fluka-discuss:

I'm also interested in doing the same thing. I do know that one can
write a non-MPI FORTRAN program and put in special calls such as
MPI_INIT, MPI_COMM_RANK, etc. and compile it in a special way that you
will end up with an MPI version of your program. Can the same thing be
done with FLUKA? If the answer is 'yes,' where would one put the
appropriate CALLs?

Joel DeWitt
