Hi OpenCL expert,
I had to use RHEL6 for my system. I have installed the opencl_runtime_15.1. However, I cannot install intel_sdk_for_opencl_2016_220.127.116.119_x64. It says RHEL7 is needed to support this version. Where can I get the version that runs on RHEL6?
We don't support RHEL6. You might however try to install the following driver https://software.intel.com/en-us/articles/opencl-drivers#latest_linux_driver - you mileage may vary.
Your other option is to use Beignet driver: https://www.freedesktop.org/wiki/Software/Beignet/
