Not a native Intel OpenCL runtime - Miksch - 02-01-2019

Good morning,

I installed the necessary drivers and software explained in www.hashcat.net/faq/wrongdriver for my NVIDIA K1200 graphic card.
Everything went well. When I type the command "hashcat --benchmark" I'm shown following answer:
"* Device #1: Not a native Intel OpenCL runtime. Expect massive speed loss.
             You can use --force to override, but do not report related errors."
Is there anybody who can tell me what's wrong there?

TIA
Best regards
Miksch

RE: Not a native Intel OpenCL runtime - philsmd - 02-01-2019

you probably have a Intel CPU in addition to your GPU.
If you have a CPU with OpenCL support you would need to install the OpenCL driver from software.intel.com to use your CPU too.

Does cracking with your GPU already work for you ?
If you only intend to crack with GPU, you won't need to worry about your CPU driver (and you can ignore it).

please always post the whole device/driver section of the hashcat output, because you should have many OpenCL Platforms/Vendors/Devices etc.

Hi Phil Smile,

thank you for your quick answer!
Yes, I have an Intel graphic controller on board, but I want to use my NVIDIA graphic card, that isn't detected and I don't know why.
The output of hashcat is

* Device #1: Not a native Intel OpenCL runtime. Expect massive speed loss.
             You can use --force to override, but do not report related errors.
No devices found/left.

TIA

I have a complement to maike.
When I type the command clinfo there appears this message
"clinfo: error while loading shared libraries: libOpenCL.so.1: cannot open shared object file: No such file or directory"
When I start "hashcat --benchmark" there is following error hint: "Cannot find an OpenCL ICD loader library." That allthough I have installed nvidia-driver 3.90x.

You need to install OpenCL.
Code:
apt-get install ocl-icd-libopencl1 opencl-headers clinfo

Hi Soxrok2212 Smile,

thank you for your reply. Yes, I know. I've already installed it. But it don't works.
Code:
Package: ocl-icd-libopencl1
Status: install ok installed
Code:
Package: opencl-headers
Status: install ok installed
Code:
Package: clinfo
Status: install ok installed
When I give the command
Code:
hashcat --benchmark
I get this output
Code:
hashcat (v5.1.0) starting in benchmark mode...

Benchmarking uses hand-optimized kernel code by default.
You can use it in your cracking session by setting the -O option.
Note: Using optimized kernel code limits the maximum supported password length.
To disable the optimized kernel code in benchmark mode, use the -w option.

Have you rebooted after you installed? What does clinfo output?

RE: Not a native Intel OpenCL runtime - Miksch - 02-03-2019

Hi there Smile,

I'm just searching for the problem, that my NVIDIA K1200 isn't recognized by hashcat.
In my opinion it seems to be there a problem with the directory
Code:
/run/user/1000/gvfs
The command
Code:
ls -la
shows following line
Code:
d?????????  ? ?       ?         ?            ? gvfs
When I try to delete it I'm shown, that I'm not allowed to do this.
What could this be for a directory, how could I purge it?

TIA
Best regards
Miksch

RE: Not a native Intel OpenCL runtime - philsmd - 02-03-2019

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!

RE: Not a native Intel OpenCL runtime - Miksch - 02-03-2019

Hi philsmd Smile,

thank you for your important hint! I'm completeley new in the theme of ocl, so I didn't mention this mistake myself. Firt time I had installed the official NVIDIA driver. With this driver hashcat worked, but gave me the hint, that it would be the wrong driver and I should have a look at www.hashcat.net/faq/wrongdriver so I uninstalled the official NVIDIA Driver and tried the way given by the faq.
Now I'm going back and try it again Wink.

Thanks a lot! I'm going to report about what happens.
