simpeg.meta.DaskRepeatedSimulation

class simpeg.meta.DaskRepeatedSimulation(simulation, mappings, client)

Bases: DaskMetaSimulation

A multiprocessing version of the RepeatedSimulation.

This class makes use of a single simulation that is copied to each internal process, but only once per process.

This simulation shares internals with the MultiprocessingMetaSimulation. class, as such please see that documentation for details regarding how to properly use multiprocessing on your operating system.

Parameters:

simulationsimpeg.simulation.BaseSimulation or dask.distributed.Future

The simulation to use repeatedly with different mappings.

mappings(n_sim) list of simpeg.maps.IdentityMap or list of dask.distributed.Future

The list of different mappings to use (or futures that each return a mapping).

clientdask.distributed.Client, optional

The dask client to use for communication.
