If files are created or read by individual MPI processes with information local to the process (e.g in the dump function) and more than one process is used (
), the MPI process rank is appended to the file names.
This will avoid problems if processes are using a shared file system.
Files which collect data which are global for all MPI processors will created by the process with MPI rank 0 only.
Users should keep in mind that if the file system is not shared, then a file containing global information
which is read by all processors needs to be copied to the local file system before escript is invoked.
