A framework for measuring the performance of distributed programs is presented. This framework includes a model of distributed programs, a description of the measurement principles and methods, and a guideline for implementing these ideas. The author describes a measurement system called the Distributed Programs Monitor (DPM), which he has constructed on the basis of these concepts. DPM has been implemented and used for measurement studies on two different operating systems, DEMOS/MP and Berkeley Unix.

The concept of a digital ecosystem (DE) has been used to explore scenarios in which multiple online services and resources can be accessed by users without there being a single point of control. In previous work we have described how the so-called transaction languages can express concurrent and distributed interactions between online services in a transactional environment. In this paper we outline how transaction languages capture the history of a long-running transaction and highlight the benefits of our true-concurrent approach in the context of DEs. This includes support for the recovery of a long-running transaction whenever some failure is encountered. We introduce an animation tool that has been developed to explore the behaviours of long-running transactions within our modelling environment. Further, we discuss how this work supports the declarative approach to the development of open distributed applications.

Abstract This paper introduces a multi-agent framework for distributed multiplayer game development and simulations. The framework allows the incorporation and experimentation with different strategies of the Players, possibly including intelligent behaviors. The framework consists of a set of generic agent types that must be specialized and configured for a specific game. The framework uses a generic agent that enforces the rules of the game, as well as generic bot-agents that represent the game Players. To support our claims of ...

The authors present the design and implementation of an asynchronous remote operation execution facility, futures, that retains the benefits of the remote procedure call (RPC) abstraction but allows execution to proceed locally in parallel with remote execution and provides extensive support for managing replies. It is shown how this facility can be easily used to support many common interprocess communication

Today’s real-time systems (RTS) are characterized by managing large volumes of dispersed data making real-time distributed data processing a reality. Large business houses need to do distributed processing for many reasons, and they often must do it in order to stay competitive. So, efficient database management algorithms and protocols for accessing and manipulating data are required to satisfy timing constraints of supported applications. Therefore, new research in distributed real-time database systems (DRTDBS) is needed to investigate possible ways of applying database systems technology to real-time systems. This paper first discusses the performance issues that are important to DRTDBS, and then surveys the research that has been done so far on the issues like priority assignment policy, commit protocols and optimizing the use of memory in non-replicated/replicated environment pertaining to distributed real time transaction processing. In fact, this study provides a foundation for addressing performance issues important for the management of very large real time data and pointer to other publications in journals and conference proceedings for further investigation of unanswered research questions.

Automated replenishments programs (ARP) is a recent supply chain innovation. The aim is to provide automated replenishment of products based on real time demand information to the production, warehouses and distribution processes in the supply chain. Due to their relative novelty, the knowledge of ARP is limited especially when it comes to how they are operated and controlled in a

Abstract–In Cellular networks, number of users increase in an exponential manner. As a result of this exponential growth of users, overloading of the system takes place. Besides this, unacceptable delays and high computational cost create a strong prerequisite for efficient location management techniques. Motivated by this fact, a novel user profile based (UPB) scheme is proposed in this paper to track the location of the mobile users.
