Bases: ElementActionRun

The Element Action Run (EAR) is an atomic unit of an enacted workflow, representing one unit of work (e.g., particular submitted job to run a program) within that overall workflow. With looping over, say, parameter spaces, there may be many EARs per element.

Parameters:

id (int) – The ID of the EAR.
is_pending (bool) – Whether this EAR is pending.
element_action (ElementAction) – The particular element action that this is a run of.
index (int:) – The index of the run within the collection of runs.
data_idx (dict) – Used for looking up input data to the EAR.
commands_idx (list[int]) – Indices of commands to apply.
start_time (datetime) – Time of start of run, if the run has ever been started.
end_time (datetime) – Time of end of run, if the run has ever ended.
snapshot_start (dict) – Parameters for taking a snapshot of the data directory before the run. If unspecified, no snapshot will be taken.
snapshot_end (dict) – Parameters for taking a snapshot of the data directory after the run. If unspecified, no snapshot will be taken.
submission_idx (int) – What submission was this (if it has been submitted)?
success (bool) – Whether this EAR succeeded (if it has run).
skip (bool) – Whether this EAR was skipped.
exit_code (int) – The exit code, if known.
metadata (dict) – Metadata about the EAR.
run_hostname (str) – Where to run the EAR (if not locally).
id_ (int) –
