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

Usage

Set a system environment variable AUTHZ_JSON_URL that points to a JSON file with the following structure:

{
  "admins": [
    "groupA", 
    "userA"
 ],

	-- This is an example schema for storing collectd metrics in a TimescaleDB
	-- dabase (see https://www.timescale.com/). It is based on the PostgreSQL
	-- schema contributed by Sebastian Harl.

	-- Prerequisities:
	-- ---------------

	1. Setup a project

	2. Add groovy SDK support:
	https://www.bonusbits.com/wiki/HowTo:Add_Groovy_SDK_to_IntelliJ_IDEA

	3. Download http://(yourjenkinsurl)/job/(yourpipelinejob)/pipeline-syntax/gdsl
	- this will give you the .gdsl file - download this to the src folder of your project.

	4. Finally follow this step - right click on the src folder -> Mark directory as -> Sources Root
