       I am trying to run my production run with mpirun and this hangs
      (basically stop writing any files). The processes continue to run
      without any output. 

       I have to kill and restart which again hangs after some time. 

       Does anyone have any problems with this?

       what I am doing is 



      mpdboot -n 1 -f NODEFILE


      nohup mpirun -np 12 
        mdrun_mpi -v -deffnm protein-prod &


      what could have been going wrong here?? What could I try


    Probably something about your MPI installation, or perhaps network
    file system, is poorly configured, but it's impossible for us to
    guess better with the information we have. You should try different
    things and see what works and what does not.
