Hashcat on AMD CPU after AMD dropped OpenCL support
Hi peeps, 

I just got my new CPU and wanted to stress test it a little bit by cracking some passwords. However when I try to do that, it just selects my GPU. So I list the available devices and find the following output:
hashcat (v6.1.1) starting...

* Device #1: CUDA SDK Toolkit installation NOT detected.
            CUDA SDK Toolkit installation required for proper device support and utilization
            Falling back to OpenCL Runtime

OpenCL Info:

OpenCL Platform ID #1
  Vendor..: NVIDIA Corporation
  Name....: NVIDIA CUDA
  Version.: OpenCL 1.2 CUDA 11.1.106

  Backend Device ID #1
    Type...........: GPU
    Vendor.ID......: 32
    Vendor.........: NVIDIA Corporation
    Name...........: GeForce GTX 970
    Version........: OpenCL 1.2 CUDA
    Processor(s)...: 13
    Clock..........: 1253
    Memory.Total...: 4096 MB (limited to 1024 MB allocatable in one block)
    Memory.Free....: 3328 MB
    OpenCL.Version.: OpenCL C 1.2
    Driver.Version.: 457.09

Aside from CUDA not being installed (which you can ignore, it doesn't matter right now I think), it doesn't even list my CPU. Now my CPU is an AMD Threadripper 3960x and I read somewhere online how AMD has dropped OpenCL support for their CPUs. :/ 
Is there any way to still use my CPU for hashcat, with or without OpenCL?
Install the intel opencl runtime.

Thank you! That worked. It's kinda weird how that works and I couldn't find this solution earlier. Well thanks!
Hi, how did you trick the hashcat to use Intel OpenCL. I installed  intel-opencl-icd on Debian 10 with AMD Epyc, no complains from OS, but hashcat does not buy it. I got

ATTENTION! No OpenCL, HIP or CUDA compatible platform found.
