Hi,

I have just install the SDK 2.9 on a test machine WITHOUT GPU, I only want to support OpenCL on the CPU for this test (before switching completely to SDK 2.9/OpenCL 1.2).

The problem is that the platform name remain "OpenCL 1.1" !

(Notice that I also have Intel SDK and NVIDIA SDK... only NVIDIA one is 1.1). I have also look for all the "opencl.dll" ... deleted all the files with version 1.1 (except the one in the NVIDIA folder), but it does not solve the problem.

Thanks

Well.... they mucked this up before and I reported it.

i.e. the SDK had an old CPU OpenCL driver.

If you can find a copy of the 13.4? graphics driver download and open them as an archive (I use 7-zip)

In the Packagers folder you will find the CPU based opencl installer.

Extract it and install it.

I can't confirm which graphics driver it was in because their previous driver downloads isn't working for me.

Just so you know that the AMD CPU opencl 1.2 exists here is some parts of my clinfo (I have intel opencl 1.2 installed as well)
