Member Function Documentation

getCommDims()

unsigned int NeighbourCommunicationScheme::getCommDims ( )

inline

Specifies the amount of sequential communication steps needed for the communication scheme. This is also the outer size of DomainDecompMPIBase::_neighbours

Returns

Member Data Documentation

_coversWholeDomain

bool NeighbourCommunicationScheme::_coversWholeDomain[3]

protected

flag, which tells whether a processor covers the whole domain along a dimension if true, we will use the methods provided by the base class for handling the respective dimension, instead of packing and unpacking messages to self
