Bases: ElementSet

Class to represent a parameterisation of a new set of elements.

Parameters:
  • inputs (list[InputValue]) – Inputs to the set of elements.

  • input_files (list[InputFile]) – Input files to the set of elements.

  • sequences (list[ValueSequence]) – Input value sequences to parameterise over.

  • resources (ResourceList) – Resources to use for the set of elements.

  • repeats (list[dict]) – Description of how to repeat the set of elements.

  • groups (list[ElementGroup]) – Groupings in the set of elements.

  • input_sources (dict[str, InputSource]) – Input source descriptors.

  • nesting_order (dict[str, int]) – How to handle nesting of iterations.

  • env_preset (str) – Which environment preset to use. Don’t use at same time as environments.

  • environments (dict) – Environment descriptors to use. Don’t use at same time as env_preset.

  • sourceable_elem_iters (list[int]) – If specified, a list of global element iteration indices from which inputs for the new elements associated with this element set may be sourced. If not specified, all workflow element iterations are considered sourceable.

  • allow_non_coincident_task_sources (bool) – If True, if more than one parameter is sourced from the same task, then allow these sources to come from distinct element sub-sets. If False (default), only the intersection of element sub-sets for all parameters are included.

  • merge_envs (bool) – If True, merge environments into resources using the “any” scope. If False, environments are ignored. This is required on first initialisation, but not on subsequent re-initialisation from a persistent workflow.
