Member Function Documentation

setProcessCommunicatorToRecvArry()

int oofem::ElementCommunicator::setProcessCommunicatorToRecvArry ( ProcessCommunicator * processComm, IntArray & map )

overridevirtual

Assigns given map to given process communicator. Sorts map according to global entity (dofmanagers or element) numbers to ensure, that local and corresponding remote process have the identical map with same ordering. This will ensure proper packing/unpacking order. The corresponding processCommunicator buffer takes care about resizing itself accordingly to hold all outgoing/incoming data using engngModel->estimateMaxPackSize service.

Parameters

processComm	Process comm which received map will be set.
map	Received map.

Implements oofem::ProblemCommunicator.

setProcessCommunicatorToSendArry()

int oofem::ElementCommunicator::setProcessCommunicatorToSendArry ( ProcessCommunicator * processComm, IntArray & map )

overridevirtual

Assigns given map to given process communicator. Sorts map according to global entity (dofmanagers or element) numbers to ensure, that local and corresponding remote process have the identical map with same ordering. This will ensure proper packing/unpacking order. The corresponding processCommunicator buffer takes care about resizing itself accordingly to hold all outgoing/incoming data using engngModel->estimateMaxPackSize service.

Parameters

processComm	Domain comm which send map will be set.
map	Send map.

setUpCommunicationMaps()

void oofem::ElementCommunicator::setUpCommunicationMaps ( EngngModel * emodel, bool excludeSelfCommFlag, bool forceReinit = false )

overridevirtual

Service for setting up the communication patterns with other remote process. Sets up the toSend and toRecv attributes in associated process communicators.

Parameters

emodel	Associated engineering model.
excludeSelfCommFlag	If set to true, the communication map of receiver with itself will be forced to be empty, otherwise it will be assembled.
forceReinit	Forces reinitilaization.
