SetupCartesianTopology()

int SetupCartesianTopology	(	pcpp::CommunicatorType &	parallelCommunicator,
		pcpp::ParallelTopologyInfoType &	topologyInfo,
		pcpp::CommunicatorType &	topoCommunicator,
		std::ostream &	messageStream
	)

Sets up a communicator with Cartesian topology.

This function takes an input communicator, and produces a communicator with Cartesian topology. A pcpp::ParallelTopologyInfoType object specifies the specific mapping, configuration, or dimension restrictions to use in the creation of the topology.

Parameters

parallelCommunicator	ref to input pcpp::CommunicatorType to partition
topologyInfo	ref to pcpp::ParallelTopologyInfoType that specifies mapping, configuration, or dimension restrictions
topoCommunicator	ref to the returned communicator with Cartesian topo
messageStream	ref to std::ostream for any status messages

Returns

0 on success, 1 otherwise
