Introduction

Python 3.7

Multiprocessor Framework for single Server

Kwargs To Go

Features:

• Uniform foundation to create multiprocess project modules
• Workload Chunks with header to control output and speed up a specific task
• Chunks get a serial number (ID), findings can be checked in a result dictionary, which ID is missing
• module_loader decouples your Worker imports from Main()
• Categories of Queues, assign Names to Queues and groups of Queues
• Queue list helps to debug your setup and reveals the name, object id and object reference of every Queue
• Print Queue allows formatted print to screen for your processes (blocks)
• No libraries, (Linux, Windows)

Visit the features above in the Examples gitHub repository

or

download the all inclusive PyPi Examples package and execute eisenmp_url in Terminal to start the simpleHTTP Ajax server

All scenarios run on Template Style Modules. Enjoy the descriptions.

How it works

You write two functions and two modules. Let's name them Manager.py and Worker.py.

1. Manager.py defines custom objects and starts a new process, target is module_loader.py (loader)
2. loader imports your (independent) Worker.py module from file system without side effects
3. loader sits in a loop and calls your Worker.py entry function until queue is empty
4. q_feeder iterator sends a STOP message. Your Worker reads STOP, return False and exit.
5. module_loader module then puts a STOP Worker message in all other input queues.
6. Next Worker reads STOP, exit ...
7. Loader runs idle and awaits the internal STOP Process message.

Generators

Variables transfer to worker

The worker should be more flexible. Thus, it needs more structured information.

• Information collector is the ModuleConfiguration class instance. The class can carry any name.
• All instance attributes are stored in a dictionary __dict__. (self.foo will be kwargs.foo)
• The instance dictionary is argument (kwargs) to call the eisenmp start method.
• Kwargs is updated further with queue information and the START_SEQUENCE_NUM of the process, before process start.

Default Queues

• Input worker lists, Output result and stop lists
• Tools, Print, Info

How to run the examples?

Fast PyPi package. eisenmp will be installed also.

In depth. Clone both repos.

eisenmp and eisenmp_examples

Install in editable pip mode.

cd eisenmp
pip3 install -e .  # uninstall (linux pip3) with: pip3 uninstall eisenmp

cd eisenmp_examples
pip3 install -e .  # uninstall with: pip3 uninstall eisenmp_examples

Run the examples. Either local Ajax Web server or terminal menu.

eisenmp_url
# or
eisenmp_menu
