Problems with while running an MPICH job RRS feed

  • Question

  • 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.

  • Was this the same app from the other thread? Where you able to get it working?
