Detailed Description

Generic network interface.

Constructor & Destructor Documentation

SST::Interfaces::SimpleNetwork::SimpleNetwork ( SST::ComponentId_t id )

inline

Constructor, designed to be used via 'loadUserSubComponent or loadAnonymousSubComponent'.

Member Function Documentation

virtual void SST::Interfaces::SimpleNetwork::complete ( unsigned int UNUSEDphase )

inlineoverridevirtual

Used during the init phase.

The method will be called each phase of initialization. Initialization ends when no components have sent any data.

Reimplemented from SST::BaseComponent.

virtual void SST::Interfaces::SimpleNetwork::finish ( )

inlineoverridevirtual

Called after simulation completes, but before objects are destroyed.

A good place to print out statistics.

Reimplemented from SST::SubComponent.

virtual nid_t SST::Interfaces::SimpleNetwork::getEndpointID ( ) const

pure virtual

Returns the endpoint ID.

Cannot be called until after the network is initialized.

Returns: Endpoint ID

virtual const UnitAlgebra& SST::Interfaces::SimpleNetwork::getLinkBW ( ) const

pure virtual

Returns the final BW of the link managed by the simpleNetwork instance.

Cannot be called until after the network is initialized.

Returns: Link bandwidth of associated link

virtual void SST::Interfaces::SimpleNetwork::init ( unsigned int UNUSEDphase )

inlineoverridevirtual

Used during the init phase.

The method will be called each phase of initialization. Initialization ends when no components have sent any data.

Reimplemented from SST::SubComponent.

virtual bool SST::Interfaces::SimpleNetwork::isNetworkInitialized ( ) const

pure virtual

Check to see if network is initialized.

If network is not initialized, then no other functions other than init() can can be called on the interface.

Returns: true if network is initialized, false otherwise

virtual Request* SST::Interfaces::SimpleNetwork::recv ( int vn )

pure virtual

Receive a Request from the network.

Use this method for polling-based applications. Register a handler for push-based notification of responses.

Parameters

vn	Virtual network to receive on

Returns: nullptr if nothing is available.; Pointer to a Request response (that should be deleted)

virtual Request* SST::Interfaces::SimpleNetwork::recvInitData ( )

pure virtual

Receive any data during the init() phase.

See Also: SST::Link::recvInitData()

Referenced by recvUntimedData().

virtual Request* SST::Interfaces::SimpleNetwork::recvUntimedData ( )

inlinevirtual

Receive any data during untimed phases (init() and complete()).

See Also: SST::Link::recvUntimedData()

For now, simply call recvInitData. Once that call is deprecated and removed, this will become a pure virtual function. This means that when classes implement SimpleNetwork, they will need to overload both recvUntimedData and recvInitData with identical functionality (or having the Init version call the Untimed version) until recvInitData is removed in SST 9.0.

References recvInitData().

virtual bool SST::Interfaces::SimpleNetwork::requestToReceive ( int vn )

pure virtual

Checks if there is a waiting network request request pending in the specified virtual network.

Parameters

vn	Virtual network to check

Returns: true if a network request is pending in the specified virtual network, false otherwise

virtual bool SST::Interfaces::SimpleNetwork::send	(	Request *	req,
		int	vn
	)

pure virtual

Returns a handle to the underlying SST::Link.

Send a Request to the network.

virtual void SST::Interfaces::SimpleNetwork::sendUntimedData ( Request * req )

inlinevirtual

Sends a network request during untimed phases (init() and complete()).

See Also: SST::Link::sendUntimedData()

For now, simply call sendInitData. Once that call is deprecated and removed, this will become a pure virtual function. This means that when classes implement SimpleNetwork, they will need to overload both sendUntimedData and sendInitData with identical functionality (or having the Init version call the Untimed version) until sendInitData is removed in SST 9.0.

References sendInitData().

virtual void SST::Interfaces::SimpleNetwork::setNotifyOnReceive ( HandlerBase * functor )

pure virtual

Registers a functor which will fire when a new request is received from the network.

Note, the actual request that was received is not passed into the functor, it is only a notification that something is available.

Parameters

functor Functor to call when request is received

virtual void SST::Interfaces::SimpleNetwork::setNotifyOnSend ( HandlerBase * functor )

pure virtual

Registers a functor which will fire when a request is sent to the network.

Note, this only tells you when data is sent, it does not guarantee any specified amount of available space.

Parameters

functor Functor to call when request is sent

virtual void SST::Interfaces::SimpleNetwork::setup ( )

inlineoverridevirtual

Called after all components have been constructed and initialization has

completed, but before simulation time has begun.

Reimplemented from SST::SubComponent.

virtual bool SST::Interfaces::SimpleNetwork::spaceToSend	(	int	vn,
		int	num_bits
	)

pure virtual

Checks if there is sufficient space to send on the specified virtual network.

Parameters

vn	Virtual network to check
num_bits	Minimum size in bits required to have space to send

Returns: true if there is space in the output, false otherwise
