Uses of Topologies
- Knowledge of application topology can be used to efficiently assign
processes to processors.
- Cartesian grids can be divided into hyperplanes by removing specified
dimensions.
- MPI provides support for shifting data along a specified dimension of
a Cartesian grid.
- MPI provides support for performing collective communication
operations along a specified grid direction.
