Dieses Buch enthalt die Beitrage der 5. GI/ITG-Fachtagung uber Messung, Modellierung und Bewertung von Rechensystemen und Netzen, die im September 1989 in Braunschweig veranstaltet wurde. Inhalt dieser wichtigsten deutschen Tagung auf diesem Gebiet war der Austausch neuer Ideen und Erfahrungen bei der quantitativen Untersuchung von Rechensystemen und Netzen. Dabei wurde einerseits das volle methodische Spektrum - Messinstrumentierung/Messung - Modellbildung/simulative und mathematische Modellanalyse - Bewertung und Synthese in leistungsorientierter bzw. leistungs-/ zuverlassigkeitsorientierter Sicht abgedeckt sowie andererseits uber praktische Erfahrungen beim Einsatz dieser Methoden und Techniken bei Entwurf, Implementierung/Installierung und Betrieb einzelner und vernetzter Rechensysteme berichtet. Die Beitrage behandeln Methoden und Techniken der Beschreibung und Untersuchung von Systemen hinsichtlich ihrer Leistungsfahigkeit und Zuverlassigkeit, (Hard- und Software-) Mess- und Monitorsysteme, Charakterisierung von Systembelastungen, Erstellung und simulative mathematische/hybride Analyse von Systemmodellen sowie Erfahrungen bei der Bewertung und Optimierung von Rechensystemen und Netzen."

Seit 1986 trifft sich in Mannheim jahrlich auf Einladung des Vereins zur wissenschaftlichen Weiterbildung der Universitat Mannheim e.V. die deutschsprachige Supercomputergemeinde - Anwender, Betreiber, Hersteller - zu einem fruchtbaren Dialog und Erfahrungsaustausch. In dem diesjahrigen Seminar "Supercomputer - Anwendungen, Architekturen und Trends" werden die neuesten Entwicklungen dieses stark innovativen Gebiets unter einem sehr anwendungsbezogenen, praktischen Aspekt aufgearbeitet. Experten aus dem Inland sowie den nach wie vor fuhrenden Landern USA und Japan konnten auch bei dieser zum vierten Mal stattfindenden Veranstaltung zu Prasentationen gewonnen werden. Alle Beitrage zum Seminar sind in diesem Band enthalten. Insbesondere befassen sie sich mit folgenden Schwerpunkten: - Visualisierung/Mensch-Maschine-Schnittstelle - Architekturen - Parallel versus vector processing - Innovative Anwendungen."

According to Apple, there are currently 380,000 registered iOS developers and over a billion iOS devices in use worldwide. Swift, the language of iOS development, is the fastest growing programming language. iOS Development with Swift is a hands-on guide to creating apps for iPhone and iPad using the Swift language. It starts by giving a birdseye view of how an iOS application works and what it takes to build one. With the basics well in hand, the book takes readers through progressively more challenging examples as they learn how to design iOS apps, build good layouts, handle navigation, and interact with the device's camera. Key Features: * Hands-on guide to creating apps * Teaches the very basics * Rich in examples Written for readers with experience using a language like Java, Python, or C#. No prior iOS development or Swift experience required. About the Technology: Swift is a modern language created by Apple. In 2015 Swift was rated the most loved programming language on Stack Overflow, and it is currently ranked 17 in the programming language rankings guide of January 2016.

Unleash the power of declarative programming in SwiftUI by building cross-platform Apple apps for iOS 15, macOS, and watchOS using Swift 5.5, Xcode 13, and SwiftUI 3 Key Features Apply the declarative programming paradigm to build cross-platform UIs for Apple devices Learn to integrate UIkit, Core Data, Firebase, and Sign in with Apple with SwiftUI Adopt the new SwiftUI 3.0 features to build visually appealing UIs speedily Book DescriptionSwiftUI provides an innovative and simple way to build beautiful user interfaces (UIs) for all Apple platforms, from iOS and macOS through to watchOS and tvOS, using the Swift programming language. In this recipe-based cookbook, you'll cover the foundations of SwiftUI as well as the new SwiftUI 3 features introduced in iOS 15 and explore a range of essential techniques and concepts that will help you through the development process. The cookbook begins by explaining how to use basic SwiftUI components. Once you've learned the core concepts of UI development, such as Views, Controls, Lists, and ScrollViews, using practical implementations in Swift, you'll advance to adding useful features to SwiftUI using drawings, built-in shapes, animations, and transitions. You'll understand how to integrate SwiftUI with exciting new components in the Apple development ecosystem, such as Combine for managing events and Core Data for managing app data. Finally, you'll write iOS, macOS, and watchOS apps by sharing the same SwiftUI codebase. By the end of this SwiftUI book, you'll have discovered a range of simple, direct solutions to common problems encountered when building SwiftUI apps. What you will learn Explore various layout presentations in SwiftUI such as HStack, VStack, LazyHStack, and LazyVGrid Create widgets to quickly display relevant content at glance Get up to speed with drawings in SwiftUI using built-in shapes, custom paths, and polygons Discover modern animation and transition techniques in SwiftUI Add user authentication using Firebase and Sign in with Apple Manage concurrency with Combine and async/await in SwiftUI Solve the most common SwiftUI problems, such as integrating a MapKit map, unit testing, snapshot testing, and previewing layouts Who this book is forThis book is for mobile developers who want to learn SwiftUI as well as experienced iOS developers transitioning from UIkit to SwiftUI. The book assumes knowledge of the Swift programming language. Knowledge of object-oriented design and data structures will be useful but not necessary. You'll also find this book to be a helpful resource if you're looking for reference material regarding the implementation of various features in SwiftUI.

Overcome the challenges and complexities involved in creating your own shaders with high-level realism using practical solutions, best practices, and the latest features of Unity 2021 Key Features Discover practical recipes for mastering post-processing effects and advanced shading techniques Learn the secrets of creating AAA quality shaders without writing long algorithms Create visually stunning effects for your games using Unity's VFX Graph Book DescriptionShaders enable you to create powerful visuals for your game projects. However, creating shaders for your games can be notoriously challenging with various factors such as complex mathematics standing in the way of attaining the level of realism you crave for your shaders. The Unity 2021 Shaders and Effects Cookbook helps you overcome that with a recipe-based approach to creating shaders using Unity. This fourth edition is updated and enhanced using Unity 2021 features and tools covering Unity's new way of creating particle effects with the VFX Graph. You'll learn how to use VFX Graph for advanced shader development. The book also features updated recipes for using Shader Graph to create 2D and 3D elements. You'll cover everything you need to know about vectors, how they can be used to construct lighting, and how to use textures to create complex effects without the heavy math. You'll also understand how to use the visual-based Shader Graph for creating shaders without any code. By the end of this Unity book, you'll have developed a set of shaders that you can use in your Unity 3D games and be able to accomplish new effects and address the performance needs of your Unity game development projects. So, let's get started! What you will learn Use physically based rendering to fit the aesthetic of your game Create spectacular effects for your games by testing the limits of what shaders can do Explore advanced shader techniques for your games with AAA quality Use Shader Graph to create 2D and 3D elements for your games without writing code Master the math and algorithms behind the commonly used lighting models Get to grips with the Post-Processing Stack to tweak the appearance of your game Who this book is forThis book is for game developers who want to start creating their first shaders in Unity 2021 and take their game to a whole new level by adding professional post-processing effects.
