Detailed Description

This class implements a wrapper to a Trilinos Epetra_Import object, for use in places where a Utilities::MPI::CommunicationPatternBase object is required.

Definition at line 40 of file trilinos_epetra_communication_pattern.h.

Constructor & Destructor Documentation

◆ CommunicationPattern()

LinearAlgebra::EpetraWrappers::CommunicationPattern::CommunicationPattern ( const IndexSet & locally_owned_indices,
const IndexSet & ghost_indices,
const MPI_Comm communicator )

Initialize the communication pattern.

Parameters
[in]locally_owned_indicesThe set of indices of elements in the array mentioned in the class documentation that are stored on the current process.
[in]ghost_indicesThe 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]communicatorThe MPI communicator used to describe the entire set of processes that participate in the storage and access to elements of the array.

Definition at line 31 of file trilinos_epetra_communication_pattern.cc.

Member Function Documentation

◆ reinit()

void LinearAlgebra::EpetraWrappers::CommunicationPattern::reinit ( const IndexSet & locally_owned_indices,
const IndexSet & ghost_indices,
const MPI_Comm communicator )
overridevirtual

Reinitialize the communication pattern.

Parameters
[in]locally_owned_indicesThe set of indices of elements in the array mentioned in the class documentation that are stored on the current process.
[in]ghost_indicesThe 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]communicatorThe MPI communicator used to describe the entire set of processes that participate in the storage and access to elements of the array.

Implements Utilities::MPI::CommunicationPatternBase.
