NeSI held its last training webinar of 2019 this week. There Alex Pletzer, a member of our Computational Science team, demonstrated how you can replace for loops with a single array operation to speed up your code-- a technique known as vectorisation.

This webinar was geared towards novice and advanced coders who plan on coding in a scripting language (Python, R, MATLAB, Julia, etc). Whether you are new to HPC, have HPC experience but mostly code in compiled languages, or something in between, understanding vectorisation will help you write scripted code that is more efficient.
