I have a strange trouble with my kernel…
I use laptop Lenovo U430p with Intel Haswell i5 processor with integrated Nvidia GeForce GT 730M (Nvidia Optimus).
Kernel works on NVidia all the time.
Kernel DOES NOT work on Intel CPU all the time.
Kernel DOES NOT works on Intel GPU SOMETIMES (very rarely).
Looks like a bug in a synchronization.
Visual Studio 2012 solution with tests can be downloaded at https://www.dropbox.com/s/xwfwoq7v7ywd13x/MyNN.zip

Can anyone reproduce this bug?
Is there bug in my code instead of the bug in Intel OpenCL implementation?
Any ideas about how to enlight this bug?
I have COMPLETELY no ideas how to investigate this issue…
ps. addition - I use C# with OpenCL.Net.
pps. I use actual version of Intel OpenCL SDK.
