Then this talk is for you! I will present LIKWID.jl (Like I Knew What I'm Doing), a Julia wrapper around the same-named performance benchmarkig suite, that allows you to analyse the performance of your Julia code by monitoring various hardware performance counters sitting inside of your CPU or GPU.

The proceedings are a community-driven initiative to publish articles of interest to the research and developer communities gathered by JuliaCon, they do not require application processing fees nor a paywall on article, making both producing and accessing the articles possible for all. We will then give a quick tour of the reviewing and publication process which happen transparently in
