polaris.tasks.seaice.single_column.forward.Forward

class polaris.tasks.seaice.single_column.forward.Forward(component, name='forward', indir=None)

A step for staging a mesh for “single column” test cases

__init__(component, name='forward', indir=None)

Create the step

Parameters:

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

• name (str, optional) – The name of the step

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

Methods

__init__(component[, name, indir])	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_input_file([filename, target, database, ...])	Add an input file to the step (but not necessarily to the MPAS model).
add_model_config_options(options[, config_model])	Add the replacement model config options to be parsed when generating a namelist or yaml file if and when the step gets set up.
add_namelist_file(package, namelist)	Add a file with updates to namelist options to the step to be parsed when generating a complete namelist file if and when the step gets set up.
add_output_file(filename[, validate_vars])	Add the output file that must be produced by this step and may be made available as an input to steps, perhaps in other tasks.
add_streams_file(package, streams[, ...])	Add a streams file to the step to be parsed when generating a complete streams file if and when the step gets set up.
add_yaml_file(package, yaml[, ...])	Add a file with updates to yaml config options to the step to be parsed when generating a complete yaml file if and when the step gets set up.
constrain_resources(available_resources)	Constrain cpus_per_task and ntasks based on the number of cores available to this step
dynamic_model_config(at_setup)	Add model config options, namelist, streams and yaml files using config options or template replacements that need to be set both during step setup and at runtime
map_yaml_configs(configs, config_model)	A mapping between model config options from different models.
map_yaml_options(options, config_model)	A mapping between model config options from different models.
map_yaml_streams(streams, config_model)	A mapping between model streams from different models.
map_yaml_to_namelist(options)	A mapping from yaml model config options to namelist options.
partition([graph_file])	Partition the domain for the requested number of tasks
process_inputs_and_outputs()	Process the model as an input, then call the parent class' version
run()	Run the step.
runtime_setup()	Update PIO namelist options, make graph file, and partition graph file (if any of these are requested)
set_model_resources([ntasks, min_tasks, ...])	Update the resources for the step.
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()	Setup the command-line arguments
update_namelist_pio()	Modify the namelist so the number of PIO tasks and the stride between them consistent with the number of nodes and cores (one PIO task per node).
validate_baselines()	Compare variables between output files in this step and in the same step from a baseline run if one was provided.
