If your are trying to create a communicator containing all node local processes
then use MPI_Comm_split_type.

Deal all,
probably I have found the error.
Let's me check. Probably I have not properly set-up colors.
Thanks a lot,
I hope that you have not lost too much time for me,
I will let you know If that was the problem.
Thanks again

Dear R, Dear all,
I do not know.
I have isolated the issues. It seem that I have some problem with:
CALL
MPI_COMM_SPLIT(MPI_COMM_WORLD,colorl,MPIworld%rank,MPI_LOCAL_COMM,MPIworld%iErr)
CALL MPI_COMM_RANK(MPI_LOCAL_COMM, MPIlocal%rank,MPIlocal%iErr)
CALL MPI_COMM_SIZE(MPI_LOCAL_COMM, MPIloca
Those two command lines look exactly the same to me - what am I missing?
