Dear all,
some of our users reported that they can no longer use our OpenCL-based software on their machines. After some investigations, we noticed that they were using the CPU-only OpenCL runtime with driver version 5.2.*. By "5.2.*" I mean the version number reported by OpenCL as the "Driver version" and not the runtime version reported here for download (like 14.2 and 15.1):

The same binaries of our software are working fine under all the previous versions of the Intel CPU-only runtime (as well as under platforms other than Intel). I've then a couple of questions:
- Where can I download the CPU-only runtime with driver version 5.2.*? At best, I can download runtime version 15.1 which contains the driver version 5.0.0.57 (and it works nicely with our software). It seems that this updated version is installed only with some Intel HD Graphics driver.
- Did you make some specific upgrades from driver version 5.0 to 5.2 that make the newer CPU-only runtime non-backward compatible?
Thanks a lot,
Achille
