2nd xeon CPU not detected

[ox_1freak]

Hello,

I'm having issues with my setup, it's got dual Intel Xeon x5675 CPUs with 24 cores each.

I installed the intel opencl driver from here:

https://software.intel.com/content/www/u...pu-section

however only 1 of the 2 processors was detected using the correct runtime, and the other one was using pocl as follows:

when running a scan/crack it would only use device 1 and skip the second one because it wasn't using a native runtime:

###############################################################################################
root@hashcat-cracking-rig:/home/hashcat/Desktop/hashcat_rig# hashcat -b -m 0
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.

* Device #2: Not a native Intel OpenCL runtime. Expect massive speed loss.
            You can use --force to override, but do not report related errors.
OpenCL Platform #1: Intel(R) Corporation
========================================
* Device #1: Intel(R) Xeon(R) CPU          X5675  @ 3.07GHz, 12067/48270 MB allocatable, 24MCU

OpenCL Platform #2: The pocl project
====================================
* Device #2: pthread-Intel(R) Xeon(R) CPU          X5675  @ 3.07GHz, skipped.

so I uninstalled the pocl runtime, uninstalled the opencl runtime, then reinstalled the opencl runtime in the hope that it would make device 2 also use the correct runtime, but now device 2 is not detected at all by hashcat after uninstalling pocl.

Can you please advice if there is a way of applying the correct runtime to all processors, and have them detected by hashcat so to be able to run a scan using all processors with native runtime?

Many Thanks in advance
