Issues Installing OpenCL - dx472 - 01-25-2021

I am running hashcat v6.1.1 on MXLinux 19.3 (debian based).

First I ran "hashcat -I" to see what devices are available:


Code:
hashcat (v6.1.1-120-g15bf8b730) starting...

CUDA Info:
==========

CUDA.Version.: 10.1

Backend Device ID #1
  Name...........: Quadro M2000M
  Processor(s)...: 5
  Clock..........: 1137
  Memory.Total...: 4043 MB
  Memory.Free....: 4006 MB

It seems that hashcat can use my GPU, but I want to benchmark both my GPU and CPU to see which will be faster.

Here is the output of "lscpu":

So I installed OpenCL driver Intel® CPU Runtime for OpenCL™ Applications 18.1 for Linux* OS (64bit only) at https://software.intel.com/content/www/us/en/develop/articles/opencl-drivers.html#cpu-section

Then I ran "hashcat -I" again and saw errors:

Code:
hashcat (v6.1.1-120-g15bf8b730) starting...

* Device #2: Outdated POCL OpenCL driver detected!

clCreateContext(): CL_DEVICE_NOT_AVAILABLE

Not sure where to proceed at this point.  What package should I install so that hashcat will recognize my CPU?

RE: Issues Installing OpenCL - undeath - 01-25-2021

remove pocl

RE: Issues Installing OpenCL - dx472 - 01-26-2021

(01-25-2021, 06:34 PM)undeath Wrote: remove pocl

i ran this command with output:

Code:
apt list --installed | grep pocl

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

libpocl2-common/stable,stable,now 1.2-5 all [installed,auto-removable]
libpocl2/stable,now 1.2-5 amd64 [installed,auto-removable]

so then I ran "sudo apt autoremove"  to remove those two results.  I verified they were removed by running "apt list --installed | grep pocl" again. Then I ran the installer for OpenCL from Intel, then "hashcat -I" and got this error message:

Code:
hashcat (v6.1.1-120-g15bf8b730) starting...

clCreateContext(): CL_DEVICE_NOT_AVAILABLE

It will then hang after that.

RE: Issues Installing OpenCL - undeath - 01-27-2021

Do you have the nvidia driver and/or cuda sdk installed? Also make sure you didn't accidentally remove the ICD loader.
