Concurrency is the art of making a computer do (or appear to do) multiple things at once. Historically, this meant inviting the processor to switch between different tasks many times per second. In modern systems, it can also literally mean doing two or more things simultaneously on separate processor cores.
Concurrency is not inherently an object-oriented topic, but Python's concurrent systems provide object-oriented interfaces, as we've covered throughout the book. This chapter will introduce you to the following topics:
- The dining philosophers benchmark
The case study for this chapter will address ways we can speed up model testing and hyperparameter tuning. We can't make the computation go away, but we can leverage a modern, multi-core computer to get it done in less time.
Concurrent processes can become complicated. The basic concepts are fairly simple, but the...
