Overview

The communicator package implements an intermediary to communicate with Chronica's scheduler. The primitives are based on the syntax of the Message Passing Interface (MPI); the communicator runtime always starts with Init and ends with Finalize. At the beginning of each training epoch, Bcast is invoked to broadcast the schedule for the corresponding epoch to all workers.
