Integrators

cubie.integrators

The SingleIntegratorRun interface is the primary entry point. It creates a loop callable by combining controller, algorithm, and loop submodules as directed by the supplied IntegratorRunSettings.

The cubie.integrators package coordinates CUDA-based initial value problem integrations. It bundles algorithm factories, controller builders, matrix-free solver helpers, and loop orchestrators that combine CUDA device functions from ODE systems with adaptive or fixed step control.

Subpackages

• Algorithms
• Loops
• Matrix-free solvers
• Step control

Core API

• SingleIntegratorRun – high-level integration driver.

• IntegratorReturnCodes – enumerates loop exit statuses.

Dependencies

• Implicit algorithms obtain Newton–Krylov helpers from cubie.integrators.matrix_free_solvers via get_solver_helper_fn closures.

• Loop factories depend on cubie.outputhandling for compile flags and saving callbacks generated by cubie.outputhandling.output_functions.OutputFunctions.

• Controllers operate alongside algorithm step objects exposed by cubie.integrators.algorithms to manage adaptive step sizes.
