parsl.app.app.AppBase

class parsl.app.app.AppBase(func: Callable, data_flow_kernel: DataFlowKernel | None = None, executors: List[str] | str = 'all', cache: bool = False, ignore_for_cache: Sequence[str] | None = None)[source]

This is the base class that defines the two external facing functions that an App must define.

The __init__ () which is called when the interpreter sees the definition of the decorated function, and the __call__ () which is invoked when a decorated function is called by the user.

__init__(func: Callable, data_flow_kernel: DataFlowKernel | None = None, executors: List[str] | str = 'all', cache: bool = False, ignore_for_cache: Sequence[str] | None = None) → None[source]

Construct the App object.

Parameters:

func (-) – Takes the function to be made into an App

Kwargs:

  • data_flow_kernel (DataFlowKernel): The DataFlowKernel responsible for managing this app. This can be omitted only after calling parsl.dataflow.dflow.DataFlowKernelLoader.load().

  • executors (str|list) : Labels of the executors that this app can execute over. Default is ‘all’.

  • cache (Bool) : Enable caching of this app ?

  • ignore_for_cache (sequence|None): Names of arguments which will be ignored by the caching mechanism.

Returns:

  • App object.

Methods

__init__(func[, data_flow_kernel, ...])

Construct the App object.
