Finally found the "solution" in Intel's forum:https://community.intel.com/t5/OpenCL-f … 9711#M5258
I'll post it here:
If you're comfortable mucking with the registry, the easiest thing to do is to modify:
HKLM\SOFTWARE\Khronos\OpenCL\Vendors (for 64-bit applications)
or
HKLM\SOFTWARE\Wow6432Node\Khronos\OpenCL\Vendors (for 32-bit applications)
These registry keys should contain one REG_DWORD value for each OpenCL platform. If you change the REG_DWORD value for a platform from 0 to 1 then that platform will no longer enumerate. The nice thing about this method is that if you change your mind, you can re-enable the platform by simply changing the value from 1 back to 0.
Everything works fine for me now.
It seems that SVP4 won't start if there are more than 1 opencl installed. Will there be any fix to it?
