Correct. (Disclaimer: I am also not in the HPC crowd.) > There [was] > an MPI implementation of John during the 1.6.x days, and it worked > okay - I used it to some success on an 8-way P-III machine.

I have 5 of them here: ftp://ftp.openwall.com/pub/projects/john/contrib/mpi/ PVM was also mentioned on some occasions, but somehow noone has used it for John the Ripper (as far as I'm aware). I don't think either MPI or PVM should be used for an implementation that would be usable in practice - to actually audit password hashes rather than just demonstrate the concept in a university environment.
