DISTRIBUTED module

Description

Module that enables distributed parallel computation in Chrono.

This module implements MPI parallel computing algorithms that can be used as a faster alternative to the default simulation algorithms in Chrono::Engine. This module depends on the Chrono::Parallel module.
