Bamboostbamboostmpi
bamboost.mpi
This module handles the detection and selection of the appropriate MPI implementation for
Bamboost, either using mpi4py for real MPI environments or falling back to a mock MPI
implementation for non-MPI environments.
The detection logic considers user configuration options, environment variables, and the presence of common MPI-related environment variables.
If mpi4py is unavailable in an MPI environment, a fallback to the mock implementation is
also provided.
Usage
Instead of importing mpi4py.MPI directly, import MPI to use the
appropriate MPI module based on the current environment.
