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