I just installed the latest update of the OpenCL Applications 2017 SDK (the one released a few days ago) and the experimental OpenCL CPU-runtime is no longer working. When I run clinfo, I got a -11 error on clBuildProgram:
Platform Name: Experimental OpenCL 2.1 CPU Only Platform
Number of devices: 1
Device Type: CL_DEVICE_TYPE_CPU
Vendor ID: 8086h
Max compute units: 12
Preferred local atomic alignment: 0
5 errors generated.
The previous Experimental runtime was working fine. I'm using Windows 10 Pro 64 bit, I've Visual Studio 2013 installed (I also installed the Intel OpenCL SDK plugins for VS) and also have the Intel OpenCL CPU-only 16.1.1 runtime (in addition to the AMD drivers with respective OpenCL runtimes).
