protected

Referenced by allocate_unique_id().

Member Function Documentation

node_id sstmac::hw::node::addr ( ) const

inline

Returns: A unique integer identifier

Definition at line 127 of file node.h.

References fail_stop(), and my_addr_.

Here is the call graph for this function:

unique_event_id sstmac::hw::node::allocate_unique_id ( )

inline

Choose a unique (64-bit) integer ID for a message.

This will never be reused except for integer overflow.

Returns: A unique 64-bit integer

Definition at line 142 of file node.h.

References connect_nic(), execute(), handle(), next_outgoing_id_, node(), and send_to_nic().

void sstmac::hw::node::connect	(	int	src_outport,
		int	dst_inport,
		connection_type_t	ty,
		connectable *	mod,
		config *	cfg
	)

virtual

connect

Parameters

src_outport	The outgoing port at the source
dst_inport	The incoming port at the destination
ty	Whether we are configuring the input or output direction
mod	The device currently being connected
cfg	A struct with various special configuration options

Implements sstmac::hw::connectable.

Referenced by set_nic().

protected

Referenced by allocate_unique_id().

virtual void sstmac::hw::node::execute	(	ami::COMP_FUNC	func,
		event *	data,
		callback *	cb
	)

pure virtual

Make the node execute a particular compute function.

This generally causes the function to be executed immediately.

Parameters

func	Enum identifying the type of computation
data	Event object encapsulating data/metadata for computation
cb	The event to execute when kernel is complete

Implemented in sstmac::hw::simple_node.

Referenced by allocate_unique_id().

virtual void sstmac::hw::node::execute	(	ami::SERVICE_FUNC	func,
		event *	data
	)

virtual

execute Asynchronously execute a kernel on some service associated with the node.

This generally enqueues an operation to be performed - not necessarily executing it immediately.

Parameters

func
data

void sstmac::hw::node::fail_stop ( )

Cause the node to crash.

This cancels all future events for this node.

Referenced by addr().

virtual void sstmac::hw::node::finalize_init ( )

virtual

Standard factory type initializer.

Perform extra initialization work after all parameters have been read in.

Reimplemented from sprockit::factory_type.

Reimplemented in sstmac::hw::simple_node.

nic* sstmac::hw::node::get_nic ( ) const

inline

Returns: A handler wrapper for scheduling events to the NIC

References os_, and to_string().

Here is the call graph for this function:

void sstmac::hw::node::send_to_nic ( network_message * netmsg )

Push a network message (operation at the MTL layer) onto the NIC.

Parameters

netmsg

Referenced by allocate_unique_id().

virtual void sstmac::hw::node::set_event_manager ( event_manager * m )

virtual

Set the eventmanager for this scheduler.

Unfortunately, this always has to be called after an event_scheduler is constructed.

Parameters

m	the simulation eventmanager
