Energy efficiency is becoming an increasingly important factor to consider in day-to-day operations, and the Information, Communication and Technology (ICT) arena is no exception. The energy consumption in the ICT sector is increasing at a rate that deems energy consumption a possible limitation to the continuous fast growth of the future Internet. We address this limitation in two ways. (1) We propose...
Energy efficiency and parallel I/O performance are two primary constraints in high performance computing (HPC). Large scale computing systems consume vast amounts of energy and require scalable I/O performance to meet the needs of a broad spectrum of data intensive scientific applications. However, little research has provided an in-depth understanding of energy efficiency in parallel I/O subsystems...
In information system, it is critical to reduce the total electrical power consumption. We have discussed a power consumption model for communication-based applications. Then, we have proposed a pair of PCB (power consumption-based) and TRB (transmission rate-based) algorithms to select a server so that the total power consumption of the servers is reduced. In addition, we showed the PCB algorithm...
It is now critical to reduce the consumption of natural resources, especially petroleum. Even in information systems, we have to reduce the total electrical power consumption. We classify network applications to two types of applications, transaction and communication based ones. In this paper, we consider communication based applications like the file transfer protocol (FTP). A computer named server...
Although most large-scale systems are designed with the network as a central component, the interconnection network's energy consumption has received little attention. However, several software and hardware approaches can increase the interconnection network's power efficiency by using the network more efficiently or using throttling bandwidths to reduce the power consumption of unneeded resources.
