Global Settings
===============

In **block2**, we try to minimize the use of global variables.
Two global variables (``frame_()`` and ``threading_()``) have been used for controlling
global settings such as stack memory, scartch folder and threading schemes.

Note that in ``block2`` the distributed parallelization scheme is handled
locally.
