class System

A simulated computer system

Inheritance:

Public Methods

System(const ID newID = 0, const string newName = "Simulated System")

Default constructor

~System()

Destructor

bool activate(void)

Activates the components of the simulator

bool simulate(void)

Starts the simulation

void extractTokenInfo(const Token& token, ID& tokenID, Thread*& thread, Process*& process, ID& computer, Computer*& computerPtr)

bool addComputer(Computer newComputer)

Adds a computer to the system

void replaceScheduler(Scheduler* newScheduler)

Replaces the system's scheduler with the one provided

bool connectComputers(const network_topology topology, const double bandwidth, const TIME latency, const TIME switchdelay)

Builds a network to connect the computers already in the system.

bool setProcessList(vector<Process*>* list)

Sets the systems process list to the one passed

void setMemAccessRate(const TIME rate)

Sets the default amount of time each process spends accessing virtual memory

void setCommRate(const TIME rate)

Sets the default amount of time each (parallel) process spends communicating.

void setSynchRate(const TIME rate)

void setMaxSimTime(const TIME time)

ID getNextComputer()

Returns the ID of the next computer able to accept more jobs

double getMemAccessRate(void) const

Gets the default percentage of time each parallel process spends accessing virtual memory.

double getCommRate(void) const

Gets the default percentage of time each (parallel) process spends communicating.

string toString(void) const

returns a string representation of the entire system

string toComputerString(void) const

string toProcessString(void) const

void calcMetrics(void)

Gathers interesting information from processes, resources, etc. and calculates metrics based on them.

void clearMetrics(void)

Resets metrics variables so that they may be recalculated

void calcAllocationMetrics(void)

string toMetricsString(void)

Converts the calculated metrics to a string suitable for printing to cout

string toMetricsLine(void)

Converts calculated metrics to a single-line string suitable for printing to a log file

void setUpdateOutput(OutputObject* out)

set the output object for simulator progress updates

void setMetricsOutput(OutputObject* out)

set the output object for simulator metrics updates

void setMetricsCollectionPeriod(TIME period)

Set the amount of time between metrics collections

Inherited from SimObj:

Public Methods

string getName(void) const

ID getID(void) const

void setName(const string newName)

void setID(const ID newID)

virtual void clear(void)

Documentation

The system class encapsulates all of the computers and their interconnecting network. It also stores all processes that will run on the system.

string toString(void) const

The representation will consist of every computer, every network component, and every process in the system. So look out - the output can be VERY large!

Returns:

a string representation of the system.

string toComputerString(void) const

Returns:

string info on computers in system

string toProcessString(void) const

Returns:

string info on processes in system

string toMetricsLine(void)

void setUpdateOutput(OutputObject* out)

void setMetricsOutput(OutputObject* out)

void setMetricsCollectionPeriod(TIME period)

This class has no child classes.
