Detailed 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

virtual cCommBuffer* cFileCommunications::createCommBuffer (   )  [virtual]

Creates an empty buffer of type cFileCommBuffer. Implements cParsimCommunications.

virtual int cFileCommunications::getNumPartitions (   )  [virtual]

Returns total number of partitions. Implements cParsimCommunications.

virtual int cFileCommunications::getProcId (   )  [virtual]

Returns the id of this partition. Implements cParsimCommunications.

virtual void cFileCommunications::init (   )  [virtual]

Init the library. Implements cParsimCommunications.

virtual bool cFileCommunications::receiveBlocking (  int  filtTag, cCommBuffer *  buffer, int &  receivedTag, int &  sourceProcId )  [virtual]

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

virtual bool cFileCommunications::receiveNonblocking (  int  filtTag, cCommBuffer *  buffer, int &  receivedTag, int &  sourceProcId )  [virtual]

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.

virtual void cFileCommunications::recycleCommBuffer (  cCommBuffer *  buffer  )  [virtual]

Recycle communication buffer after use. Implements cParsimCommunications.

virtual void cFileCommunications::send (  cCommBuffer *  buffer, int  tag, int  destination )  [virtual]

Sends packed data with given tag to destination. Implements cParsimCommunications.

virtual void cFileCommunications::shutdown (   )  [virtual]

Shutdown the communications library. Implements cParsimCommunications.
