Provided MPI libs, headers and runtime are installed in system paths, you'd use --enable-mpi: ./configure --enable-mpi && make -s clean && make -sj8 You'd run it eg. like this (provided all hosts has one CUDA device #0): mpirun -host host1,host2 ./john -format=md5crypt-cuda -test See doc/README.mpi and doc/README-CUDA magnum No malware was found: Scanned by TiSnetworks E-Mail Security Systems. = No malware was found: Scanned by TiSnetworks E-Mail Security Systems.
