Parallelization: Making the most of your Machine
From Stat DS Computing Wiki
By default, most programming languages like Python and R will only use one CPU core/thread to execute your code. For small workloads, this is often sufficient even on a personal device. However, larger data processing or analysis workflows will often taken far too long to run on a single core or thread.
Parallelization is the process of taking a large computational task and breaking it into smaller tasks that can all be run simultaneously and independently. For example, most bootstrap methods can be parallelized, since each bootstrap sample is processed independently. This page will introduce several tools and techniques for running parallel workflows.
