Abstract

Concurrency control is one of the important problems in operation systems. Various studies have been reported to present different algorithms to address this problem, although a few attempts have been made to represent an overall view of the characteristics of these algorithms and comparison of their capabilities to each other. This paper presents a survey of the current methods for controlling concurrency in operating systems. Classification of current algorithms in operating systems has been proposed. Current concurrency control algorithms are classified into four groups: 1) software-based algorithms, 2) hardware-based algorithms, 3) based operating system, and 4) based on message passing. Furthermore, it presents an analysis of the capabilities and characteristics of current algorithms' in their own category (intra-group comparison analysis) and between different categories (inter-group comparison analysis) to put a light on the way of selecting a proper algorithm for various circumstances in operating systems.
