    when I run a code Like this on cluster with two nodes using one core on each:



    use mpi

    implicit real*8(a-h,o-z)

    call MPI_Init ( ierr )

    call MPI_Comm_rank ( MPI_COMM_WORLD, my_id, ierr )

    CALL MPI_COMM_SIZE ( MPI_COMM_WORLD, NUM_PROCS, IERR )

    print*,my_id

    call mpi_barrier(mpi_comm_world,ierr)

    call MPI_Finalize ( ierr )

    end

     

    It does the first printing , but on mpi_barrier it return error including message: rank 0 unable to connect to rank 1 using business card (port=30776,....)

    I can not use any of the command mpi_bcast, mpi_reduce ,... they all don't work, but it can read from each node and print, but

    It comes to communication, It returns this error



    I use windows HPC cluster




    I have run this code with this version of mpi on win XP and vista PC and laptop computers. please help me pass the conundrum.



    Thanks

    are you building your application using MSMPI SDK or using MPICH?
    are you submitting a job to the cluster with the mpiexec command line?

    please elaborate how you run your job.

    thanks,
