Not a native Intel OpenCL runtime

[philsmd]

In my opinion your are completely at the wrong track.

Just look at your clinfo output, it says:

Code:

Platform Vendor                                 The pocl project

this is completely wrong. Why do you even have pocl installed?
Your installation is not correct and pocl shouldn't be installed at all.

The clinfo output must have the NVIDIA Platform Vendor mentioned and pocl of course shouldn't be there.

I would suggest to remove all the alternative drivers (the open source ones too, like mesa/pocl etc) and install the driver from nvidia.com.
Make the clinfo output looking good first, before you try hashcat. It's not a hashcat problem for sure in this case!
