polaris.ocean.tasks.cosine_bell.decomp.Decomp

class polaris.ocean.tasks.cosine_bell.decomp.Decomp(component, config, icosahedral, refinement_factor, refinement, proc_counts)[source]

A cosine bell decomposition task, which makes sure the model produces identical results on different numbers of cores.

__init__(component, config, icosahedral, refinement_factor, refinement, proc_counts)[source]

Create the convergence test

Parameters:

  • component (polaris.ocean.Ocean) – The ocean component that this task belongs to

  • config (polaris.config.PolarisConfigParser) – A shared config parser

  • icosahedral (bool) – Whether to use icosahedral, as opposed to less regular, JIGSAW meshes

  • refinement_factor (float) – The factor by which to scale space, time or both

  • refinement (str) – Refinement type. One of ‘space’, ‘time’ or ‘both’ indicating both space and time

  • proc_counts (list of int) – The number of processors to run each step on

Methods

__init__(component, config, icosahedral, ...)

Create the convergence test

add_step([step, subdir, symlink, run_by_default])

Add a step to the task and component (if not already present)

configure()

Modify the configuration options for this task.

remove_step(step)

Remove the given step from this task and the component

set_shared_config(config[, link])

Replace the task's config parser with the shared config parser
