Thanks for the response!
I just found the buger. So far, I can run the model without login node.
My problem:
CALL MPI_ATTR_GET (p_all_comm, MPI_IO, iope, liope, p_error)
when I use ' mpirun c0-3 my_program' , after invoking MPI_ATTR_GET, 'iope' is 0. However, when I use 'c3-6' , 'iope' is -2. 'iope' is supposed as the I/O rank. I have to force 'iope = 0' , then it works.
Could anybody tell me the reason why there is different result after invoking MPI_ATTR_GET ?
