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

12 factor app configuration vs leaking environment variables
App configuration in environment variables: for and against
For (some of these as per the 12 factor principles)
1) they are are easy to change between deploys without changing any code
2) unlike config files, there is little chance of them being checked
into the code repo accidentally
3) unlike custom config files, or other config mechanisms such as Java

to say that's interesting? Something about Ruby, perhaps. Maybe the
future of it. The future of something, at least. That sounds
