polaris.tasks.ocean.realistic_global.restart.validate.Validate

class polaris.tasks.ocean.realistic_global.restart.validate.Validate(component, full_run_subdir, restart_subdir, indir)

Check that a run split across a restart writes the same history as the same run done in one go.

Two things are checked, because a restart can go wrong in two ways. The time axis has to hold every frame of the whole period, in increasing order: Omega #482 was a case where the continuing segment silently overwrote the earlier frames instead of appending to them, leaving a file that was well formed and simply missing its first half. The state then has to match the uninterrupted run, which is the usual exact-restart check.

Variables:

• full_run_subdir (str) – Subdirectory of the step that ran the whole period in one go

• restart_subdir (str) – Subdirectory of the final segment of the restart chain

__init__(component, full_run_subdir, restart_subdir, indir)

Create the step

Parameters:

• component (polaris.Component) – The component the step belongs to

• full_run_subdir (str) – Subdirectory of the step that ran the whole period in one go

• restart_subdir (str) – Subdirectory of the final segment of the restart chain

• indir (str) – the directory the step is in, to which name will be appended

Methods

__init__(component, full_run_subdir, ...)	Create the step
add_dependency(step[, name])	Add step as a dependency of this step (i.e. this step can't run until the dependency has finished).
add_horiz_mesh_input_file(**kwargs)	Add the horizontal-mesh input file using a placeholder that is resolved to the configured filename at process_inputs_and_outputs() time.
add_init_input_file(**kwargs)	Add the initial-condition input file using a placeholder that is resolved to the configured filename at process_inputs_and_outputs() time.
add_input_file([filename, target, database, ...])	Add an input file to the step (but not necessarily to the MPAS model).
add_output_file(filename[, validate_vars, ...])	Add an output file, optionally resolving validate_class to a pre-defined list of variables from the Ocean component.
add_output_files_for_ocean_model_input([...])	Register output files that will be consumed by the ocean model as inputs (horizontal mesh, initial condition, and model-specific files).
add_produced_file(filename)	Register a file the step has just written as one of its outputs
add_property_check(filename, check_properties)	Add a single conservation comparison for an output file
add_vert_coord_input_file([filename])	Add the vertical-coordinate input file.
check_properties()	Check conservation properties of the output files of this step.
constrain_resources(available_resources)	Constrain cpus_per_task and ntasks based on the number of cores available to this step
get_horiz_mesh_filename()	Get the configured local filename for the horizontal mesh file.
get_init_filename()	Get the configured local filename for the initial-condition file.
get_vert_coord_filename()	Get the configured local filename for the vertical coordinate file.
map_from_native_model_vars(ds)	If the model is Omega, rename dimensions and variables in a dataset from their Omega names to the MPAS-Ocean equivalent (appropriate for datasets that are output from the model)
map_to_native_model_vars(ds)	If the model is Omega, rename dimensions and variables in a dataset from their MPAS-Ocean names to the Omega equivalent (appropriate for input datasets like an initial condition)
open_model_dataset(filename[, config, ...])	Open the given dataset, mapping variable and dimension names from Omega to MPAS-Ocean names if appropriate
open_vert_coord_dataset(ds_init[, ...])	Return the dataset containing vertical-coordinate variables (bottomDepth, minLevelCell, maxLevelCell, vertCoordMovementWeights and either restingThickness or RefPseudoThickness).
process_inputs_and_outputs()	Resolve <<<placeholder>>> filenames to configured names and drop <<<vert_coord>>> entries for MPAS-Ocean before delegating to the base Step processing.
run()	Compare the history of the restart chain with the history of the uninterrupted run
runtime_setup()	Update attributes of the step at runtime before calling the run() method.
set_resources([cpus_per_task, ...])	Update the resources for the subtask.
set_shared_config(config[, link])	Replace the step's config parser with the shared config parser
setup()	Set up the task in the work directory, including downloading any dependencies.
validate_baselines()	Compare variables between output files in this step and in the same step from a baseline run if one was provided.
work_path(*filenames)	Get the absolute path to a file or directory in the step's work directory
write_horiz_mesh_dataset(ds, filename, config)	Write a horizontal mesh dataset, validating that all expected mesh variables are present before writing.
write_initial_state_dataset(ds, filename, config)	Write an initial-state dataset, converting the tracers to the convention the model expects and omitting horizontal mesh fields and (for Omega) vertical coordinate fields.
write_model_dataset(ds, filename, config)	Write out the given dataset, mapping dimension and variable names from MPAS-Ocean to Omega names if appropriate
write_vert_coord_dataset(ds, filename, config)	Write a vertical-coordinate dataset for Omega's InitialVertCoord stream.
