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]...

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
