Function Documentation

int getXTNodeID	(	int	mpirank,
		int	nummpiranks
	)

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

last updated 10/4/2009 Gengbin Zheng added function CmiCpuTopologyEnabled() which retuens 1 when supported when not supported return 0 all functions when cputopology not support, now act like a normal non-smp case and all PEs are unique.

major changes 10/28/09 Gengbin Zheng

• parameters changed from pe to node to be consistent with the function name
• two new functions: CmiPhysicalNodeID and CmiPhysicalRank

3/5/2010 Gengbin Zheng

• use CmiReduce to optimize the collection of node info
