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

Decorator function for making python apps.

  • function (function) – Do not pass this keyword argument directly. This is needed in order to allow for omitted parenthesis, for example, @python_app if using all defaults or @python_app(walltime=120). If the decorator is used alone, function will be the actual function being decorated, whereas if it is called with arguments, function will be None. Default is None.

  • data_flow_kernel (DataFlowKernel) – The DataFlowKernel responsible for managing this app. This can be omitted only after calling parsl.dataflow.dflow.DataFlowKernelLoader.load(). Default is None.

  • executors (string or list) – Labels of the executors that this app can execute over. Default is ‘all’.

  • cache (bool) – Enable caching of the app call. Default is False.

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