Bases: object

command: Union[str, idmtools.entities.command_line.CommandLine] = None

The Command to run

platform_requirements: Set[PlatformRequirements]

common_assets: AssetCollection

Common(Experiment-level) assets

transient_assets: AssetCollection

Transient(Simulation-level) assets

property metadata_fields

Collect all metadata fields

Returns: set of metadata filed names

add_pre_creation_hook(hook: Callable[[Union[Simulation, IWorkflowItem]], NoReturn])

Called before a simulation is created on a platform. Each hook receives either a Simulation or WorkflowTask

Parameters

hook – Function to call on event

Returns

None

add_post_creation_hook(hook: Callable[[Union[Simulation, IWorkflowItem]], NoReturn])

Called after a simulation has been created on a platform. Each hook receives either a Simulation or WorkflowTask

Parameters

hook – Function to call on event

Returns:

add_platform_requirement(requirement: Union[idmtools.entities.platform_requirements.PlatformRequirements, str]) → NoReturn

Adds a platform requirements to a task :param requirement: Requirement to add task

Returns

None

pre_creation(parent: Union[Simulation, IWorkflowItem])

Optional Hook called at the time of creation of task. Can be used to setup simulation and experiment level hooks :param parent:

Returns:

post_creation(parent: Union[Simulation, IWorkflowItem])

Optional Hook called at the after creation task. Can be used to setup simulation and experiment level hooks :param parent:

Returns:

abstract gather_common_assets() → idmtools.assets.asset_collection.AssetCollection

Function called at runtime to gather all assets in the collection.

abstract gather_transient_assets() → idmtools.assets.asset_collection.AssetCollection

Function called at runtime to gather all assets in the collection

gather_all_assets() → idmtools.assets.asset_collection.AssetCollection

Collect all common and transient assets

Returns: new AssetCollection

copy_simulation(base_simulation: Simulation) → Simulation

Called when copying a simulation for batching. Override you your task has specific concerns when copying

simulations.

reload_from_simulation(simulation: Simulation)

Optional hook that is called when loading simulations from a platform

to_simulation()

Convert task to simulation

Returns: new simulation

pre_getstate()

Return default values for pickle_ignore_fields(). Call before pickling.

Returns: dict

post_setstate()

property pickle_ignore_fields

to_dict() → Dict

Select metadata fields and make a new dict

Returns: dict
