class PNRAgent

Generic PNR peer - other peers inherit from this class.

Inheritance:

Public Methods

PNRAgent(Computer* _host = NULL)

~PNRAgent()

void setHost(Computer* _host = NULL)

Set the host the peer currently resides on

void setGrantingThreshold(const MEMAMT _newThreshold = 0.1)

Set the RAM threshold PNR servers will be using

Computer* getHost(void) const

void setAvailabilityTable(map<Computer*, MEMAMT>* table)

Set a reference to the availability table of the servent

void setComputerTable(map<ID, Computer>* table)

Set a reference to the computer table of the servent

void loadMagicKnowledge()

Loads current information about each computer into the availability table

void setMagicKnowledge()

Sets whether magic knowledge will be used or not.

Computer* selectServer()

Select a networkRAM server from a list of available servers

bool serverAvailable()

Indicates if a remote server has network RAM available for a manager's allocation

Documentation

An object that all PNR servers, managers, and clients inherit from Provides data structures and services that are common across all the types of peers.

PNRAgent(Computer* _host = NULL)

~PNRAgent()

void setHost(Computer* _host = NULL)

void setGrantingThreshold(const MEMAMT _newThreshold = 0.1)

The RAM threshold indicates how much RAM must be idle before a server will grant network RAM to a remote client.

Computer* getHost(void) const

Returns:

the host the peer currently resides on

void setAvailabilityTable(map<Computer*, MEMAMT>* table)

The availability table is used to select servers, etc. One availability table is stored in the PNR servent - and many agents (clients/managers/servers) may access it.

void setComputerTable(map<ID, Computer>* table)

void loadMagicKnowledge()

This method is invoked when peers are using "magic" knowledge. That is, peers are allowed to instantly know global information about the system

void setMagicKnowledge()

Computer* selectServer()

The selection process is based on the manager's information on how much network RAM various servers have available. This information may be out-of-date since it is updated via message passing.
