Design of Multithreaded Software: The Entity-Life Modeling Approach Hardback - 2011 - 1st Edition

A novel approach to designing software for reactive systems

This book is the first available in-depth introduction to the cutting-edge entity-life modeling (ELM) approach for the design of multithreaded, reactive software, making it an instant authoritative reference. The text is divided into three parts:

• Part I covers two fundamentals necessary for understanding ELM--program-language thread support in Ada and Java, and state modeling

• Part II describes ELM's unique approach

• Part III positions ELM relative to other design approaches

Reactive software must respond to events in the world as they occur. To deal with this, ELM defines an event thread as a series of event occurrences that are separated in time. As the book reveals, event threads become the basis for software threads, leading to thread architectures that can be understood intuitively in problem-domain terms. Readers will discover how ELM captures the logic of event threads in terms of states, providing two patterns for designing software threads based on state diagrams and their activities.

Event threads in the domain can also form patterns. The text explains how ELM identifies the resource-user-thread pattern and the resource-guard-thread pattern, both addressing resource sharing by multiple domain entities. It also covers the case where entities need simultaneous exclusive access to more than one resource, and shows how ELM deals with deadlock prevention.

Design of Multithreaded Software is intended for software designers, architects, and researchers as well as systems designers, programmers, and engineers interested in a practical account of this novel approach.
