Clang on OSX doesn't support OpenMP by default, so I could not compile JtR with OpenMP support without another Clang installation.
However, after looking at the below option, I wonder what the difference is compared to OpenMP mode:
--fork=N fork N processes
If I invoke JtR using
--fork=2, then JtR will run with two processes, executed on different physical processor cores (same as OpenMP)?
