Before contacting the vendor and opening a support ticket, thought I would ask the experts here.

I have been using BOINC for quite a while but this is my first attempt to use a GPU on a Linux platform. I bought an inexpensive AMD 645x card but the Linux drivers are giving me all sorts of problems. My main goal is to use this AMD GPU as a BOINC data processor only; no video processing. The AMD APU and mobo will handle the video.

Hardware:
CPU:AMD C-70
Motherboard: ASROCK C70M1
RAM: 4GB

Video card: XFX Radeon HD6450 with 1GB RAM
from lspci: 01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Caicos [Radeon HD 6450/7450/8450 / R5 230 OEM]

OS: Debian Jessie
Windows Manager: LXDE

After installing fglrx-driver and the AMD Catalyst drivers (tried several Catalyst drivers with similar results), on reboot, the GUI boot fails with a message "Failed to start Light Display Manager" I followed that trail for about two hours before giving up. Uninstalling the drivers through a text console will let me reboot back into the LXDE GUI.

So, before I really dig in and try to figure this out, is there anyone out there why might possibly know how to properly install the drivers for this card and have BOINC recognize it?

Thanks!

Do you have a monitor attached to the GPU, or a VGA dummy connector? As without one of either, I don't think you can get it to be detected.

Edit: If you're not technically handy, they come as pre-made.

I have not used Jessie and fgrlx, nor running a single AMD GPU headless.

There are two links in this message about running headless Radeon R9 290X not detected by BOINC that might help.

But, if you want to get it running quickly i would suggest getting the GPU running in a normal fashion. fgrlx is not easy to work with,especially without X running.

Good luck...

Thanks Jord and Agentb.

I appreciate all of that advice. :-) Removed all files and remnants from fgrlx and old install attempts of Catalyst and associated drivers. Then I connected the monitor to the video card. From text mode I installed the drivers and Catalyst. Going to not worry about making it headless for now. I just want to make it work.

And it booted into X/LXDE... I am one step closer but not quite there yet.

The drivers and Catalyst are installed. But, BOINC doesn't seem to recognize the graphics card. BOINC Manager shows "GPU Missing, Waiting to run (0.00936 CPUs + 1 AMD/ATI GPU)

Here are the important lines from BOINC's Event Log:

It appears to me BOINC is only seeing the GPU embedded in the CPU, and I know that will not work with BOINC.

clinfo seems to see both GPUs:

  Device Type:                                   CL_DEVICE_TYPE_GPU
  Vendor ID:                                     1002h

  Board name:                                    

I tried several things from this post, but the things I tried don't help. Here are a list of my attempts: SLEEP 6 in the startup script; run BOINC as root; several changes to the cc_config.xml (including <use_all_gpus>1</use_all_gpus> and specifying which GPU to use in <coproc>.)

At a loss for the moment, but need to get to work & pay the bills.

Thoughts would be appreciated. Thanks!!!

It's not clear what version of boinc you are running, the later version are MUCH better at GPU detection and logging.

Can you set coproc_debug in event log options, and post the results.

Thank you.

Sure! Here is the entire log immediately after restart.

OK i see that you are running 7.4.23 which is a bit old.

LocutusOfBorg boinc PPA should get a later version.

and then again try the coproc_debug flag.

Edit: also how exactly are you stopping and starting the boinc client? Have you tried restarting the boinc-client from within a terminal window. Assuming Jessie is not systrmd - it will be

/etc/init.d/boinc-client start

Good link but wrong distro :) jessie-backports works better here.

@Ken Notice that you have an OpenCL CPU which is listed in both clinfo and BOINC output.

@Agentb - Didn't realize my version was that old. After my last batch of work finishes I will upgrade. (finger's crossed)

I restart Boinc like this:

/etc/init.d/boinc-client restart

@Juha - Thanks for that. I did notice the OpenCL CPU was listed in both. I'm new to GPU processing in a Linux environment so no good or bad things popped up in my brain regarding that. :-)

@Agentb - Didn't realize my version was that old. After my last batch of work finishes I will upgrade. (finger's crossed)

About two years... significant improvements to GPU detection (waves to Juha) happened at 7.6.22

I restart Boinc like this:

/etc/init.d/boinc-client restart

@Juha - Thanks for that. I did notice the OpenCL CPU was listed in both. I'm new to GPU processing in a Linux environment so no good or bad things popped up in my brain regarding that. :-)

clinfo will report both CPU and GPU so that's a good sign.

