Detectability of Discrete Event Systems

by Shaolong Shu, Feng Lin, Hao Ying
"... In this paper, we investigate the detectability problem in discrete event systems. We assume that we do not know initially which state the system is in. The problem is to determine the current and subsequent states of the system based on a sequence of observation. The observation includes partial ev ..."

Parallel discrete event simulation

by Richard M. Fujimoto , 1990
"... Parallel discrete event simulation (PDES), sometimes I called distributed simulation, refers to the execution of a single discrete event simulation program on a parallel computer. PDES has attracted a considerable amount of interest in recent years. From a pragmatic standpoint, this interest arises ..."

Time, Clocks, and the Ordering of Events in a Distributed System

by Leslie Lamport , 1978
"... The concept of one event happening before another in a distributed system is examined, and is shown to define a partial ordering of the events. A distributed algorithm is given for synchronizing a system of logical clocks which can be used to totally order the events. The use of the total ordering i ..."

Distributed Database Systems

by M. Tamer Özsu
"... this article, we discuss the fundamentals of distributed DBMS technology. We address the data distribution and architectural design issues as well as the algorithms that need to be implemented to provide the basic DBMS functions such as query processing, concurrency control, reliability, and replica ..."

A public key cryptosystem and a signature scheme based on discrete logarithms

by Taher Elgamal - ADV. IN CRYPTOLOGY, SPRINGER-VERLAG , 1985
"... A new signature scheme is proposed, together with an implementation of the Diffie-Hellman key distribution scheme that achieves a public key cryptosystem. The security of both systems relies on the difficulty of computing discrete logarithms over finite fields. ..."

Virtual time

by David R. Jefferson - ACM Transactions on Programming Languages and Systems , 1985
"... Virtual time is a new paradigm for organizing and synchronizing distributed systems which can be applied to such problems as distributed discrete event simulation and distributed database concur-rency control. Virtual time provides a flexible abstraction of real time in much the same way that virtua ..."

An Integrated Experimental Environment for Distributed Systems and Networks

by Brian White, Jay Lepreau, Leigh Stoller, Robert Ricci, Shashi Guruprasad, Mac Newbold, Mike Hibler, Chad Barb, Abhijeet Joglekar - In Proc. of the Fifth Symposium on Operating Systems Design and Implementation , 2002
"... Three experimental environments traditionally support network and distributed systems research: network emulators, network simulators, and live networks. The continued use of multiple approaches highlights both the value and inadequacy of each. Netbed, a descendant of Emulab, provides an experimenta ..."

Virtual time and global states of distributed systems.

by Friedemann Mattern - Proc. Workshop on Parallel and Distributed Algorithms, , 1989
"... Abstract A distributed system can be characterized by the fact that the global state is distributed and that a common time base does not exist. However, the notion of time is an important concept in every day life of our decentralized \ r eal world" and helps to solve problems like getting a c ..."

consistent population census or determining the potential causality between events. We argue that a linearly ordered structure of time is not (always) adequate for distributed systems and propose a generalized non-standard m o del of time which consists of vectors of clocks. These clock-vectors are p
