Energy-efficient computing is becoming more important with the latest technology improvements. State-of-the-art dynamic voltage/frequency scaling (DVFS) policies manage resources' voltage and frequency to achieve higher energy efficiency. A DVFS policy manages a single resource by continuously evaluating its utilization. We propose a new integrated DVFS policy that manages both CPU and memory. The policy selects their frequency/voltage based on resources' combined state, rather than evaluating isolated information about each resource. For the SPEC CPU2006 benchmark, results show that our policy has an average of 9.04% energy efficiency improvement for CPU and memory compared to 4.84% savings by an independent policy.

A Distributed Monitoring and Reconfiguration Approach for Adaptive Network Computing Bhargava, Bharat; Angın, Pelin; Ranchal, Rohit; Lingayat, Sunil (2015-01-01) The past decade has witnessed immense developments in the field of network computing thanks to the rise of the cloud computing paradigm, which enables shared access to a wealth of computing and storage resources without needing to own them. While cloud computing facilitates on-demand deployment, mobility and collaboration of services, mechanisms for enforcing security and performance constraints when accessing cloud services are still at an immature state. The highly dynamic nature of networks and clouds ma...
Analyzing of usage of complex-shaped Cu-W parts produced by metal injection molding process for heat sink for high-performance electronic devices Atak, Alper; Kalkanlı, Ali; Department of Metallurgical and Materials Engineering (2019) During the past decades, the rapid evolution of electronic and information technology has resulted in a significant increase in the performance of the processors of the electronic devices. In order to dissipate the heat generated at the interface of these electronic devices, heat spreaders or heat sinks should be produced from suitable materials. Thermal conductivity and coefficient of thermal expansion(CTE) are two important thermal properties to consider for choosing the suitable materials for this proces...
Development of a web-based dynamic scheduling methodology for a flexible manufacturing cell using agent based distributed internert applications Alataş, Boran; Anlağan, Ömer; Department of Mechanical Engineering (2004) The increasing importance of computer leads to develop new manufacturing methods. One of the most important example; 3unmanned shop floor4 model aims, the mankind can work in jobs that they can be more efficient and more comfortable. As the base of this model, in Middle East Technical University Computer Integrated Manufacturing Laboratory (METUCIM) 3Agent Version 1.14 system is developed. Windows Distributed Internet Applications (DNA) modeling technique is used for the software development. In the develop...
A new approach to mathematical water quality modeling in reservoirs: Neural networks Karul, C; Soyupak, S; Germen, E (1998-01-01) Neural Networks are becoming more and more valuable tools for system modeling and function approximation as computing power of microcomputers increase. Modeling of complex ecological systems such as reservoir limnology is very difficult since the ecological interactions within a reservoir are difficult to define mathematically and are usually system specific. To illustrate the potential use of Neural Networks in ecological modeling, a software was developed to train the data from Keban Dam Reservoir by back...
A Self-Cloning Agents Based Model for High-Performance Mobile-Cloud Computing Angın, Pelin; Jin, Zhongjun (2015-07-02) The rise of the mobile-cloud computing paradigm in recent years has enabled mobile devices with processing power and battery life limitations to achieve complex tasks in real-time. While mobile-cloud computing is promising to overcome the limitations of mobile devices for real-time computing, the lack of frameworks compatible with standard technologies and techniques for dynamic performance estimation and program component relocation makes it harder to adopt mobile-cloud computing at large. Most of the avai...
