parsl.dataflow.dependency_resolvers.SHALLOW_DEPENDENCY_RESOLVER = DependencyResolver(traverse_to_gather=<function shallow_traverse_to_gather>, traverse_to_unwrap=<function shallow_traverse_to_unwrap>)

A DependencyResolver describes how app dependencies can be resolved. It is specified as two functions: traverse_to_gather which turns an app parameter into a sequence of futures which must be waited for before the task can be executed (for example, in the case of DEEP_DEPENDENCY_RESOLVER this traverses structures such as lists to find every contained Future), and traverse_to_unwrap which turns an app parameter into its value to be passed to the app on execution (for example in the case of DEEP_DEPENDENCY_RESOLVER this replaces a list containing futures with a new list containing the values of those resolved futures).

By default, Parsl will use SHALLOW_DEPENDENCY_RESOLVER which only resolves Futures passed directly as arguments.
