run_tasks
- sherpa.utils.parallel.run_tasks(procs, err_q, out_q, num=None)[source] [edit on github]
Run the processes, exiting early if necessary, and return the results.
Changed in version 4.16.0: The num argument is not needed and has been marked optional. It will be removed in a future release.
- Parameters:
procs (list of multiprocessing.Process tasks) – The processes to run.
err_q (manager.Queue) – The error and success channels used by the processes.
out_q (manager.Queue) – The error and success channels used by the processes.
num (optional) – This argument is unused and will be removed.
- Returns:
result – The result from the processes. This may contain more elements than procs, as each process may return multiple results.
- Return type:
Notes
Each process sends its output - a pair with index and a list of results - to the out_q queue, and any error encounteded to the err_q queue. There should be len(procs) messages sent to the out_q queue for a successful run.
