processmanager 0.1.1

A multiprocessing process manager for Python programs

processmanager

A multiprocessing process manager for Python programs

It provides:

• Simple offloading of work to other processor cores
• State management for the functions in those processes
  • It is easy to cancel in-progress work, which can be useful if a user clicks 'Cancel' in a GUI
• Logging of exceptions while running offloaded functions
• Streaming of results to main process from generator functions
  • This can help smooth out IPC load curve by avoiding an all-at-once result transfer

Original use case:

• GUI program that calls back-end functions for work
• GUI has a cancel button that should always work, so:
  • the GUI mainloop should not be blocked
  • the called functions should intermittently check if the user has pressed the cancel button
• Want to avoid running new work when the user wants to cancel
• Want to work with generators and multiprocessing
  • e.g. send results constantly to main process instead of all at once

Installation:

• pip install processmanager
