Map task

Copy subgraph

Should not deepcopy:

• input value (especially the AiiDA node)

Should update: - input value from the map - children - parent - input_links

Set context

For mapped tasks, should use dict to hold the results

Collect results

Inside while zone

If the while zone reset, how to handle the copied subgraph, delete or re-use? Note, the node in the subgraph may have been modified by the while zone, so the subgraph may not be the same as the original one.

Edge Cases

• Empty subgraph under a MAP node (no children). Just mark the node FINISHED.

• Empty source (no items). Possibly do no clones and mark FINISHED.

Partial failures

If one iteration fails, skip other iterations or keep going?
