ParslExecutor
[source]¶ Define the strict interface for all Executor classes.
This is a metaclass that only enforces concrete implementations of functionality by the child classes.
In addition to the listed methods, a ParslExecutor instance must always have a member field:
- label: str - a human readable label for the executor, unique
- with respect to other executors.
An executor may optionally expose:
- storage_access: List[parsl.data_provider.staging.Staging] - a list of staging
providers that will be used for file staging. In the absence of this attribute, or if this attribute is
None
, then a default value ofparsl.data_provider.staging.default_staging
will be used by the staging code.Typechecker note: Ideally storage_access would be declared on executor __init__ methods as List[Staging] - however, lists are by default invariant, not co-variant, and it looks like @typeguard cannot be persuaded otherwise. So if you’re implementing an executor and want to @typeguard the constructor, you’ll have to use List[Any] here.
