Detailed Description

Author: Abhinav S Bhatele Date created: October 10th, 2007.

This file is needed because including the cnos_mpi_os.h in a C++ leads to a compiler error. Hence we have defined a wrapper function here which can be called from C++ files

int getXTNodeID	(	int	mpirank,
		int	nummpiranks
	)

getXTNodeID returns nodeID corresponding to the MPI rank (possibly obtained from CmiMyNode()/CmiNodeOf(pe)) passed to it

This scheme relies on using IP address to identify physical nodes written by Gengbin Zheng 9/2008.
