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.
