Subject: RE: Help Compiling John on ARM w/ MPI & CUDA
So I managed to get a few of my cluster systems online. I am going to post some of the data I collected while running a test against a WPA key. Do I need to change the commands I am passing to "mpirun" or do I pretty much have it as optimized as it can be? Also the OpenMP error what is going on in that case and does it concern me at this time?
Thank You

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
