Simulation.Aivika.Experiment.Types

Description

Tested with: GHC 8.0.1

The module defines the simulation experiments. They automate the process of generating and analyzing the results. Moreover, this module is open to extensions, allowing you to define your own output views for the simulation results, for example, such views that would allow saving the results in PDF or as charts. To decrease the number of dependencies, such possible extenstions are not included in this package, although simple views are provided.

runExperiment Source #

Arguments

:: (ExperimentRendering r, Monad (ExperimentMonad r), MonadIO (ExperimentMonad r), MonadException (ExperimentMonad r))
=> Experiment	the simulation experiment to run
-> [ExperimentGenerator r]	generators used for rendering
-> r	the rendering backend
-> Simulation Results	the simulation results received from the model
-> IO (Either SomeException ())

Run the simulation experiment sequentially. For example, it can be a Monte-Carlo simulation dependentent on the external Parameter values.

runExperimentParallel Source #

Arguments

:: (ExperimentRendering r, Monad (ExperimentMonad r), MonadIO (ExperimentMonad r), MonadException (ExperimentMonad r))
=> Experiment	the simulation experiment to run
-> [ExperimentGenerator r]	generators used for rendering
-> r	the rendering backend
-> Simulation Results	the simulation results received from the model
-> IO (Either SomeException ())

Run the simulation experiment in parallel.

Make sure that you compile with -threaded and supply +RTS -N2 -RTS to the generated Haskell executable on dual core processor, or you won't get any parallelism. Generally, the mentioned N parameter should correspond to the number of cores for your processor.

In case of need you might want to specify the number of threads directly with help of experimentNumCapabilities, although the real number of parallel threads can depend on many factors.

runExperimentWithExecutor Source #

Arguments

:: (ExperimentRendering r, Monad (ExperimentMonad r), MonadIO (ExperimentMonad r), MonadException (ExperimentMonad r))
=> ([IO ()] -> IO a)	an executor that allows parallelizing the simulation if required
-> Experiment	the simulation experiment to run
-> [ExperimentGenerator r]	generators used for rendering
-> r	the rendering backend
-> Simulation Results	the simulation results received from the model
-> IO (Either SomeException a)

Run the simulation experiment with the specified executor.