I guess you have tried

sudo xhost +SI:localuser:boinc

before restarting?

Yes, I tried xhost to add boinc to the local user ACL, but the client would still not start a GPU workunit.

I did pull down version 7.6.33 from the backport page and built it. But, now can't start the client. Create a seperate thread for that problem here http://boinc.berkeley.edu/dev/forum_thread.php?id=11262

At the least, it seems I am making progress.

[edited] Guess I could have pulled down the binaries for AMD64, maybe would have been easier.

OK, after installing binaries from the backport repository, now the BOINC client doesn't recognize any GPUs

Has it ever recognized? - i guess it must have, if it has a task.

Check clinfo is running as before from a terminal window (running X) and that is running on the GPU.

OK assuming clinfo is still working, check boinc is a member of the video group

# groups boinc

should show it.

restart boinc from the terminal window.

Edit: probably best to include a pastebin of the full clinfo next, it's not clear to me what drivers were installed.

While i think of it.

Assuming you installed via the repo here check that the icd "amd-opencl-icd" loaders are installed. If not install them.

Yes, boinc is a member of video.

root@luna:/home/ken# groups boinc
boinc : boinc video

It did recognize the APU's GPU before, downloaded a work unit then complained because the GPU could not support any work units (or something to that effect, the BOINC log is somewhere above).

I checked that I had amd-opencl-icd installed, and I do.

Here is a pastebin of my clinfo results:http://pastebin.com/Mmcvh8k2 Looks to me I may have an older version of openCL. Maybe that's the problem?

---

OK I have just re-read the thread, the clinfo looks fine to me.

I notice you mentioned you added

<coproc>
  Some things...
</coproc>

that is not needed and needs removing.

<use_all_gpus>1</use_all_gpus>

Can be kept.

Edit: might easier to post the cc_config.xml file in total.

I'm still curious about the OpenCL dynamic libraries

ldconfig -p | grep OpenCL

but after that i'm short of ideas (you were detecting one device before, but not now)

Edit2: You haven't mentioned this but the get the GPU working with fglrx - there will have been a "sudo aticonfig --initial" at some point.

Odd. I have no <coproc> section and <use_all_gpus> is set to 1. Also, <no_gpus> is set to 0. Here's my cc_config.xml

Here's from ldconfig:

root@luna:/home/ken# ldconfig -p | grep OpenCL
	libOpenCL.so.1 (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libOpenCL.so.1
	libOpenCL.so.1 (libc6,x86-64) => /usr/lib/libOpenCL.so.1
	libOpenCL.so (libc6,x86-64) => /usr/lib/x86_64-linux-gnu/libOpenCL.so

I don't recall the aticonfig, so I ran it; no difference that I could see.

Made a tiny bit of progress. I did this:

xhost local:boinc

And, now BOINC sees the card, but still gets a failure with clGetDeviceInfo

Made a tiny bit of progress. I did this:

xhost local:boinc

And, now BOINC sees the card, but still gets a failure with clGetDeviceInfo

Hmmm. That error can be ignored, for the moment.

Is it picking up GPU tasks?

What is the output from xhost showing now?

BINGO!!!!!!!!
My GPU card is now working on a SETI workunit, with one waiting in the queue.

Must have been a combination of things to get here. One thing I did was add

sleep 10
xhost local:boinc

in the boinc-client script, in the start() proc right after this:

    if [ -n "$DISPLAY" -a -x /usr/bin/xhost ]; then
       # grant the boinc client to perform GPU computing
       xhost local:boinc || echo -n "xhost error ignored, GPU computing may not be possible"
    fi

It is odd... In order for it to recognize and do any GPU work, I must still stop and restart the daemon.

One thing I didn't mention before was the pesky message I received from the BIOS before boot:

The system failed to boot several times."

Never saw that before installing the GPU. I reset the BIOS to defaults and now no message on startup.

And, something that I really do NOT like... X appears to stutter occasionally when the client is running with a GPU work unit running. The screen freezes temporarily and overall is non-responsive. Not sure what is happening...

But, it is indeed processing GPU work units now.

Thanks again!!!
