Introduction to the special issue on sustainable and green computing systems
Partha Pratim Pande, Amlan Ganguly
Article No.: 26
A world consisting of billions of service-oriented client devices and thousands of data centers can deliver a diverse range of services, from social networking to management of our natural resources. However, these services must scale in order to...
Technology-driven limits on runtime power management algorithms for multiprocessor systems-on-chip
Siddharth Garg, Diana Marculescu, Radu Marculescu
Article No.: 28
Runtime power management is a critical technique for reducing the energy footprint of digital electronic devices and enabling sustainable computing, since it allows electronic devices to dynamically adapt their power and energy consumption to meet...
Energy-efficient markov chain-based duty cycling schemes for greener wireless sensor networks
Giacomo Ghidini, Sajal K. Das
Article No.: 29
To extend the lifetime of a wireless sensor network, sensor nodes usually duty cycle between dormant and active states. Duty cycling schemes are often evaluated in terms of connection delay, connection duration, and duty cycle. In this article, we...
Implementing the data center energy productivity metric
Landon H. Sego, Andrés Márquez, Andrew Rawson, Tahir Cader, Kevin Fox, William I. Gustafson, Jr., Christopher J. Mundy
Article No.: 30
As data centers proliferate in size and number, the endeavor to improve their energy efficiency and productivity is becoming increasingly important. We discuss the properties of a number of the proposed metrics of energy efficiency and...
Barely alive memory servers: Keeping data active in a low-power state
Vlasia Anagnostopoulou, Susmit Biswas, Heba Saadeldeen, Alan Savage, Ricardo Bianchini, Tao Yang, Diana Franklin, Frederic T. Chong
Article No.: 31
Current resource provisioning schemes in Internet services leave servers less than 50% utilized almost all the time. At this level of utilization, the servers' energy efficiency is substantially lower than at peak utilization. A solution to...
Energy- and performance-aware scheduling of tasks on parallel and distributed systems
Hafiz Fahad Sheikh, Hengxing Tan, Ishfaq Ahmad, Sanjay Ranka, Phanisekhar Bv
Article No.: 32
Enabled by high-speed networking in commercial, scientific, and government settings, the realm of high performance is burgeoning with greater amounts of computational and storage resources. Large-scale systems such as computational grids consume a...
Enhancing data center sustainability through energy-adaptive computing
Krishna Kant, Muthukumar Murugan, David H. C. Du
Article No.: 33
The sustainability concerns of Information Technology (IT) go well beyond energy-efficient computing and require techniques for minimizing environmental impact of IT infrastructure over its entire life-cycle. Traditionally, IT infrastructure is...
DAHM: A green and dynamic web application hosting manager across geographically distributed data centers
Zahra Abbasi, Tridib Mukherjee, Georgios Varsamopoulos, Sandeep K. S. Gupta
Article No.: 34
Dynamic Application Hosting Management (DAHM) is proposed for geographically distributed data centers, which decides on the number of active servers and on the workload share of each data center. DAHM achieves cost-efficient application hosting by...
