Class ConstantScheduler

java.lang.Object
  |
  +--physis.core.scheduler.ConstantScheduler

All Implemented Interfaces:

Scheduler

public class ConstantScheduler

extends java.lang.Object

implements Scheduler

This is the simplest scheduling algorithm. All organisms get the same number of cpu cycles. (This encourages code-shrinking.) (this scheduling was used only in early development phase)

Field Summary

(package private) DigitalOrganismIterator

orgs

Constructor Summary

ConstantScheduler()

Method Summary

void	fillWithOrganisms(DigitalOrganismIterator orgs_) Before starting the scheduling process the scheduler has to build up its internal data structure.
void	scheduleUpdate(int average) It schedules the executing of each digital organisms.

public ConstantScheduler()

Method Detail

scheduleUpdate

public void scheduleUpdate(int average)

Description copied from interface: Scheduler

It schedules the executing of each digital organisms. The problem: we have to emulate the parallel processing of the virtual processors, and we have to take care the different working speeds.

Specified by:

scheduleUpdate in interface Scheduler

Following copied from interface: physis.core.scheduler.Scheduler

Parameters:

average_time_slice - the average number of executed instructions/per unit.

fillWithOrganisms

public void fillWithOrganisms(DigitalOrganismIterator orgs_)

Description copied from interface: Scheduler

Before starting the scheduling process the scheduler has to build up its internal data structure. The parameter is an iterator of the whole population.

Specified by:

fillWithOrganisms in interface Scheduler
