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

	Twitter's API doesn't allow you to get replies to a particular tweet. Strange
	but true. But you can use Twitter's Search API to search for tweets that are
	directed at a particular user, and then search through the results to see if
	any are replies to a given tweet. You probably are also interested in the
	replies to any replies as well, so the process is recursive. The big caveat
	here is that the search API only returns results for the last 7 days. So
