How to Enable CPU Platform for OpenCL Applications

amd-processoropencl

I am currently running Ubuntu 16.04 on a machine with an AMD A8-5600K APU and a Radeon R9 270X. The amdgpu driver does not yet support my card and therefore I cannot use OpenCL on my GPU. However, I see no reason why OpenCL applications can't use my CPU.

I've installed every package I can think of – ocl-icd-libopencl1 Install ocl-icd-libopencl1 , ocl-icd-opencl-dev Install ocl-icd-opencl-dev , etc.

I've written a simple application that enumerates available OpenCL platforms and it fails on the clGetPlatformIDs() call. What am I missing?

Edit: I installed the AMD APP SDK as recommended in SE6's answer but no platforms were showing up yet. Running strace revealed that the OpenCL ICD loader couldn't find libamdocl64.so.

Further edit: success! I was able to get it working using the following command:

sudo ln -s '/opt/AMDAPPSDK-3.0/lib/x86_64/sdk/libamdocl64.so' \
    /usr/lib/x86_64-linux-gnu/libamdocl64.so

(Replace /opt with the path you installed the AMD APP SDK to.)

Install the AMD APP SDK from the AMD website you should then see your CPU available as an OpenCL device.

Ok. Figured it out (at least in my case). The libGL.so file in /usr/lib/fglrx is not found by by the linker. Adding

LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:/usr/lib/fglrx

to my ~/.bashrc (or ~/.profile) made it work. This shouldn't be required though because the driver installer adds /usr/lib/fglrx to the /etc/ld.so.conf.d/x86_64-linux-gnu_GL.conf file.

EDIT Note: My previous post blamed this bug on Cinnamon (bug 1483); however, this was incorrect. The solution documented is correct.

The problem originally stems from running SSH with X forwarding (SSH -X) when connecting to the server. This sets $DISPLAY which blocks GPU detection.

Once I realised this it became apparent that due to restrictions in Ubuntu (and probably other distros), BOINC has to be run as the logged-in (via X) user.

Assuming the user is user1:

sudo service boinc-client stop
Change BOINC_USER=boinc to BOINC_USER=user1 in /etc/default/boinc (some parts of the init script can be cleaned up too)
Add "sleep 10" to startup() in /etc/init.d/boinc-client to allow the user to log in (needed)
sudo chown -R user1: /etc/boinc-client/*
sudo chown -R user1: /var/lib/boinc-client
sudo service boinc-client start

BOINC now correctly detects the GPU and crunches work units accordingly.
