  • A new approach to bottom-up parsing that extends Augmented Context-Free Grammar to a Process Grammar is formally presented. A Process Grammar (PG) defines a set of rules suitedfor bottom-up parsing and conceived as processes that are applied by a P G Processor. The matching phase is a crucial step for process application, and a parsing structure for efficient matching is also presented. The PG Processor is composed of a process scheduler that allows immediate constituent analysis of structures, and behaves in a non-deterministic fashion. ...

  • In chapter 4, we introduced threads to the process model. On operating systems that support them, it is kernel-level threads not processes that are in fact being scheduled by the operating system. However, the terms "process scheduling" and "thread scheduling" are often used interchangeably. In this chapter, we use process scheduling when discussing general scheduling concepts and thread scheduling to refer to thread-specific ideas.

  • Generally speaking, scheduling is the procedure of mapping a set of tasks or jobs (studied objects) to a set of target resources efficiently. It is an important tool in manufacturing and engineering, where it can have a major impact on the productivity of a process. More specifically, as a part of a larger planning and scheduling process, production scheduling is essential for the proper functioning of a manufacturing enterprise. Its primary goal is to maximize throughput and optimize resource utilization, while at the same time minimizing operating costs.

  • Systolic architectures are designed by using linear mapping techniques on regular dependence graphs (DG). Systolic architectures have a space-time representation where each node is mapped to a certain processing element (PE) and is scheduled at a particular time instance. Chapter 7 will discuss the systolic architecture design, inviting you refer.

  • Chapter 4 - Processes, now includes coverage of multitasking in mobile operating systems, support for the multiprocess model in Google’s Chrome web browser, and zombie and orphan processes in UNIX. The objectives of this chapter are to introduce the notion of a process a program in execution, which forms the basis of all computation; to describe the various features of processes, including scheduling, creation, and termination; to explore interprocess communication using shared memory and mes- sage passing.

  • In this chapter we introduce the concept of a process and the notion of concurrent execution. Those are at the very heart of modern operating systems. A process is is a program in execution and is the unit of work in a modern time-sharing system. Such a system consists of a collection of processes: Operating-system processes executing system code, and user processes executing user code. This chapter also discuss the notion of a thread (light-weight process) and interprocess communication (IPC).

  • The chapter describes the process of building and monitoring schedules for software development projects. To build complex software systems, many engineering tasks need to occur in parallel with one another to complete the project on time. The output from one task often determines when another may begin. It is difficult to ensure that a team is working on the most appropriate tasks without building a detailed schedule and sticking to it.
