void SchedulingSimulator::createInteractiveProcess ( double startTime )

creates a new interactive process event and adds it to the event scheduling queue

Parameters

startTime the time at which the process is created

Definition at line 148 of file schedulingSimulator.cpp.

std::shared_ptr< Process > SchedulingSimulator::createRealTimeTask	(	double	startTime,
		double	period,
		double	wcet,
		double	deadline = `0.0`,
		int	priority = `0`,
		double	bcet = `0.0`,
		double	powerCoeff = `1.0`
	)

creates a new real-time task event and add it to the event scheduling queue

Parameters

startTime	the time at which the first job spawns
period	the interval at which jobs are spawned
wcet	the amount of work a job has to do before the deadline. This is not a time, because the time to process it depends on the processor frequency.
deadline	the interval from the time where a job is spawned to the time it has to be completed. If this value is 0.0, the deadline is the period.
priority
isRandom	determines if the amount of work is random. In that case wcet is the worst-case amount of work
bcet	best case amount of work

Definition at line 132 of file schedulingSimulator.cpp.

void SchedulingSimulator::endSimulation ( double time )

set the end of the simulation

Parameters

time	the time at which to end simulation

Definition at line 160 of file schedulingSimulator.cpp.

void SchedulingSimulator::initializeTaskSet ( )

Builds the task set using a variety of methods This function is an alternative to using createRealTimeTask(), createInteractiveProcess(), or TaskSetGenerator::generate() and should be called before starting the simulation.

Definition at line 49 of file schedulingSimulator.cpp.

void SchedulingSimulator::seedRandomGenerator ( time_t seed )

seeds the random generator

Parameters

seed	The seed has a time_t type, so it can be seeded with the current time in order to have better randomness. But a constant number can also be used for repeatability

Definition at line 153 of file schedulingSimulator.cpp.

void SchedulingSimulator::setDummyEvent	(	double	start,
		double	interval
	)

Definition at line 196 of file schedulingSimulator.cpp.

void SchedulingSimulator::setFreqUpdate	(	double	start,
		double	interval
	)

Sets a timer at the end of which the frequency governor updates the frequency of processor.

Parameters

start	the time at which the first timer gets off
interval	the interval of time between two timeouts

Definition at line 181 of file schedulingSimulator.cpp.

void SchedulingSimulator::setSchedulerTimeout	(	double	start,
		double	interval
	)

sets the timeout at which the task scheduler is invoked

Parameters

start	the time at which the scheduler is invoked for the first time
interval	the interval at which the timer is invoked

Definition at line 188 of file schedulingSimulator.cpp.

void SchedulingSimulator::setStatsTick	(	double	start,
		double	interval
	)

Parameters

start	the time at which the first timeout occurs
interval	the interval at which the next timeouts appear

See also: StatsTick

Definition at line 174 of file schedulingSimulator.cpp.

void SchedulingSimulator::setUsageCalculationTimeout	(	double	start,
		double	interval
	)

Sets a UsageUpdate timeout.

Parameters

start	the time at which the first timeout occurs
interval	the interval at which the next timeouts will occur

See also: UsageUpdate

Definition at line 167 of file schedulingSimulator.cpp.

void SchedulingSimulator::startScheduler ( )

call this function to launch the simulation

Definition at line 204 of file schedulingSimulator.cpp.

void SchedulingSimulator::turnOnProcessor ( double start )

turns on the processor

Parameters

start the time at which to start the processor

Definition at line 235 of file schedulingSimulator.cpp.
