A step for setting up a single ensemble member

Variables:

• run_num (integer) – the run number for this ensemble member

• name (str) – the name of the run being set up in this step

• ntasks (integer) – the number of parallel (MPI) tasks the step would ideally use

• input_file_name (str) – name of the input file that was read from the config

• basal_fric_exp (float) – value of basal friction exponent to use

• mu_scale (float) – value to scale muFriction by

• stiff_scale (float) – value to scale stiffnessFactor by

• von_mises_threshold (float) – value of von Mises stress threshold to use

• calv_spd_lim (float) – value of calving speed limit to use

• gamma0 (float) – value of gamma0 to use in ISMIP6 ice-shelf basal melt param.

• deltaT (float) – value of deltaT to use in ISMIP6 ice-shelf basal melt param.

__init__(test_case, run_num, basal_fric_exp=None, mu_scale=None, stiff_scale=None, von_mises_threshold=None, calv_spd_lim=None, gamma0=None, meltflux=None, deltaT=None)

Creates a new run within an ensemble

Parameters:

• test_case (compass.TestCase) – The test case this step belongs to

• mu_scale (float) – value to scale muFriction by

• stiff_scale (float) – value to scale stiffnessFactor by

• von_mises_threshold (float) – value of von Mises stress threshold to use assumes same value for grounded and floating ice

• calv_spd_lim (float) – value of calving speed limit to use

• gamma0 (float) – value of gamma0 to use in ISMIP6 ice-shelf basal melt param.

• deltaT (float) – value of deltaT to use in ISMIP6 ice-shelf basal melt param.

Methods

__init__(test_case, run_num[, ...])	Creates a new run within an ensemble
add_input_file([filename, target, database, ...])	Add an input file to the step (but not necessarily to the MPAS model).
add_model_as_input()	make a link to the model executable and add it to the inputs
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_namelist_options(options[, out_name, mode])	Add the namelist replacements to be parsed when generating a namelist file if and when the step gets set up.
add_output_file(filename)	Add the output file that must be produced by this step and may be made available as an input to steps, perhaps in other test cases.
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.
constrain_resources(available_resources)	Constrain cpus_per_task and ntasks based on the number of cores available to this step
process_inputs_and_outputs()	Process the inputs to and outputs from a step added with compass.Step.add_input_file() and compass.Step.add_output_file().
run()	Run this member of the ensemble.
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.
setup()	Set up this run by setting up a baseline run configuration and then modifying parameters for this ensemble member based on an externally provided unit parameter vector
update_namelist_at_runtime(options[, out_name])	Update an existing namelist file with additional options.
update_namelist_pio([out_name])	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).
update_streams_at_runtime(package, streams, ...)	Update the streams files during the run phase of this step using the given template and replacements.
