subroutine RPN_COMM_init(Userinit,Pelocal,Petotal,Pex,Pey)
OUT
Pelocal: rank of local process Petotal: total number of processes Pex: number of processes along X Pey: number of processes along Y
If not already started, initialize MPI mode and some common blocks (internal use for RPN_COMM routines) and return the topology. If pex and pey are greater than 0, those values will be used and Userinit will not be called.
