I'm using i7-3770K Ivy Bridge with HD 4000, and I've installed the latest drivers and the newest OpenCL SDK.
When tried to run the code samples with CPU, it works just fine. However, when I set the '-g' parameter to run with the processing graphics, the device cannot be found hence it exited with code -1 (which is likely caused by failing to create a CL context).
SimpleOptimization, GodRays, and all codes that support Intel Processor Graphics failed to run with the HD4000.
I am using Windows 7 64-bit, MSVS VC++ 2008 express edition.
How do I solve this problem?
