00031 // Purpose: This file contains the class definition for MPI_Channel.
00032 // MPI_Channel is a sub-class of channel. It is implemented with Berkeley
00033 // stream sockets using the TCP protocol. Messages delivery is garaunteed. 
00034 // Communication is full-duplex between a pair of connected sockets.
