This book was released on 2006-07-18 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: Real-Time Management of Resource Allocation Systems focuses on the problem of managing the resource allocation taking place within the operational context of many contemporary technological applications, including flexibly automated production systems, automated railway and/or monorail transportation systems, electronic workflow management systems, and business transaction supporting systems. A distinct trait of all these applications is that they limit the role of the human element to remote high-level supervision, while placing the burden of the real-time monitoring and coordination of the ongoing activity upon a computerized control system. Hence, any applicable control paradigm must address not only the issues of throughput maximization, work-in-process inventory reduction, and delay and cost minimization, that have been the typical concerns for past studies on resource allocation, but it must also guarantee the operational correctness and the behavioral consistency of the underlying automated system. The resulting problem is rather novel for the developers of these systems, since, in the past, many of its facets were left to the jurisdiction of the present human intelligence. It is also complex, due to the high levels of choice – otherwise known as flexibility – inherent in the operation of these environments.

This book was released on 2016-09-21 with total page 308 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides a comprehensive state of the art overview of a series of advanced trends and concepts that have recently been proposed in the area of green information technologies engineering as well as of design and development methodologies for models and complex systems architectures and their intelligent components. The contributions included in the volume have their roots in the authors’ presentations, and vivid discussions that have followed the presentations, at a series of workshop and seminars held within the international TEMPUS-project GreenCo project in United Kingdom, Italy, Portugal, Sweden and the Ukraine, during 2013-2015 and at the 1st - 5th Workshops on Green and Safe Computing (GreenSCom) held in Russia, Slovakia and the Ukraine. The book presents a systematic exposition of research on principles, models, components and complex systems and a description of industry- and society-oriented aspects of the green IT engineering. A chapter-oriented structure has been adopted for this book following a “vertical view” of the green IT, from hardware (CPU and FPGA) and software components to complex industrial systems. The 15 chapters of the book are grouped into five sections: (1) Methodology and Principles of Green IT Engineering for Complex Systems, (2) Green Components and Programmable Systems, (3) Green Internet Computing, Cloud and Communication Systems, (4) Modeling and Assessment of Green Computer Systems and Infrastructures, and (5) Green PLC-Based Systems for Industry Applications. The chapters provide an easy to follow, comprehensive introduction to the topics that are addressed, including the most relevant references, so that anyone interested in them can start the study by being able to easily find an introduction to the topic through these references. At the same time, all of them correspond to different aspects of the work in progress being carried out by various research groups throughout the world and, therefore, provide information on the state of the art of some of these topics, challenges and perspectives.

TCCI strives to cover new methodological, theoretical and practical aspects of CCI understood as the form of intelligence that emerges from the collaboration and competition of many individuals (artificial and/or natural). The application of multiple computational intelligence technologies such as fuzzy systems, evolutionary computation, neural systems, consensus theory, etc., aims to support human and other collective intelligence and to create new forms of CCI in natural and/or artificial systems. This second TCCI issue contains a collection of 10 articles selected from high-quality submissions addressing advances in the foundations and applications of computational collective intelligence.
Download or read book Analysis and Design of Resource Allocation Policies for Cloud based Computing Systems Supporting Soft Real time Applications written by Yuhuan Du and published by . This book was released on 2015 with total page 326 pages. Available in PDF, EPUB and Kindle. Book excerpt: Cloud-based computing infrastructure can provide an efficient means to support real-time applications with compute and/or communication deadlines, e.g., virtualized base station processing, and collaborative video conferencing. In many cases, such applications can tolerate occasional deadline violations without substantially impacting their Quality of Service (QoS). A fundamental problem in such systems is deciding how to allocate shared resources so as to meet applications' QoS requirements. A simple framework to address this problem is to, (1) dynamically prioritize users as a possibly complex function of their deficits (difference of achieved vs required QoS), and (2) allocate resources so as to expedite users assigned higher priority. In the first part of this dissertation, we focus on a general class of systems using such priority-based resource allocation. In this setting we characterize the set of feasible QoS requirements. We then consider "simple" weighted Largest Deficit First (w-LDF) prioritization policies, where users with higher weighted deficits are given higher priority. We give an inner bound for the feasible set of QoS requirements under w-LDF policies, and characterize its geometry under an additional monotonicity assumption. Additional insights on the optimality of LDF/hierarchical-LDF are also discussed. In the second part of this dissertation, we consider a specific class of computing systems having multiple uniform resources. We develop a general outer bound on the feasible QoS region for non-clairvoyant resource allocation policies, and study the efficiency and near-optimality of two natural resource allocation policies: (1) priority-based greedy task scheduling for applications with variable workloads, and (2) priority-based task selection and optimal scheduling for applications with deterministic workloads. Analysis and simulations show substantial resource savings for such policies over reservation-based designs. We also discuss user/stream management for computing systems supporting soft real-time users. Overall, the main contribution of this dissertation is a theoretical study on the efficiency and optimality of simple deficit-based resource allocation policies for systems supporting periodically generated, but stochastic workloads requiring soft guarantees on completion times.

Download or read book The Distributed Utility Model Applied to Optimal Admission Control QoS Adaptation in Multimedia Systems Enterprise Networks written by Md Mostofa Akbar and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Allocation and reservation of resources, such as CPU cycles and I/O bandwidth of multimedia servers and link bandwidth in the network, is essential to ensure Quality of Service (QoS) of multimedia services delivered over the Internet. We propose a Distributed Multimedia Server System (DMSS) configured out of a collection of networked multimedia servers where multimedia data are partitioned and replicated among the servers. We also introduce Utility Model-Distributed (UM-D), the distributed version of the Utility Model, for admission control and QoS adaptation of multimedia sessions to maximize revenue from multimedia services for the DMSS. Two control architectures, a centralized and a distributed, have been proposed to solve the admission control problem formalized by the UM-D. In the centralized broker architecture, the admission control in a DMSS can be mapped to the Multidimensional Multiple-choice Knapsack Problem (MMKP), a variant of the classical 0-1 Knapsack Problem. An exact solution of MMKP, an NP-hard problem, is not applicable for the on line admission control problem in the DMSS. We therefore developed three new heuristics, M-HEU, I-HEU and C-HEU for solving the MMKP for on-line real-time admission control and QoS adaptation. We present a qualitative analysis of the performance of these heuristics to solve admission control problems based on the worst-case complexity analysis and the experimental results from different sized data sets. The fully distributed admission control problem in a DMSS, on the other hand, maps to the Multidimensional Multiple-choice Multi Knapsack Problem (MMMKP), a new variant of the Knapsack Problem. We have developed D-HEU and A-HEU, two new distributed heuristics to solve the MMMKP. D-HEU requires a large number of messages and it is not suitable for a on line admission controller. A-HEU finds the solution with fewer messages but achieves less optimality than D-HEU. We have applied the admission control strategy described in the UM-D to the set of Media Server Farms providing streaming videos to users. The performance of different heuristics in the broker has been discussed using the simulation results. We have also shown application of UM-D to Distributed SLA (Service Level Agreement) Controllers in Enterprise Networks. Simulation results and qualitative comparison of different heuristics are also provided.
