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

Powerline-patched Monaco for Windows and OSX

This font is manually patched with Fontforge. It includes the glyphs from DejaVu Sans Mono for Powerline.

I recommend DirectWrite-patched VIM builds. I'm using KaoriYa's build (http://www.kaoriya.net/software/vim/)

Usage

Add the following lines to your .vimrc/_vimrc:

(C-x means ctrl+x, M-x means alt+x)

Prefix key

The default prefix is C-b. If you (or your muscle memory) prefer C-a, you need to add this to ~/.tmux.conf:

remap prefix to Control + a
