		const std::string &	statSubId = `""`
	)

inlineprotected

Registers a statistic.

If Statistic is allowed to run (controlled by Python runtime parameters), then a statistic will be created and returned. If not allowed to run, then a NullStatistic will be returned. In either case, the returned value should be used for all future Statistic calls. The type of Statistic and the Collection Rate is set by Python runtime parameters. If no type is defined, then an Accumulator Statistic will be provided by default. If rate set to 0 or not provided, then the statistic will output results only at end of sim (if output is enabled).

Parameters

References SST::TimeLord::getTimeConverter(), and SST::Simulation_impl::getTimeLord().

◆ requireLibrary()

void SST::BaseComponent::requireLibrary ( const std::string & name )

protected

Signifies that a library is required for this simulation.

Causes the Factory to verify that the required library is loaded.

NOTE: This function should rarely be required, as most dependencies are automatically detected in the simulator core. However, if the component uses an event from another library that is not wholly defined in a header file, this call may be required to ensure that all the code from the event is loaded. Similarly, if you use a class from another library that does not have ELI information, this call may also be required to make sure all dependencies are loaded.

Parameters

name	Name of library this BaseComponent depends on

References SST::Simulation_impl::requireLibrary().

◆ reregisterClock()

Cycle_t SST::BaseComponent::reregisterClock	(	TimeConverter *	freq,
		Clock::HandlerBase *	handler
	)

protected

Reactivates an existing Clock and Handler.

Returns: time of next time clock handler will fire

Note: If called after the simulation run loop (e.g., in finish() or complete()), will return the next time of the clock past when the simulation ended. There can be a small lag between simulation end and detection of simulation end during which clocks can run a few extra cycles. As a result, the return value just prior to simulation end may be greater than the value returned after simulation end.

References SST::Simulation_impl::reregisterClock().

◆ setup()

virtual void SST::BaseComponent::setup ( void )

inlinevirtual

Called after all components have been constructed and initialization has completed, but before simulation time has begun.

void SST::BaseComponent::sst_assert	(	bool	condition,
		uint32_t	line,
		const char *	file,
		const char *	func,
		int	exit_code,
		const char *	format,
			...
	)		const

protected

Convenience function for testing for and reporting fatal conditions.

If the condition holds, fatal() will be called, otherwise, the function will return. The function will create a new Output object and call fatal() using the supplied parameters. Before calling Output::fatal(), the function will also print other information about the (sub)component that called fatal and about the simulation state.

From Output::fatal: Message will be sent to the output location and to stderr. The output will be prepended with the expanded prefix set in the object. NOTE: fatal() will call MPI_Abort(exit_code) to terminate simulation.

Parameters

condition	on which to call fatal(); fatal() is called if the bool is false.
line	Line number of calling function (use CALL_INFO macro)
file	File name calling function (use CALL_INFO macro)
func	Function name calling function (use CALL_INFO macro)
exit_code	The exit code used for termination of simulation. will be passed to MPI_Abort()
format	Format string. All valid formats for printf are available.
...	Arguments for format.
