armi.utils.directoryChangersMpi module

MPI Directory changers

This is a separate module largely to minimize potential cyclic imports because the mpi action stuff requires an import of the reactor framework.

class armi.utils.directoryChangersMpi.MpiDirectoryChanger(destination)

Bases: armi.utils.directoryChangers.DirectoryChanger

Change all nodes to specified directory.

Notes

filesToMove and filesToRetrieve do not get broadcasted to worker nodes. This is intended since this would cause a race condition between deleting and moving files.

Establish the new and return directories

Parameters

destination (str) – destination directory

open()

close()
