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

About: CSS Grid for IE11

CSS Grid in IE11 is an implementation based on the 2011 spec, which means we aren't really able to use grids out of the box according to the newer spec. However, Autoprefixer automates a lot of work for us with getting the correct IE11 properties, and it has support for most (if not all?) -ms-grid properties.

There are still some gotchas which Autoprefixer can't help with though:

There is no auto-placement behaviour in the 2011 spec. This means that for IE11, you have to position everything. rather than use the autoplacement ability of grid.
Using minmax() with an auto value is not supported, and will break things - e.g. minmax(auto, 1200px) will not work. To use minmax, you have to specify two positive values - e.g. minmax(500px, 1200px).
grid-gap properties were added in a later spec. To create grid-gaps in IE11, you will need to create separate
