You'll need a new BOINC 7.6.12(+) built after October 5th 2015, as that's the date my new AMD GPU detection code got added to the 7.6 branch.

This 7.6.12 for Ubuntu was built on October 31st. You can also add Locutus of Borg's PPA to your system's Software Sources and get frequently updated builds from there.

Don't think any of the Official Ubuntu/Debian or Locutusofborg Boinc's are built from the 7.6 head, But the 7.6.12 tag, any 7.6.12 builds will be just that, and not 7.6.12(+) builds, you'll have to wait for Boinc 7.6.14 for your AMD GPU fixes to be included.

Yeah, you're probably right. Could've hoped though, as it's quite easy to build multiple instances of a versions number by editing versions.h

What i have tried so far.

- sudo apt-get update
- sudo apt-get dist-upgrade
- sudo apt-get install lib32gcc1
- sudo aticonfig --initial --force
- reboot

Also made links to libOpenCL.so and libOpenCL.so.1

- sudo aticonfig --initial --force
- reboot


Boinc still refuses to detect my GPU.

One thing is for sure if Linux wants to become a windows replacement it has to get more user friendly.

This is very annoying.

What Linux distro are you running now? Where did you get Boinc 7.6.12 from? What Boinc packages did you install?

Boinc tells no usable GPUs found.

Wasted 4 hours now.
Very nice.

Nothing wrong with the Linux OpenCL, the Problem is with BOINC not seeing OpenCL.
The only suggestion I can make besides having libOpenCL.so in usr/lib is to use the Berkeley BOINC 7.4.25 in your Home folder. You will have to set it up the first time by setting execute bits and checking Dependencies with ldd in the terminal, but after that it should work.

What Linux distro are you running now? Where did you get Boinc 7.6.12 from? What Boinc packages did you install?

Linux Mint 17.2, based on Ubuntu 14.04.
Check my thread at Lunatics.

Have you had a read of:

Mike, why not try the sgfxi script I've suggested a few times? I have 5 Linux Mint 17.2 machines, and using the script, I have installed Nvidia drivers successfully every time. No linking of files, no issues whatsoever. OpenCL and CUDA work perfectly. I'm running BOINC 7.2.42 in my home directory. I have no experience using it with ATI cards, but it is my understanding that it works with ATI as well.


http://smxi.org/docs/sgfxi-manual.htm

X needs to be stopped prior to installation.

To install, I run (as root):
cd /usr/local/bin && wget -Nc smxi.org/sgfxi && chmod +x sgfxi && sgfxi

For upgrades, I simply run:
sgfxi

<coproc_debug> please.
Where did you put the symlink to libOpenCL.so.1?
How did you install the drivers? Package manager, Driver thingy, package from AMD, something else?
If package(s), exact name(s) please.

Last time i made symlink i got error wrong ELF class.
So no libOpenCL.so.1 link atm.

With each crime and every kindness we birth our future.

Open Terminal and run the following command:

cd /usr/lib/ && sudo ln -s libOpenCL.so.1 libOpenCL.so

Then restart BOINC.

edit: I'm assuming your card is so new that it doesn't support CAL.

Will try that again after work but IIRC i tried that already and got the message file already exists.

Yes, the card doesn`t support CAL.

Adding LD_LIBRARY_PATH=/lib64:/usr/lib:/lib:/usr/local/lib to etc/default/ did the trick.

But only by the Island Name OpenCL states it's got, not by the model number it has. For that you still need a newer BOINC version.

So now it's seen as an AMD Tonga, not as an AMD Radeon R9 285/R9 380 (Tonga), which is more complete and correct.

Well its the same as on win 7 for me.
At least i can use it now.

Yes, because 7.6.9 doesn't have the detection code built into the client.
7.6.15 got released for testing last night. It does have the new code.

It sounds as though there is something wrong within your usr/lib folder. In one post you say;

Last time i made symlink i got error wrong ELF class.
So no libOpenCL.so.1 link atm.

Then when you tried to make a link and name it libOpenCL.so you got;

Like expected.
File already exists.

Extending the library path out managed to find a valid link to libOpenCL.
For many people simply having a valid libOpenCL.so link in usr/lib was enough to have BOINC see OpenCL with the repository driver. If my experience holds, if you remove the repository driver and install the proprietary driver you will probably have the same problem with BOINC not seeing OpenCL. It is possible with the new LIBRARY_PATH you can avoid that problem though.

Maybe now you can try running 2 instances of OpenCL MBv7 on that card and see if you have the same trouble as in Windows...

I know, i uninstalled the drivers once more and reinstalled it that seems to have fixed that.

It seems i grabbed the non HD5 version.
Lets wait a little.

can anyone give me an example for appconfig to run 2 instances.
I will add my appinfo next weekend at earliest.

This works on my Cayman;

<app_config>
   <app>
      <name>setiathome_v7</name>
      <gpu_versions>
          <gpu_usage>0.5</gpu_usage>
          <cpu_usage>.1</cpu_usage>
      </gpu_versions>
   </app>
</app_config>

I tried the cmdline from the other thread with my Cayman and it worked, but a little slower than with the one I was using. From experience I've found in Linux using the setting -oclfft_tune_wg 128 is faster than using 256. I set it for 128 and it choked. Knowing that wg 128 works I decided to start removing other settings until it worked with wg 128. Removing -oclfft_tune_lr 16 was all that was needed to get it working again. So, I'm using;
-sbs 256 -spike_fft_thresh 4096 -tune 1 64 1 4 -oclfft_tune_gr 256 -oclfft_tune_wg 128 -oclfft_tune_ls 512 -oclfft_tune_bn 64 -oclfft_tune_cw 64
on my Cayman in Ubuntu and it's running around 95% GPU load with 1 MB task. It's hard to tell, but it may be a little faster on the longer tasks than with the old settings, but not by much.
