Detailed Description

Communication strategy for MPI-based distributed execution.

This strategy wraps a boost::mpi::communicator to provide distributed communication for running Benders decomposition across multiple MPI ranks. Subproblem solving is distributed across ranks rather than using local TBB parallelism.

Member Function Documentation

Barrier()

void MpiCommunicationStrategy::Barrier ( ) const

inlineoverridevirtual

Synchronization barrier across all processes (no-op for sequential)

Implements ICommunicationStrategy.

Rank()

int MpiCommunicationStrategy::Rank ( ) const

inlinenodiscardoverridevirtual

Return the rank of this process (0 for sequential)

Implements ICommunicationStrategy.

ShouldParallelize()

bool MpiCommunicationStrategy::ShouldParallelize ( ) const

inlinenodiscardoverridevirtual

Whether subproblems should be parallelized locally using TBB. Returns true for sequential (local parallelism), false for MPI (distribution handles parallelism across ranks).

Implements ICommunicationStrategy.

World()

mpi::communicator & MpiCommunicationStrategy::World ( )

inline

Access the underlying MPI communicator for operations not yet abstracted into the strategy interface (broadcast, gather, reduce).

WorldSize()

int MpiCommunicationStrategy::WorldSize ( ) const

inlinenodiscardoverridevirtual

Return the total number of processes (1 for sequential)

Implements ICommunicationStrategy.
