cFileCommunications Class Reference

#include <cfilecomm.h>

Description

Implementation of the communications layer which works via files. Every message is created as a file in a communications directory.

It is VERY slow, and only useful for understanding, debugging or demonstrating parallel simulation.

Member Function Documentation

init()

virtual void init ( int  numPartitions )

overridevirtual

Init the library.

Implements cParsimCommunications.

shutdown()

virtual void shutdown ( )

overridevirtual

Shutdown the communications library.

Implements cParsimCommunications.

getNumPartitions()

virtual int getNumPartitions ( ) const

overridevirtual

Returns total number of partitions.

Implements cParsimCommunications.

getProcId()

virtual int getProcId ( ) const

overridevirtual

Returns the id of this partition.

Implements cParsimCommunications.

createCommBuffer()

virtual cCommBuffer* createCommBuffer ( )

overridevirtual

Creates an empty buffer of type cFileCommBuffer.

Implements cParsimCommunications.

recycleCommBuffer()

virtual void recycleCommBuffer ( cCommBuffer *  buffer )

overridevirtual

Recycle communication buffer after use.

Implements cParsimCommunications.

send()

virtual void send ( cCommBuffer *  buffer, int  tag, int  destination  )

overridevirtual

Sends packed data with given tag to destination.

Implements cParsimCommunications.

receiveBlocking()

virtual bool receiveBlocking ( int  filtTag, cCommBuffer *  buffer, int &  receivedTag, int &  sourceProcId  )

overridevirtual

Receives packed data with given tag from given destination. Normally returns true; false is returned if blocking was interrupted by the user.

Implements cParsimCommunications.

receiveNonblocking()

virtual bool receiveNonblocking ( int  filtTag, cCommBuffer *  buffer, int &  receivedTag, int &  sourceProcId  )

overridevirtual

Receives packed data with given tag from given destination. Call is non-blocking – it returns true if something has been received, false otherwise.

Implements cParsimCommunications.
