Detailed Description

Interface of a specific MPI communicator for synchronizations.

This communicator allows the use of MPI 3.1 methods such as MPI_Neighbor_alltoallv() for synchronizations.

compute() must be called before this communicator can be used specifically.

Member Function Documentation

communicator()

virtual MPI_Comm Arcane::IVariableSynchronizerMpiCommunicator::communicator ( ) const

pure virtual

Retrieves the specific communicator from the topology.

This communicator should not be retained because it may be invalidated between two calls to compute().

Implemented in Arcane::VariableSynchronizerMpiCommunicator.

compute()

virtual void Arcane::IVariableSynchronizerMpiCommunicator::compute ( VariableSynchronizer * var_syncer )

pure virtual

Calculates the specific communicator.

Implemented in Arcane::VariableSynchronizerMpiCommunicator.
