Member Function Documentation

virtual void cMPICommunications::broadcast (  cCommBuffer *  buffer, int  tag )  [virtual]

Sends packed data with given tag to all partitions. Reimplemented from cParsimCommunications.

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

Creates an empty buffer of type cMPICommBuffer. Implements cParsimCommunications.

virtual cMPICommBuffer* cMPICommunications::doCreateCommBuffer (   )  [protected, virtual]

Factory method behind createCommBuffer(). Reimplemented in cPtrPassingMPICommunications.

virtual int cMPICommunications::getNumPartitions (   )  [virtual]

Returns total number of partitions. Implements cParsimCommunications.

virtual int cMPICommunications::getProcId (   )  [virtual]

Returns the MPI rank of this partition. Implements cParsimCommunications.

virtual void cMPICommunications::init (   )  [virtual]

Init the library. Implements cParsimCommunications.

virtual bool cMPICommunications::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 cMPICommunications::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 cMPICommunications::recycleCommBuffer (  cCommBuffer *  buffer  )  [virtual]

Recycle communication buffer after use. Implements cParsimCommunications.

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

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

virtual void cMPICommunications::shutdown (   )  [virtual]

Shutdown the communications library. Implements cParsimCommunications.
