class Scheduler

Schedules the jobs that run on the system.

Inheritance:

Public Methods
Scheduler(): Default constructor
virtual ~Scheduler(): Destructor
virtual void setComputers(map<ID, Computer>* newComputers): Gives the scheduler relevant information about computers in the system
void setNetwork(Network* newNetwork): Gives the scheuduler relevant information about the network
void setQueuedEvents(QueuedEvents* newEvents): Gives the scheduler access to events queued for execution in the system
void setProcessList(map <ID, Process*>* newList): Gives the scheduler access to process information
void setPacking(const Packing newPacking): Sets the scheduler's packing scheme
void setPriority(const Priority newPriority): Sets the scheduler's waiting queue priority scheme
void setSchedulingOverhead(const TIME overhead): Sets the amount of simulation time the scheduler spends thinking about what to do
virtual void setMemoryAware(const bool value): Sets whether the scheduler will be aware of memory constraints or not.
virtual Policy getPolicy() const: Get the scheduling policy
bool getMemoryAware() const
virtual bool submitProcess(const Token& token): Takes appropriate actions when the given job is submitted into the system
virtual bool startProcess(const Token& token): Takes appropriate actions when the given job starts on the system
virtual bool terminateProcess(const Token& token): Takes appropriate actions when the given job has terminated.
virtual bool timeQuantumExpired(): Takes appropriate actions when the time quantum alloted to the jobs currently in the system has expired.
virtual bool schedule(bool start = true): Decides what processes should be run, and when
virtual bool isCurrentlyRunning(Process* process)

Scheduler()

virtual ~Scheduler()

virtual void setComputers(map<ID, Computer>* newComputers)

void setNetwork(Network* newNetwork)

void setQueuedEvents(QueuedEvents* newEvents)

void setProcessList(map <ID, Process*>* newList)

void setPacking(const Packing newPacking)

void setPriority(const Priority newPriority)

void setSchedulingOverhead(const TIME overhead)

virtual void setMemoryAware(const bool value)

If the scheduler is aware of memory constraints, it may choose to queue jobs that would otherwise run (that is, they'd have enough processors to run)

virtual Policy getPolicy() const

Examples include space-sharing, backfilling, and gang scheduling

bool getMemoryAware() const


Returns:: true if the scheduler is memory aware (cares about whether paging will be invoked or not). False otherwise.
