Subject: OpenCl on mesa amd
Hi,
I just installed opencl-mesa and ocl-icd on Manjaro and as well as john
1.9.0.jumbo1-2.
I tried to test rar password cracking with the built in test but I am
running into error messages:
[me@...pc .john]$ sudo john -test -format=rar-opencl
Will run 12 OpenMP threads
Device 1@...pc: Radeon 550 Series (POLARIS12, DRM 3.32.0,
5.2.11-1-MANJARO, LLVM 8.0.1)
Benchmarking: rar-opencl, RAR3 (length 5) [SHA1 OpenCL AES]... (12xOMP)

I checked other opencl formats as well and they show the same error.

ICD loader properties

Any ideas what I can do now? Running the test without opencl works
without a problem.
I am curious why john opens 12 OpenMP processes, when it is supposed to
use the gpu. My cpu has 12 cores.
kind regards,
Bernd
