The MPI engine for foxes calculations.

Examples¶

Run command, e.g. for 12 processors and a script run.py:

>>> mpiexec -n 12 -m mpi4py.futures run.py

Public members¶

map(func, inputs, *args, **kwargs)[source]

Runs a function on a list of files

run_calculation(algo, model, model_data=None, farm_data=None, ...)[source]

Runs the model calculation

MPIEngine(chunk_size_states=None, chunk_size_points=None, ...)[source]

Constructor.

__repr__()[source]

Return repr(self).

property entered

Flag that this model has been entered.

property initialized

Initialization flag.

initialize()[source]

Initializes the engine.

finalize(type=None, value=None, traceback=None)[source]

Finalizes the engine.

print(*args, level=1, **kwargs)[source]

Prints based on verbosity

property loop_dims
