Subject: RE: Help Compiling John on ARM w/ MPI & CUDA
When running it utilizing MPI you do not need to specify the device? ex: "--device=0"
Also, do I have to utilize OpenMPI or will it work with MPICH2?

The --disable-mpi is a no-op, it defaults to disabled.

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
