Abstract:

La rapida crescita di Internet e del numero di host connessi sta portando sempre di più alla nascita di nuove forme di tecnlogie ed applicazioni serverside, facendo del client un thin-client. Il Cloud Computing offre una valida piattaforma a queste nuove tecnologie, ma esso si deve confrontare con diverse problematiche, fra cui la richiesta energetica sempre più crescente, che si ripercuote su un'inevitabile aumento dei gas serra prodotti indirettamente. In questa tesi analizzeremo i problemi energetici legati al Cloud Computing e le possibili soluzioni, andando infine a creare una tassonomi

Abstract:

Energy efficiency has become one of the most important factors in the development of computer systems. Increasingly power-hungry processors and memory subsystem have reinforced the need for aggressive power management. Dynamic voltage scaling has become a common consideration for designing energy efficient CPUs in systems ranging from portable devices to large-scale systems. As applications become more data centric and put more pressure on memory subsystem, managing energy consumption of main memory is also becoming critical. Subsequently in this dissertation, we address the issues in designin

Abstract:

High-performance computing (HPC) systems have become power limited. For instance, the U.S. Department of Energy set a power envelope of 20MW in 2008 for the first exascale supercomputer now expected to arrive in 2021--22. Toward this end, we seek to improve the greenness of HPC systems by improving their performance per watt at the allocated power budget. In this dissertation, we develop a series of models and techniques to manage power at micro-, meso-, and macro-levels of the system hierarchy, specifically addressing data movement and heterogeneity. We target the chip interconnect at the mi

Quando si parla di green information technology si fa riferimento a un nuovo filone di ricerche focalizzate sulle tecnologie ecologiche o verdi rivolte al rispetto ambientale. In prima battuta ci si potrebbe chiedere quali siano le reali motivazioni che possono portare allo studio di tecnologie green nel settore dell’information technology: sono così inquinanti i computer? Non sono le automobili, le industrie, gli aerei, le discariche ad avere un impatto inquinante maggiore sull’ambiente? Certamente sì, ma non bisogna sottovalutare l’impronta inquinante settore IT; secondo una recente indagi

The heavy demands on cloud computing resources have led to a substantial growth in energy consumption of the data transferred between cloud computing parties (i.e., providers, datacentres, users, and services) and in datacentre’s services due to the increasing loads on these services.

Demand response is one of the critical technologies necessary for allowing large-scale penetration of intermittent renewable energy sources in the electric grid. Data centers are especially attractive candidates for providing flexible, real-time demand response services to the grid because they are capable of fast power ramp-rates, large dynamic range, and finely-controllable power consumption.

Massive data centers housing thousands of computing nodes have become commonplace in enterprise computing, and the power consumption of such data centers is growing at an unprecedented rate. Exacerbating such costs, data centers are often over-provisioned to avoid costly outages associated with the potential overloading of electrical circuitry. However, such over provisioning is often unnecessary since a data center rarely operates at its maximum capacity. It is imperative that we realize effective strategies to control the power consumption of the server and improve the energy efficiency of d

Abstract:

To address the issues of climate change and reduce the emissions released into the atmosphere, society and companies, including the financial markets, need to adjust how they act and conduct business. The financial markets are vital in the transition towards a more sustainable society and stock exchanges are a central actor to enhance green finance, enabling green securities to be traded. For stock exchange companies to stand tall and encourage a green transition, they need to be aware of their own internal environmental impact. As society is changing to become more serviceoriented, so is stoc

Abstract:

Les progrès en termes de puissance de calcul ont entraîné de nombreuses évolutions dans le domaine de la science et de ses applications. La résolution de systèmes linéaires survient fréquemment dans le calcul scientifique, comme par exemple lors de la résolution d'équations aux dérivées partielles par la méthode des éléments finis. Le temps de résolution découle alors directement des performances des opérations algébriques mises en jeu.Cette thèse a pour but de développer des algorithmes parallèles innovants pour la résolution de systèmes linéaires creux de grandes tailles.

Abstract:

Problemas de escalonamento cuja função objetivo é o consumo de energia tem sido cada vez mais estudados. Neste trabalho, estudamos o problema conhecido, em inglês, por Dynamic Speed Scaling, um problema de escalonamento de tarefas bem definidas em processadores de velocidade variável, cujo consumo de energia é função da velocidade. Além disso, relacionamos este problema com outro conhecido como MOSP, sigla em inglês para Multi-Organization Scheduling Problem. Neste, queremos escalonar tarefas de múltiplas organizações independentes respeitando certas restrições individuais. Provamos, neste t

Abstract:

This Green IT case study commissioned by Försäkringskassan (FK), the Swedish National Social Insurance Agency, quantifies the environmental performance of the IT infrastructure (IT-IS) in use during 2010 in a lifecycle perspective. Adopting a system view in Green IT analysis can mitigate risks of problem shifts. IT-IS concerns the equipment that enables office automation and external web application services. The size of the FK IT-IS is in the order of 300 branch offices with 14000 pc’s, 2100 printers and a 1 MW data centre hosting 1200 servers, 5 Petabyte of central data storage and serving a

Abstract:

Les vingt dernières années ont vu l’émergence de systèmes sans fil dans la vie de tous les jours. Ils ont rendu possible la création de technologies telles que les téléphones portables, le WiFi ou l’internet mobile qui sont maintenant tenus pour acquis dans la société actuelle. L’impact environnemental des technologies de l’information et des communications connaît une croissance exponentielle et a atteint l’impact de l’industrie du transport aérien. L’initiative d’informatique verte a été lancée en réponse à cette observation pour réduire de 15 à 30% les émissions de gaz à effet de serre en 2

Abstract:

L'industrie des technologies de l'information a une empreinte carbone croissante (2,1 à 3,9 % des émissions mondiales de gaz à effet de serre en 2020), incompatible avec la décarbonation rapide nécessaire pour atténuer le changement climatique. Les centres de calculs y contribuent significativement en raison de leur consommation d'électricité : 1 % de la consommation mondiale en 2018. Pour réduire cette empreinte, les travaux de recherche se sont principalement concentrés sur des mesures d'efficacité énergétique et l'utilisation d'énergies renouvelables. Si ces travaux sont nécessaires, ils en

Abstract:

L'Internet des objets (IoT) se caractérise par une myriade de dispositifs et de composants logiciels géographiquement dispersés ainsi que par une grande hétérogénéité en termes de matériel, de format de données et de protocoles. Au cours des dernières années, les plateformes IoT ont été proposées pour fournir une variété de services aux applications, tels que la découverte de dispositifs, la gestion du contexte et l'analyse des données. Cependant, le manque de standardisation fait que chaque plateforme IoT propose ses propres abstractions, API et patrons d'interactions. Par conséquent, la prog
