This book introduces the fundamental concepts and practical simulation te- niques for modeling different aspects of operating systems to study their g- eral behavior and their performance. The approaches applied are obje- oriented modeling and process interaction approach to discrete-event simu- tion. The book depends on the basic modeling concepts and is more specialized than my previous book: Practical Process Simulation with Object-Oriented Techniques and C++, published by Artech House, Boston 1999. For a more detailed description see the Web location: http://science.kennesaw.edu/~jgarrido/mybook,html. Most other books on performance modeling use only analytical approaches, and very few apply these concepts to the study of operating systems. Thus, the unique feature of the book is that it concentrates on design aspects of operating systems using practical simulation techniques. In addition, the book illustrates the dynamic behavior of different aspects of operating systems using the various simulation models, with a general hands-on approach.

Researches and developers of simulation models state that the Java program ming language presents a unique and significant opportunity for important changes in the way we develop simulation models today. The most important characteristics of the Java language that are advantageous for simulation are its multi-threading capabilities, its facilities for executing programs across the Web, and its graphics facilities. It is feasible to develop compatible and reusable simulation components that will facilitate the construction of newer and more complex models. This is possible with Java development environments. Another important trend that begun very recently is web-based simulation, i.e., and the execution of simulation models using Internet browser software. This book introduces the application of the Java programming language in discrete-event simulation. In addition, the fundamental concepts and prac tical simulation techniques for modeling different types of systems to study their general behavior and their performance are introduced. The approaches applied are the process interaction approach to discrete-event simulation and object-oriented modeling. Java is used as the implementation language and UML as the modeling language. The first offers several advantages compared to C++, the most important being: thread handling, graphical user interfaces (QUI) and Web computing. The second language, UML (Unified Modeling Language) is the standard notation used today for modeling systems as a collection of classes, class relationships, objects, and object behavior.

The main objective of this research was to define, design and prototype an open, object-oriented environment consisting of a variety of integrated tools for modeling, analysis, simulation and engineering of computer / communications and other systems such as information systems, business operations and production systems. This environment was to overcome certain problems seen with simulation environments that existed at the time and still persist today. These problems include the lack of: i) a simple to use yet effective performance modeling tool set and ii) an open, integrated, object oriented performance modeling environment using a common programming language and promoting reuse. This report summarizes the results obtained in addressing these problems including an overview of the tools and environments that were prototyped as part of this effort as well as their applications to the performance analysis of some specific communications systems. Issues related to training and education in the use of these tools and environments are also addressed.

Equation-based object-oriented (EOO) modeling languages such as Modelica provide a convenient, declarative method for describing models of cyber-physical systems. Because of the ease of use of EOO languages, large and complex models can be built with limited effort. However, current state-of-the-art tools do not provide the user with enough information when errors appear or simulation results are wrong. It is of paramount importance that such tools should give the user enough information to correct errors or understand where the problems that lead to wrong simulation results are located. However, understanding the model translation process of an EOO compiler is a daunting task that not only requires knowledge of the numerical algorithms that the tool executes during simulation, but also the complex symbolic transformations being performed. As part of this work, methods have been developed and explored where the EOO tool, an enhanced Modelica compiler, records the transformations during the translation process in order to provide better diagnostics, explanations, and analysis. This information is used to generate better error-messages during translation. It is also used to provide better debugging for a simulation that produces unexpected results or where numerical methods fail. Meeting deadlines is particularly important for real-time applications. It is usually essential to identify possible bottlenecks and either simplify the model or give hints to the compiler that enable it to generate faster code. When profiling and measuring execution times of parts of the model the recorded information can also be used to find out why a particular system model executes slowly. Combined with debugging information, it is possible to find out why this system of equations is slow to solve, which helps understanding what can be done to simplify the model. A tool with a graphical user interface has been developed to make debugging and performance profiling easier. Both debugging and profiling have been combined into a single view so that performance metrics are mapped to equations, which are mapped to debugging information. The algorithmic part of Modelica was extended with meta-modeling constructs (MetaModelica) for language modeling. In this context a quite general approach to debugging and compilation from (extended) Modelica to C code was developed. That makes it possible to use the same executable format for simulation executables as for compiler bootstrapping when the compiler written in MetaModelica compiles itself. Finally, a method and tool prototype suitable for speeding up simulations has been developed. It works by partitioning the model at appropriate places and compiling a simulation executable for a suitable parallel platform.

The current state of art in performance technology does not facilitate detailed performance evaluation of complex, large scale systems. The aim of the Phase 1 effort was to demonstrate the feasibility of an Integrated Multi-Level Performance Framework for Complex Systems (IMPACT) for simulation of a parallel database system. As described in this report, the Phase 1 effort resulted in the design and an initial implementation of an object oriented scalable simulator. A prototype model to simulate a parallel database machine was developed and the model was used to simulate the performance of a database running on a shared nothing architecture. The model was developed using three different simulators: CSIM, a commercial sequential simulator, (3) PARSEC, an existing C based parallel discrete event simulator, and COMPOSE, a new C++ library for parallel discrete event simulation. The parallel models were validated against the functionally equivalent CSIM model and were found to produce identical outputs. The performance of the parallel models was subsequently studied for different workloads and substantial performance improvements were observed from parallel execution of the model. Based on the positive results obtained from the Phase 1 study, we have initiated development of a state of the art performance modeling tool for scalable data base systems using the COMPOSE parallel object oriented simulator.
