Constructor & Destructor Documentation

◆ TCPIface()

gem5::TCPIface::TCPIface	(	std::string	server_name,
		unsigned	server_port,
		unsigned	dist_rank,
		unsigned	dist_size,
		Tick	sync_start,
		Tick	sync_repeat,
		EventManager *	em,
		bool	use_pseudo_op,
		bool	is_switch,
		int	num_nodes )

The ctor creates and connects the stream socket to the server.

Parameters

server_name	The name (or IP address) of the host running the server process.
server_port	The port number the server listening for new connections.
sync_start	The tick for the first dist synchronisation.
sync_repeat	The frequency of dist synchronisation.
em	The EventManager object associated with the simulated Ethernet link.
