Detailed Description

Benchmark instance which can do a single run.

The run is controlled by the event population size and total number of events, which are set at construction.

The event distribution in time is set by SetRandomStream()

Constructor & Destructor Documentation

Bench()

Bench::Bench ( const uint64_t  population, const uint64_t  total  )

inline

Constructor.

Parameters

[in]	population	The number of events to keep in the scheduler.
[in]	total	The total number of events to execute.

Cb()

void Bench::Cb ( )

private

Event function.

This checks for completion (total number of events executed) and schedules a new event if not complete.

SetPopulation()

void Bench::SetPopulation ( const uint64_t  population )

inline

Set the number of events to populate the scheduler with.

Each event executed schedules a new event, maintaining the population.

Parameters

[in]

population

The number of events to keep in the scheduler.

SetRandomStream()

void Bench::SetRandomStream ( Ptr< RandomVariableStream >  stream )

inline

Set the event delay interval random stream.

Parameters

[in]

stream

The random variable stream to be used to generate delays for future events.
