tried getting the AMD code and compiling.
Tried for about 3 weeks. Trying to get the correct dependencies with openCL
and the video driver(mesa) is a huge pain. I kept getting a blue screen on boot.
I found a blog from a developer that described all of the iterations
he took to get everything working together.


He released the fglrx and fglrx-udtates packages.
I then started with wiping the disk and re-installing all.

The fglrx-updates worked. So much easier than compiling & testing..
I have been crunching successfully on my GPU for over a year through Ubuntu and Debian distributions.

Have you been able to compile and install without breaking something else??
If so, what dependencies/versions did you have to install??
Did you use valgrind?

Currently, I'm trying to see if i can get Lubuntu 14.0 (Lxde) to work for me.
Their system digram showed AMD drivers and OpenCL in their system.

I was trying to get the WxWidgets fix - and am now taking 2 steps back - focusing on getting GPU to work without compiling or ppa

The following are installed:
fglrx-updates-dev (will remove and try without -dev)
fglrx-amdcccle-updates
libegl1-mesa
libegl1-mesa-drivers
libgl1-mesa-dri
libgl1-mesa-glx
libglapi-mesa
libgles2-mesa
libglu1-mesa
libopenvg1-mesa
libwayland-egl1-mesa
fglrx-amdcccle-updates
liblircclient0

I'm going through the /var/logs now and looking for an old problem- links needed to the .so

so far, I can only find an X11 error - it can't find fglrx.dri.so
maybe an X11 init command is needed??

Will sleep on it...
Jay

PS
Started using the BOINC that comes with the Distribution.
But boincclient-opencl was 7.2.42 - may have been incompatible with
the 7.4.37 thet came with LUbuntiu 14.0.4

Greetings!!

I hope I'm not too late for this thread.

I have been crunching Einstein and SETI on my AMD 7750 GPU for years.

Now, I rebuilt my PC with UbuntuGnome ( I was using Ubuntu Studio because I liked Xfce)
and both setI and Einstein won't work.
One of the BOINC event message about the OpenCL driver is missing.

I have forgotten *which* Ubuntu/Debian package to use.

Two general things:
1) previously, I did do sudo /etc/init.d/boinc-client restart
to get through the problem of finding libraries.
2) Other than that - and installing the right packages,
I did nothing else to get all crunching.

OK. Messages. I REALLY want to thank the people at Einstein for extra logs.

Thanks Claggy,
will try it soon. I did get 7.4.37 and the problem is still there - but, to me, looks a lot better.
It only takes one click to get from projects to tasks.
But most of the entries in tasks are not updating.
Got a new Ubuntu release. New problems.
will look through source to find where - or just start with another google or post..

Hi there!!

.............. oh ...............

Pardon me. Having a catharsis.
I should have gotten the PPA and the debian/Ubuntu PPa instead of trying to build it myself.
7.4.37+dfsg-1~utopic1 from the PPA

Ahhh. The WxWidgets are still funky.

It also dawns on me that I did not give you the version of Ubuntu that I am using: Ubuntu 14.10 (Utopic Unicorn)

It looks like I need to go to Ubuntu 15.04 (Vivid) to get the 7.4.38
from locutus.
Perhaps there is a really good reason - like one of the needed library fixes.
I see I can get the Ubuntu ppa at https://launchpad.net/ubuntu/+ppas

My thanks to Locutus.
I would have spent days trying to build something
that still wouldn't work.

There are benefits. I have built my confidence.
I can now go to the dentist today without fear (almost).

I will look at this again after I return from the dentist.
Or maybe a marguerita under a palm tree.

Claggy, thank you!

What make target(s) do you suggest?
1 for compiling and another for compiling & local installing?
I was overwhelmed with all of the targets.

How can I send you a case of beer or some wine?

EGAD!
I left out the word "not"

Seti does not have WU for all types of GPU all of the time.

(Threw in an edit too.)

They also don't give out WU during their maintenace hours -
Usually starting at noon Pacific Time on Tuesdays.

Have fun,
Jay

Hello Eric,

I run Astropulse 7 on seti.

When I get a WU that can run on GPU, the BOINC (advanced view) task page
shows, on the status column, "Running(1 CPUs + 1 AMD/ATI GPU)

You should get something similar.

If not, check the event log at start-up time and verify that BOINC detects your GPU card.

I have an AMD/ATI card and wrote up an app_config.xml file that
limits me to only 1 task running in the GPU at a time,
and having a WU running on the CPU to assist the GPU.

There are a lot of forum events under SETI that give examples of app_config.xml

Hope this helps.

Have fun,
Jay

-- edit --

SETI does have WU for GPU all of the time.
They may be temporarily out. Today, Sunday 18 Jan, there are some - at least for AMD/ATI.

Hi there.

I'm running Linux and BOINC 7.4.36.

I read here https://www.mail-archive.com/boinc_dev@ssl.berkeley.edu/msg07978.html that a fix for the wxwidgets is out.

Well. I don't want to be a pest to the developers, but....

I can do a git clone - but what is the approach to get the 7.4.38 version ??
Do I have to do a "git checkout client_release/7.4/7.4.38" instead?
In addition?

The git man pages can tell me how to do things - I'm cloudy
on what to do.

Yes, I can wait for that release to come out and Debian and Ubuntu to create a package, But where is the fun in that?

Thanks,
Jay

Hello Gary & Chris,

I would like to add some comments about ATLAS.
I will try to be as polite as Jord.

I have done ATLAS WU last year (on Linux) - but not currently.
Atlas has reduced the size requir4ed to to run a WU.
I don't have the URL for the exact forum entry - but it is there.

I ended up using an app_config.xml to limit the number of concurrent Atlas WU.
That was one approach after I resized partitions and made a humonguous disk space available.

I also also had problems with the VM stalling.
I *think* I solved this by setting to task switch to 20 hours and
setting the checkpoint interval to about 20 minutes.
Before you do this, you may want to look at the checkpoint size and weigh
the decision to have less checkpointing.
I was paranoid about having 2 ATLAS task trying to checkpoint at the same time.
I have over 11GiB of memory and I tried running 4 Atlas WU at once - but ended up running only 2 at once.

Another consideration is the large IO done within the VM by ATLAS.
It took my medium-speed (USA standards) DSL about 20 minutes for the WU to satisfy itself. That pushed me to start a second WU about and hour after the first one.

Disclosure: I may be over 60, but I can act like a kid - wanting to see If I can run the project that uses a lot of memory and CPU. I run WCG now.

I hope this helps.
You may have already jumped over your hurdles.
(That is satisfying too.)
Please let me know how it turned out....

Thanks,
Jay
