The first hurdle was the 2 vs. 6 size BF_binary discrepancy. Because of it, the program would just get stuck all the time. Once I fixed it in my copy of parallella_bf_fmt.c, I am getting: solar@...aro-ubuntu-desktop:~/2/JohnTheRipper/run$ ./parallella_john.sh -te -form=bcrypt-parallella Benchmarking: bcrypt-parallella, OpenBSD Blowfish ("$2a$05", 32 iterations) [Parallella]... DONE Raw: 865 c/s real, 865 c/s virtual ... which is much less than what you said it would be. So perhaps you forgot to commit multiple changes? Alexander
