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

Unreal Engine Asset Diff/Merge-Tool with Git!

Since unreal engines assets are binary encoded classical text based git diff/merge tools will give up on merge conflicts of unreal assets. But fear not! You can setup your git environment to actually be able to diff/merge these .uasset files by using already built-in functionallity of the unreal editor!

Creating the PowerShell-Script

First of all do we have to create a small PowerShell-Script that copies the diff files into temporary files and to convert relative paths to absolute ones.

bool GetActorPosInScreenSpace(const APlayerController* Player, const AActor& Actor, FVector2D& OutScreenPos)
{
  FVector WorldPosition = Actor->GetActorLocation();
  ULocalPlayer* const LP = Player ? Player->GetLocalPlayer() : nullptr;
  if (LP && LP->ViewportClient)
  {
    // get the projection data
    FSceneViewProjectionData ProjectionData;
    if (LP->GetProjectionData(LP->ViewportClient->Viewport, eSSP_FULL, /*out*/ ProjectionData))
    {
