Constructor & Destructor Documentation

◆ CommunicationPattern()

template<typename MemorySpace >

LinearAlgebra::TpetraWrappers::CommunicationPattern< MemorySpace >::CommunicationPattern	(	const IndexSet &	locally_owned_indices,
		const IndexSet &	ghost_indices,
		const MPI_Comm	communicator )

Initialize the communication pattern.

Parameters

[in]	locally_owned_indices	The set of indices of elements in the array mentioned in the class documentation that are stored on the current process.
[in]	ghost_indices	The set of indices of elements in the array mentioned in the class documentation that the current process will need to be able to import.
[in]	communicator	The MPI communicator used to describe the entire set of processes that participate in the storage and access to elements of the array.
