 * m1cat: a proof of concept for the M1RACLES vulnerability in the Apple M1.
 * 
 * This program implements a covert channel that can be used to transmit data
 * between two processes when run on the Apple Silicon "M1" CPUs.
 *
 * The channel is slightly lossy due to (presumably) the scheduler sometimes
 * scheduling us on the wrong CPU cluster, so this PoC sends every byte twice
 * together with some metadata/framing bits, which is usually good enough.
 * A better approach would be to use proper FEC or something like that.

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

// When creating shaders for Universal Render Pipeline you can you the ShaderGraph which is super AWESOME!
// However, if you want to author shaders in shading language you can use this teamplate as a base.
// Please note, this shader does not necessarily match perfomance of the built-in URP Lit shader.
// This shader works with URP 7.1.x and above
