  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
