  • 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.

  • 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.

Bộ phân thời cho tiến trình (Process Scheduler-SCHED): Như bạn biết về cơ bản PC vẫn là một hệ thống xử lý đơn tức là chỉ có 1 lệnh thực thi tại một thời điểm. Tuy nhiên các hệ điều hành đa nhiệm(multitask) như Windows, Linux v.v đều cho phép nhiều chương trình chạy cùng một lúc.
