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

	@moduledoc """
	Exposes functions to make HTTP requests and optionally cache the response.

	If you want to cache the request, simply add `cache: true` to the
	request options. You can also define an option time-to-live (TTL) with
	`cache_ttl: ttl_in_milliseconds`. The default TTL is 5min.

	Only caches 2xx responses.
