simpeg.meta.MultiprocessingSumMetaSimulation

class simpeg.meta.MultiprocessingSumMetaSimulation(simulations, mappings, n_processes=None)

Bases: MultiprocessingMetaSimulation, SumMetaSimulation

A multiprocessing version of SumMetaSimulation.

See the documentation of MultiprocessingMetaSimulation for details on how to use multiprocessing for you operating system.

Parameters:

simulations(n_sim) list of simpeg.simulation.BaseSimulation

The list of unique simulations that each handle a piece of the problem.

mappings(n_sim) list of simpeg.maps.IdentityMap

The map for every simulation. Every map should accept the same length model, and output a model appropriate for its paired simulation.

n_processesoptional

The number of processes to spawn internally. This will default to multiprocessing.cpu_count(). The number of processes spawned will be the minimum of this number and the number of simulations.
