Efficient matrix multiplication

High-Performance Matrix Multiplication

This is a short post that explains how to write a high-performance matrix multiplication program on modern processors. In this tutorial I will use a single core of the Skylake-client CPU with AVX2, but the principles in this post also apply to other processors with different instruction sets (such as AVX512).

Intro

Matrix multiplication is a mathematical operation that defines the product of

A simple shell script to quickly / easily install "pacaur" on archlinux
#!/bin/sh
#
# !!! IMPORTANT !!!
# As of 2017-12-14, pacaur is unmaintained (https://bbs.archlinux.org/viewtopic.php?pid=1755144#p1755144)
# For alternatives see the arch wiki: https://wiki.archlinux.org/index.php/AUR_helpers#Active
# pacaur seems to get occasional updates to fix breaking changes due to pacman updates though.
#
# If you are new to arch, I encourage you to at least read and understand what
# this script does befor blindley running it.
# That's why I didn't make a one-liner out of it so you have an easier time
