I have an ATI 7790 (Bonaire), and Boinc seems not to find it.

Under Scientific Linux (RHEL) 7, I get the following:

This is with fglrx-14.301.1001

I used to get a message that the OpenCL library was not found, which was fixed by symlinking libOpenCL.so.1 to libOpenCL.so.


The "Debian/Ubuntu/Mint/Derivatives - GPU recognition fixes" thread isn't exactly relevant, but waiting for X to start before starting BOINC has no effect, and xhost+ before starting BOINC has no effect.

One hint is that clinfo shows the CPU, but not any GPUs. I have not installed the SDK; I shouldn't need it, right?

What is my next step?

This is with fglrx-14.301.1001

Which according to AMD's release notes and its download page lacks the CAL and OpenCL components. It is only the display driver.

According to the APP SDK download page, yes you need it. Else you miss the necessary driver components and libraries.

Done. I also removed the links to libOpenCL.so, as they are no longer necessary.

However, there has been no change in the behavior.

Where did you see this? I can't find it, and I even did a search for OpenCL on those pages.

I've made a few changes.

First, a new Catalyst Driver came out today. I've also played with xhost+ and exporting COMPUTE:=0, and I can now get clinfo to spot the GPU, and HelloWorld in the SDK runs.

I've added clinfo to /usr/lib/systemd/system/boinc-client.service in the ExecStartPre immediately before boinc is started. The output indicates that right before boinc starts, the script sees the GPU.

However, I get the same message from the boinc log - "No useable GPUs found".

Thanks for your help. It works now.

What I ended up doing was uninstalling fglrx and the SDK and then reinstalling. I modified the service section of /usr/lib/systemd/system/boinc-client.service:

[Service]
Nice=10
User=boinc
PermissionsStartOnly=yes
Environment=DISPLAY=:0
ExecStartPre=/bin/sleep 6
ExecStartPre=/usr/bin/touch /var/log/boinc.log /var/log/boincerr.log
ExecStartPre=/usr/bin/chown boinc:boinc /var/log/boinc.log /var/log/boincerr.log
ExecStartPre=/usr/bin/chmod -R 777 /proc/ati
ExecStartPre=/usr/bin/xhost si:localuser:boinc
ExecStart=/usr/bin/boinc --dir /var/lib/boinc
ExecReload=/usr/bin/boinccmd --read_cc_config
ExecStopPost=/bin/rm -f /var/lib/boinc/lockfile

and it now works.

Thanks for your help.

lol, not that I did much. It was all your own work. :)
