Detailed Description

MPI-realisation of communicator class implementation.

Communicator_impl class provides implementation of communication between parallel processes using MPI. Interface is basically the same as the abstract communicator class.

Communicator::send_init() method creates a channel instance that wraps persistent communication object to receive data from neighbour node located at upward or downward (specified by ipm) in the direction idir. count represents size of buffer by number of elements (bytes).
