Yes the above numbers are for a single core. With OMP (8x) I get actually even lower performance 166 c/s for the faster PBKDF2 impl., but with MPI (8x) I reach 1390 c/s. > Just wait for magnum to do his OpenCL magic ;) Yes looking forward to it and I'm having some more ideas to reduce the effort to crack etype 18 which I will send in a separate email (new thread).
