Member Function Documentation

void sstmac::hw::packet_flow_switch::add_ejector	(	node_id	addr,
		event_handler *	link
	)

Set the link to use when ejecting packets at their endpoint.

A packet_flow_switch can have any number of ejectors, corresponding to the number of nodes per switch.

Parameters

addr	The compute node address of the endpoint to eject to
link	The link to the compute node for ejection
