Unsupported device! Required CL_DEVICE_OPENCL_C_VERSION 2.0 or higher

Jump to solution

I encounter a problem when I execute program from AMD SDK 3.0 on Ubuntu 14.04.

The clinfo reports is attached.

I am sure that A8-7600 is OpenCL 2.0 supported device. However, when I execute the programs SVMBinaryTreeSearch and DeviceEnqueueBFS, it shows Expected Error: Unsupported device! Required CL_DEVICE_OPENCL_C_VERSION 2.0 or higher. Does anybody know how to fix this?

BTW, the driver I installed is from the package linux-amd-14.41rc1-opencl2-sep19.zip, which is downloaded from AMD OpenCL™ 2.0 Driver

As per the above clinfo, both CPU and GPU have been listed as OpenCL 1.2 supported devices [see "Device OpenCL C version"], however, the OpenCL 2.0 samples like SVMBinaryTreeSearch, DeviceEnqueueBFS etc. in APP SDK 3.0 require "Device OpenCL C version" as 2.0 to run them. You may try this Catalyst Omega driver from here Desktop.
