class PNRServent

The PNRServent contains a PNR client, server, and manager. The servent controls the behavior of its components and stores data structures shared by each component.

Public Methods

PNRServent(Computer* _host = NULL, PNRStrategy _strategy = MANAGER)

~PNRServent()

void setPeers(map <ID, Computer>* computers)

Get a list of peers from the system and remember it for later.

void setMagicKnowledge(bool know = false)

Tell components whether they are allowed to use global knowledge or not

void setManagers(const unsigned int num = 0)

Set how many managers there will be in the current system

void setServerThreshold(const MEMAMT threshold = 0.1)

Sets the mimimum amount of RAM servers require to be idle before they start allocating network RAM.

ID getActiveServent(ID masterThreadHost, ID currentThreadHost, ID jobID = 0)

Returns the manager that will service the client's request.

bool broadcastingServent()

bool waitForOtherPeers()

PNRServer* getServer(void) const

PNRClient* getClient(void) const

PNRManager* getManager(void) const

PNRStrategy getStrategy(void) const

const list<ID> & getManagerList(void) const

Documentation

The PNRServent contains a PNR client, server, and manager. The servent controls the behavior of its components and stores data structures shared by each component.

PNRServent(Computer* _host = NULL, PNRStrategy _strategy = MANAGER)

~PNRServent()

void setPeers(map <ID, Computer>* computers)

void setMagicKnowledge(bool know = false)

void setManagers(const unsigned int num = 0)

This method should only be called when using the "backbone" PNR algorithm

void setServerThreshold(const MEMAMT threshold = 0.1)

ID getActiveServent(ID masterThreadHost, ID currentThreadHost, ID jobID = 0)

What manager is returned depends on which PNR algorithms are being used. For instance, if the centralized algorithm is being used, then the 0th manager is always returned.

bool broadcastingServent()

Returns:

whether the servent will broadcast load information after job start/stop

bool waitForOtherPeers()

Returns:

whether the servent waits for other servents when performing operations (such as network RAM allocation).

PNRServer* getServer(void) const

Returns:

a pointer to the servent's server.

PNRClient* getClient(void) const

Returns:

a pointer to the servent's client

PNRManager* getManager(void) const

Returns:

a pointer to the servent's manager

PNRStrategy getStrategy(void) const

Returns:

an enumerated type that represents what PNR algorithm is being used.

const list<ID> & getManagerList(void) const

Returns:

the list of managers currently in the system.

This class has no child classes.
