I/O Files

The files which are used or created by mpi_nonh and mpi_mchf can be divided into:
  1. Common files for all nodes, with a single copy cfg.inp stores the configuration lists. Node 0 creates and writes on a cfg.inp file general information about the problem, it is similar to the serial version.

    -rw-r--r--    1 georgio  georgio    114019 Sep 20 00:34 cfg.inp
    

  2. Node dependent files, with a copy per node Each node creates a file with a basename which is the same as in the serial version, with an additional suffix. The suffix is a string which shows the node ID. All files are written into a temporary directory and the processor ID is the most convenient way for referring to each file. Note, that this method ensures that both applications, nonh_mpi and mchf_mpi refer to precisely the same file as the node ID. This is important for using parallel environments which do not explicitly specify the processor nodes.
