Professional and Applied Computing (R0)

This book will teach you fundamental mathematical concepts using Unity-based custom examples, explaining the implementations and demonstrating how these concepts are applied in building modern video game functionality. You will learn the theoretical foundation of each concept, and then interact, examine, and modify the implementation to inspect the effects.

Basic Math for Game Development with Unity 3D begins by explaining points in the 3D Cartesian Coordinate system. From there, you’ll gain insight into vectors and details of dot and cross products, quaternions, rotation and decomposition of vectors. These basic mathematical foundations are illustrated through Unity-based example implementations. Associated with these concept presentations are separate examples of how the concepts are applied in creating typical video game functionality, such as collision support, motion simulations, autonomous behaviors, shadow approximations, and reflections off surfaces with arbitrary orientations. 

After completing this book, you will have a thorough understanding of core mathematical concepts and how they are used to create compelling gameplay.

 What You Will Learn

• Understand the basic concepts of points and vectors, and their applications in game development
• Grasp the details of autonomous behaviors such as facing a target, following and chasing an object, and more
• Apply mathematical concepts in implementing modern video game functionality such as ray casting, collision, and motion control

 Who Is This Book For

Supercomputers and High Performance Computing (HPC) clusters are not so exotic as people imagine these days. They give companies the power of computation like no one server can give alone.  They make new drugs and materials discoveries, universe modeling and AI training, crash simulations and market research possible – all thanks to HPC clusters. Building or renting a HPC cluster is not so difficult either as cloud providers can give you resources to build one cheap and performative enough to use yourself, so If you are or want to become HPC cluster Sysadmin or manager, this book is for you.

Supercomputers for Linux SysAdmins delves into the world of modern HPC cluster architecture, hardware, software and resources management using a Linux/UNIX based approach. The number of HPC clusters is growing with an estimated 30 billion by 2030 but there are not enough sysadmins to run and manage them, this book serves to bridge this gap to help more Sysadmins and managers to transition into the exiting world of HPCs. 

This book helps those with a strong foundational knowledge in Linux, to deal with supercomputers and HPC clusters. We start with the basic principles of supercomputer management, fundamentals of Linux and UNIX, Shell Scripting and systemd and well as other open source tools and frameworks, taking you thorough the security, monitoring and hardware requirements for supercomputers and HPC clusters.

You Will Learn:

• How to plan new supercomputers
• The main principles and technologies used in supercomputers and HPC clusters
• How to set up the software environments on new supercomputers 
• To set up supercomputer and HPC cluster resources and jobs management
• To manage accounts, resource sharing and many more.

Who is it for: 

The main audience of this book are regular UNIX/Linux sysadmins and managers, who should deal with HPC clusters on-prem or in cloud and those who are interested in supercomputers and HPC clusters and how to utilize them in their projects and teams.
