Dynamic voltage and frequency scaling (DVFS) is a mechanism adopted by major hardware vendors to reduce power demand during times of low processor utilization. However, reducing processor frequency to decrease power demand usually results in degraded services' performance leading to service level agreement violations. Governors, which are a piece of ...

We present a stochastic recursion based discrete-event model of a high-performance computing cluster with service rate switching capabilities. The model is easily adopted to many common settings of modern supercomputers, such as speci?c scheduling disciplines and various control policies. We also provide some illustrative numerical experiments and discuss further generalizations ...

The existing electromobility (EM) is still in its fledgling stage and multiple challenges have to be overcome to make Electric Vehicles (EVs) as convenient as combustion engine vehicles. Users and Electric Vehicle Fleet Operators (EFOs) want their EVs to be charged and ready for use at all times. This straightforward ...

Dynamic Voltage and Frequency Scaling (DVFS) has become a key technique to reduce power consumption at times of low processor (CPU) utilisation. Reducing CPU frequency usually results in degraded services' performance leading to Service Level Agreement (SLA) violations. Usually, CPU governors change frequency and voltage at discrete time instances based ...

To maintain an energy footprint as low as possible, data centres manage their VMs according to conventional and established rules. Each data centre is however made unique due to its hardware and workload specificities. This prevents the ad hoc design of current VM managers from taking these particularities into account ...

Demand Response mechanisms serve to preserve the stability of the power grid by shedding the electricity load of the consumers during power shortage situations in order to match power generation to demand. Data centres have been identified as excellent candidates to participate in such mechanisms. Recently a novel supply demand ...

With the emergence of multi-core processors and their P-states, deriving power consumption models expressed in terms of easily extractable parameters becomes a necessity. In this paper, we introduce a generic methodology to devise power consumption estimation models for multi-core processors. The proposed approach takes into account three metrics: The number ...

Demand Response is a mechanism used in power grids to manage customers' power consumption during critical situations (e.g. power shortage). Data centres are good candidates to participate in Demand Response programs due to their high energy use. In this paper, we present a generic architecture to enable Demand Response between ...

In recent years energy-aware computing has become a major topic, not only in wireless and mobile devices but also in devices using wired technology. The ICT industry is consuming an increasing amount of energy and a large part of the consumption is generated by large-scale data centers. In High-Performance Computing ...

Recently, energy-efficient computing has become a major interest, both in the mobile and IT sectors. With the advent of multi-core processors and their energy-saving mechanisms, there is a necessity to model their power consumption. The existing models for multi-core processors are based on the assumption that the power consumption of ...

Until recently, there have been relatively few studies exploring the power consumption of ICT resources in data centres. In this paper, we propose a methodology to capture the behaviour of most relevant energy-related ICT resources in data centres and present a generic model for them. This is achieved by decomposing ...

Until recently, there have been no efforts of devising energy-efficient replication protocols for large-scale distributed systems. In this paper, we introduce an approach that reduces the energy cost of a particular tree-structured replication protocol. We show that, by shutting down some replicas and by a simple logical structural transformation (rearrangement), ...

Traditional replication protocols that arrange logically the replicas into a tree structure have reasonable availability, low communication costs but induce high system load. We propose in this paper the arbitrary protocol: a tree-based replica control protocol that can be configured based on the frequencies of read and write operations in ...

In large-scaled environments such as Computing Grids, data replication is used to permit a better bandwidth usage of the network. Nevertheless, high latency time exposes the replica management protocols to potential performance degradations. Two new protocols are presented in this paper1 in order to avoid this degradation. Their goal is ...
