# Introduction

On the previous building linux kernel entry we learn how to configure, modify and install a downloaded linux kernel version on our Ubuntu distribution. In this tutorial, we will use an existing configuration from the available from each supported architecture. Later, it will be tested on an open source machine emulator called QEmu which supports ARM architecture, unlike Virtual Box.

# Introduction

Shaders are the *modern way* to work with vertex. They are little functions provide us a great flexibility to transform the vertex through a standard pipeline.

LU factorization is a popular method to decompose a matrix as the product of a Lower triangle and an Upper triangle matrices. Lot of simulations perform the solving of a given system of linear equations. In general, the resolution of these systems is quite hard so matrix decomposition method is frequently used to subdivide the problem. As it's easier to solve a triangular matrix than a standard matrix, this is usually the first step on many simulations.
