Problems running OpenCL code in Linux on APU

Question asked by cactusflapjack on Jul 21, 2015



I recently built a new system with a desktop A10-7850k, installed OpenSuse 13.2 (64 bit), the Catalyst Driver 15.7 and the AMD-APP-SDK-linux-v2.9-1.599.381-GA-x64.

All OpenCL applications (compiled with gcc 4.8.3 which comes with OpenSuse 13.2) build without errors, but when I try to run them I get a "Segmentation fault" error the moment the first OpenCL function is called, in this case:


clGetPlatformIDs(1, &platforms, &num_platforms);


Is there some environment variable I have to set other than the ones that were automatically set by the SKD install script ?

I am using a 4k monitor and the BIOS has automatically reserved 2GB of system memory for graphics.

Can it be an insufficient memory issue ?


Any suggestions are highly appreciated.
