How much faster could your python code run (if it used all CPU cores)?
The ProcessPoolExecutor class provides modern process pools for CPU-bound tasks.
This is not some random third-party library, this is a class provided in the Python standard library (already installed on your system).
This is the class you need to make your code run faster.
There's just one problem. No one knows about it (or how to use it well).
Introducing: "Python ProcessPoolExecutor Jump-Start". A new book designed to teach you modern process pools in Python, super fast!
You will get a rapid-paced, 7-part course to get you started and make you awesome at using the ProcessPoolExecutor.
Including:
- How to create process pools and when to use them.
- How to configure process pools including the number of workers.
- How to execute tasks with worker processes and handle results.
- How to execute tasks in the process pool asynchronously.
- How to query and get results from handles on asynchronous tasks called futures.
- How to wait on and manage diverse collections of asynchronous tasks.
- How to develop a parallel Fibonacci calculator 4x faster than the sequential version.
Each of the 7 lessons was carefully designed to teach one critical aspect of the ProcessPoolExecutor, with explanations, code snippets and worked examples.
Each lesson ends with an exercise for you to complete to confirm you understood the topic, a summary of what was learned, and links for further reading if you want to go deeper.
