Combine CPU and GPU for cracking?

[arkansawdave74]

Hello. I just recently found out about using an intel cpu for cracking and I was wondering if there might be a way to run an intel cpu and an nvidia gpu simultaneously to speed up a crack?

Just make sure that the drivers are correctly installed. Hashcat will automatically detect 2 platforms then.
Use -D 1,2 in your command to use both platforms.

Thank you, Sir. I guess that's why I never saw instructions....because it's automatic. Sure enough, it's working.

Hello,

I have the same question... But when I run 
hashcat -I, I get only the GPU:

Code:

Successfully initialized NVIDIA CUDA library.

Failed to initialize NVIDIA RTC library.

* Device #1: CUDA SDK Toolkit not installed or incorrectly installed.
            CUDA SDK Toolkit 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 11.1.96

  Backend Device ID #1
    Type...........: GPU
    Vendor.ID......: 32
    Vendor.........: NVIDIA Corporation
    Name...........: GeForce GTX 1060 6GB
    Version........: OpenCL 1.2 CUDA
    Processor(s)...: 10
    Clock..........: 1708
    Memory.Total...: 6144 MB (limited to 1536 MB allocatable in one block)
    Memory.Free....: 3200 MB
    OpenCL.Version.: OpenCL C 1.2
    Driver.Version.: 456.71
    PCI.Addr.BDF...: 06:00.0

So, running -D 1 would run on GPU.
I tried -D 1,0 and -D 1,2 but in both cases the index is out of bounds.

What am I doing wrong?

Best regards,
Hendrik

Hello,

after installing w_opencl_runtime_p_2021.2.0.616  the CPU us shown.
Still, I have some issues, but they are not fitting into this thread -- I will open a new one.

Best regards,
Hendrik
