Detailed Description

Base class defining basic scheduler functionality.

This requires keeping a heap of LPs ordered by next event, methods for updating this heap, the ability to execute events on these LPs, and basic statistics and global variable management.

Member Function Documentation

◆ execute()

void Scheduler::execute ( )

virtual

Entry method for executing a scheduler iteration.

Needs to be overridden by each base class to define a scheduler iteration.

◆ get_min_time()

Time Scheduler::get_min_time ( ) const

virtual

Get the minimum time of any event on this PE.

Return the time of the minimum unexecuted event on this PE.

◆ schedule_next_lp()

bool Scheduler::schedule_next_lp ( )

Calls execute_me() on the next LP in the queue.

Attempt to execute the next LPs next event, returning false if it fails.

◆ start_simulation()

void Scheduler::start_simulation ( )

Methods for starting and stopping the entire simulation.

Sets initial state and calls execute()
