[08x02] Julia Performance Tips and Tools | How to use @time, @profile, @profview, @profview_allocs

In this intermediate-level Julia Programming Language coding tutorial, you'll learn about Julia's Performance Tips and Tools to help you convert your code into high-performance code. You'll learn how to use the @time macro to measure your code's performance and you'll learn how to use Julia's profiler, both in the REPL and in VS Code. Series Prerequisites: Basic knowledge about coding with the Julia Programming Language is required. Students should also know how to perform basic data analysis and data visualization using Julia. Students should also be comfortable using Julia in VS Code and Pluto notebooks. 00:00 Intro 00:32 Overview 01:48 AXPY1: Write Naive Code 07:01 AXPY2: Wrap Code in Function 09:54 AXPY3: Use Arithmetic Operators 13:58 AXPY4: Use Broadcasting 16:16 AXPY5: Use Broadcasting + 32-bit Numbers 18:41 AXPY6: Use LinearAlgebra.axpy!() + 32-bit Numbers 22:40 Profiling 31:41 Recap 33:44 Outro ############################## # Links for this tutorial ############################## # Code for this tutorial (GitHub): https://github.com/julia4ta/tutorials/tree/master/Series%2008/Tutorial%2008x02 # Julia Documentation -- Performance Tips https://docs.julialang.org/en/v1/manual/performance-tips/ # Julia Documentation -- Profiling https://docs.julialang.org/en/v1/manual/profile/ # Julia in VS Code - What's New | David Anthoff, Sebastian Pfitzner | JuliaCon 2022.
