Thanks magum, this make the fork versus MPI part clear! <SNAP> >MPI is never run by default. You usually run a wrapper called mpirun or >mpiexec. Aaah, I see that I've misread a part of the console output: bofh@dev:/opt/JohnTheRipper/run$ ./john /tmp/bcrypt.example Using default input encoding: UTF-8 Loaded 1 password hash (bcrypt [Blowfish 32/64 X2]) Will run 8 OpenMP threads ^^^^^^^^^^^^^^^^^^^^^^^^^ I my mind it said OpenMPI :) Any thoughts about OpenMP versus fork?
