atomica.utils.parallel_progress

atomica.utils.parallel_progress(fcn, inputs, num_workers=None, show_progress=True)[source]

Run a function in parallel with a optional single progress bar

The result is essentially equivalent to

>>> list(map(fcn, inputs))

But with execution in parallel and with a single progress bar being shown. The Atomica logger level will be changed to hide output below the WARNING level.

Parameters
  • fcn – Function object to call, accepting one argument, OR a function with zero arguments in which case inputs should be an integer

  • inputs – A collection of inputs that will each be passed to (list, array, etc.) OR a number, if the fcn() has no input arguments

  • num_workers – Number of processes, defaults to the number of CPUs

Return type

list

Returns

An list of outputs
