Detailed Description

Main component object for the simulation.

All models inherit from this.

Member Function Documentation

void SST::Component::primaryComponentDoNotEndSim ( )

Tells the simulation that it should not exit.

The component will remain in this state until a call to primaryComponentOKToEndSim().

See Also
Component::registerAsPrimaryComponent()
Component::primaryComponentOKToEndSim()
void SST::Component::primaryComponentOKToEndSim ( )

Tells the simulation that it is now OK to end simulation.

Simulation will not end until all primary components have called this function.

See Also
Component::registerAsPrimaryComponent()
Component::primaryComponentDoNotEndSim()
void SST::Component::registerAsPrimaryComponent ( )

Register as a primary component, which allows the component to specify when it is and is not OK to end simulation.

The simulator will not end simulation naturally (through use of the Exit object) while any primary component has specified primaryComponentDoNotEndSim(). However, it is still possible for Actions other than Exit to end simulation. Once all primary components have specified primaryComponentOKToEndSim(), the Exit object will trigger and end simulation.

This must be called during simulation wireup (i.e during the constructor for the component). By default, the state of the primary component is set to OKToEndSim.

If no component registers as a primary component, then the Exit object will not be used for that simulation and simulation termination must be accomplished through some other mechanism (e.g. –stopAt flag, or some other Action object).

See Also
Component::primaryComponentDoNotEndSim()
Component::primaryComponentOKToEndSim()
bool SST::Component::registerExit ( )

Register that the simulation should not end until this component says it is OK to.

Calling this function (generally done in Component::setup() or in component constructor) increments a global counter. Calls to Component::unregisterExit() decrements the counter. The simulation cannot end unless this counter reaches zero, or the simulation time limit is reached. This counter is synchronized periodically with the other nodes.

Component::unregisterExit()
SST::Component::SST_ELI_DECLARE_INFO_EXTERN ( ELI::ProvidesParams  ,
ELI::ProvidesSubComponentSlots  ,
ELI::ProvidesPorts  ,
ELI::ProvidesStats  ,
ELI::ProvidesCategory   
)

Constructor.

Generally only called by the factory class.

Parameters
idUnique component ID
bool SST::Component::unregisterExit ( )

Indicate permission for the simulation to end.

This function is the mirror of Component::registerExit(). It decrements the global counter, which, upon reaching zero, indicates that the simulation can terminate.

See Also
Component::registerExit()
