parsl.app.app.python_app

parsl.app.app.python_app(function=None, data_flow_kernel=None, cache=False, executors='all')[source]

Decorator function for making python apps.

Parameters:
  • 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.
