Detailed Description

Generic network interface.

Member Typedef Documentation

◆ Handler

template<typename classT , typename dataT = void>
using SST::Interfaces::SimpleNetwork::Handler = SSTHandler<bool, int, classT, dataT>

Used to create handlers to notify the endpoint when the SimpleNetwork sends or recieves a packet.

. The callback function is expected to be in the form of:

bool func(int vn)

In which case, the class is created with:

new SimpleNetwork::Handler<classname>(this, &classname::function_name)

Or, to add static data, the callback function is:

bool func(int vn, dataT data)

and the class is created with:

new SimpleNetwork::Handler<classname, dataT>(this, &classname::function_name, data)

In both cases, the boolean that's returned indicates whether the handler should be kept in the list or not. On return of true, the handler will be kept. On return of false, the handler will be removed from the clock list.

Member Function Documentation

◆ complete()

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

Used during the complete phase after the end of simulation.

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

Reimplemented from SST::BaseComponent.

◆ finish()

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

Called after simulation completes, but before objects are destroyed.

A good place to print out statistics.

Reimplemented from SST::SubComponent.

◆ getEndpointID()

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

◆ getLinkBW()

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

◆ init()

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.

◆ isNetworkInitialized()

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

◆ recv()

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
vnVirtual network to receive on
Returns
nullptr if nothing is available.
Pointer to a Request response (that should be deleted)

◆ recvInitData()

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

Receive any data during the init() phase.

See also
SST::Link::recvInitData()

◆ recvUntimedData()

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

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 14.0.

◆ requestToReceive()

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
vnVirtual network to check
Returns
true if a network request is pending in the specified virtual network, false otherwise

◆ sendUntimedData()

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

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 14.0.

◆ setNotifyOnReceive()

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
functorFunctor to call when request is received

◆ setNotifyOnSend()

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
functorFunctor to call when request is sent

◆ spaceToSend()

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
vnVirtual network to check
num_bitsMinimum size in bits required to have space to send
Returns
true if there is space in the output, false otherwise
