In this video we'll introduce the topic of multiprocessing - the second key paradigm of parallel processing in this series. Multiprocessing is a cornerstone of high performance computing, enabling your code to scale efficiently across multiple cores, machines and even entire supercomputing clusters.

In this video, we'll compare multiprocessing and multithreading and give a brief introduction on how to implement multiprocessing code in Julia, using both Distributed.jl (the standard library for distributed processing) and the Message Passing Interface (via MPI.jl).

This module was designed as an MPAGS (Midlands Physics Alliance Graduate School) module and aimed at postgraduates and early career researchers.
