Detailed Description

dummy base class for managers of distributed processes.

NAME: DistrProcManager - dummy base class for managers of distributed processes

DESCRIPTION:

The class is a dummy implementation for basic common functionality for management of distributed processes and parallel programming in a parallel Diffpack environment. The interface allows for usage of different communication languages. The actual implementation of the functionality is in the parallel toolbox to Diffpack, see for instance class "DistrProcManagerMPI".

To initialize the iteration over slaves, call "startIteratorOverSlaves". Without arguments, "startIteratorOverSlaves" initializes the iteration over all slave processes in the group. In an overloaded version indices for the starting and stopping slave in the group can be given.
