Yes, i think so too. If no one objects then i can do that.Btw, MPI_COMM_SELF and MPI_COMM_WORLD are same in mpiuni/mpi.h#define MPI_COMM_WORLD 1#define MPI_COMM_SELF MPI_COMM_WORLDwhile the fortran version declares these communicators as different. mpiuni/mpif.hinteger MPI_COMM_WORLDparameter (MPI_COMM_WORLD = 1)integer MPI_COMM_SELFparameter (MPI_COMM_SELF = 2)
