Detailed Description

Implementation of Communicator with BGNET library.

MPI-realisation of communicator class implementation.

This class is an implementation of Communicator using the low latency library BGNET for Blue Gene/Q. MPI is not used (while possible to initialize for the purpose of using Parallel I/O). Multi-instance option is not available. If setting ENABLE_MULTI_INSTANCE and putting number of instance other than 1, setup() aborts. [29 Jun 2013 H.Matsufuru] Simultaneous use of BGNET and MPI libraries become possible thanks to Takumi Doi's contribution. [21 Aug 2014 H.Matsufuru]

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).
