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

// This file is automatically generated, but you can add your own variables here too.
// Syntax: SET_VAR(variable_name, default, low_limit, upper_limit, slider_exponent)
// In code you can read the variable with: GET_VAR(variable_name)
SET_VAR(tower_height, 520.0f, 0.0f, 3000.0f, 1.0f)
SET_VAR(KSpring, 520.0f, 1.0f, 3000.0f, 1.0f)
SET_VAR(WireRadius, 2.0f, 0.1f, 34.0f, 1.0f)
SET_VAR(volcanic_sun_x, 0.088000, -20.0f, 20.0f, 1.0f)
SET_VAR(mothership_sun_x, 2.026000, -5.0f, 5.0f, 1.0f)

WannaCry|WannaDecrypt0r NSA-Cyberweapon-Powered Ransomware Worm

• Virus Name: WannaCrypt, WannaCry, WanaCrypt0r, WCrypt, WCRY
• Vector: All Windows versions before Windows 10 are vulnerable if not patched for MS-17-010. It uses EternalBlue MS17-010 to propagate.
• Ransom: between $300 to $600. There is code to 'rm' (delete) files in the virus. Seems to reset if the virus crashes.
• Backdooring: The worm loops through every RDP session on a system to run the ransomware as that user. It also installs the DOUBLEPULSAR backdoor. It corrupts shadow volumes to make recovery harder. (source: malwarebytes)
• Kill switch: If the website www.iuqerfsodp9ifjaposdfjhgosurijfaewrwergwea.com is up the virus exits instead of infecting the host. (source: malwarebytes). This domain has been sinkholed, stopping the spread of the worm. Will not work if proxied (source).

update: A minor variant of the viru
