Texto completo da fonteIl presente lavoro di tesi tratta la realizzazione di sistemi hardware e software per Quantum Random Number Generation (QRNG) e Quantum Key Distribution (QKD). Tali sistemi sono stati sviluppati al fine di garantire una completa funzionalità per l’investigazione a tutto campo di queste due applicazioni che ad oggi risultano essere le più promettenti nell’ambito della Quantum Information. Vengono presentati in dettaglio sia l’hardware sia i software utilizzati che sono stati sviluppati per schede FPGA-CPU, dispositivi di Time-to-Digital converter (TDC) e computer. Vengono inoltre descritte le applicazioni specifiche di QRNG e QKD assieme ai risultati ottenuti. Randy è stato il primo dispositivo QRNG sviluppato su scheda FPGA e utilizza una sorgente luminosa attenuata a singolo fotone e un single-photon avalanche diode (SPAD). A partire dal campionamento del segnale elettrico dello SPAD, il dispositivo produce numeri randomici tramite protocolli di generazione appositi e tramite l’applicazione dell’algoritmo di unbiasing di Peres per massimizzare il bit rate. Il dispositivo permette inoltre di generare numeri randomici in tempo reale. Questa caratteristica viene utilizzata per la gestione temporizzata di componenti elettro-ottici per l’estensione allo spazio dell’esperimento a scelta ritardata di Wheeler’s. Le stesse tecniche sono state in seguito applicate ad un secondo dispositivo, LinoSPAD, che integra un chip FPGA e un array di CMOS-SPAD. Tale dispositivo prevede inoltre un TDC per aumentare la precisione temporale di dectection dei fotoni. Questa caratteristica, unita all’uso di una procedure di post-processing appositamente sviluppata e basata sull’algoritmo di Zhou-Bruk, ha permesso di raggiungere un bit rate finale pari a 300 Mbit/s. Per quanto riguarda i sistemi QKD, all’interno di un progetto di collaborazione tra l’Università di Padova, l’Agenzia Spaziale Italiana (ASI) insieme al Matera Laser Ranging Observatory (MLRO) e la Chinese Academy of Sciences (CAS) è stato sviluppato un software di gestione di un dispositivo TDC. Il progetto prevede la realizzazione di uno scambio di chiave crittografica quantistica tra il satellite cinese Micius e l’osservatorio di Matera. Il software è stato progettato per la gestione dell’intera acquisizione dati sincronizzata al tempo UTC. Inoltre è stato sviluppato anche un software per la gestione di componenti elettro-optomeccanici e elettro-ottici atti alla compensazione tempo variante delle variazioni angolari del fascio nel percorso ottico. Sempre all’interno di una collaborazione tra ASI e Università di Padova, è stato sviluppato un sistema completo di QKD free space per distanze nell’ordine di decine di chilometri. Lo sviluppo del sistema ha richiesto la progettazione di molteplici componenti. In questo lavoro viene descritta la parte della sorgente QKD e quindi della progettazione della scheda FPGA dedicata. Tale scheda ha il compito di generare gli impulsi elettrici per il controllo del laser per la produzione dei qubit e per il controllo dei modulatori di fase e di intensità elettro-ottici.

Alsayasneh, Maha. "On the identification of performance bottlenecks in multi-tier distributed systems". Thesis, Université Grenoble Alpes, 2020. http://www.theses.fr/2020GRALM009.
Texto completo da fonteToday's distributed systems are made of various software componentswith complex interactions and a large number of configurationsettings. Pinpointing the performance bottlenecks is generally a non-trivial task, which requires human expertise as well as trial anderror. Moreover, the same software stack may exhibit very differentbottlenecks depending on factors such as the underlying hardware, theapplication logic, the configuration settings, and the operatingconditions. This work aims to (i) investigate whether it is possibleto identify a set of key metrics that can be used as reliable andgeneral indicators of performance bottlenecks, (ii) identify thecharacteristics of these indicators, and (iii) build a tool that canautomatically and accurately determine if the system reaches itsmaximum capacity in terms of throughput.In this thesis, we present three contributions. First, we present ananalytical study of a large number of realistic configuration setupsof multi-tier distributed applications, more specifically focusing ondata processing pipelines. By analyzing a large number of metrics atthe hardware and at the software level, we identify the ones thatexhibit changes in their behavior at the point where the systemreaches its maximum capacity. We consider these metrics as reliableindicators of performance bottlenecks. Second, we leverage machinelearning techniques to build a tool that can automatically identifyperformance bottlenecks in the data processing pipeline. We considerdifferent machine learning methods, different selections of metrics,and different cases of generalization to new setups. Third, to assessthe validity of the results obtained considering the data processingpipeline for both the analytical and the learning-based approaches,the two approaches are applied to the case of a Web stack.From our research, we draw several conclusions. First, it is possibleto identify key metrics that act as reliable indicators of performancebottlenecks for a multi-tier distributed system. More precisely,identifying when the server has reached its maximum capacity can beidentified based on these reliable metrics. Contrary to the approachadopted by many existing works, our results show that a combination ofmetrics of different types is required to ensure reliableidentification of performance bottlenecks in a large number ofsetups. We also show that approaches based on machine learningtechniques to analyze metrics can identify performance bottlenecks ina multi-tier distributed system. The comparison of different modelsshows that the ones based on the reliable metrics identified by ouranalytical study are the ones that achieve the bestaccuracy. Furthermore, our extensive analysis shows the robustness ofthe obtained models that can generalize to new setups, to new numbersof clients, and to both new setups and new numbers ofclients. Extending the analysis to a Web stack confirmsthe main findings obtained through the study of the data processingpipeline. These results pave the way towards a general and accuratetool to identify performance bottlenecks in distributed systems

Texto completo da fonteDans cette thèse, nous nous intéressons à la problématique liée à la communication numérique sur courant porteur dans l’objectif de fournir une infrastructure de communication qui permet la surveillance et le contrôle de la distribution et de la consommation de l’énergie. Ce travail a été effectué dans le cadre du projet européen REMPLI (Real-time Energy Management via Power Line and Internet) et a produit la spécification REMPLI PLC (Power Line Communication). Pour fournir une meilleure performance de la communication et effectuer le transfert de données en temps réel, en utilisant les réseaux électriques de moyenne tension et de basse tension, les problèmes principaux qui sont le routage dynamique de paquets de données, la gestion de la qualité de service et la notification des événement en temps réel, ont été traités. Nous avons développé un protocole de routage efficace pour s’adapter au changement dynamique de topologie du réseau électrique. Les performances de REMPLI PLC sont évaluées en utilisant des approches de simulation couplée avec des approches analytiques. Il est prouvé que la majorité des besoins applicatifs peuvent être satisfaite par REMPLI PLC. Nous avons proposé et implanté un nouvel “ordonnançeur de traffic” fournissant différents niveaux de qualité de service pour les applications. Des variantes de protocole ALOHA ont été proposées et évaluées afin de vérifier que les propriétés temps réel requises sur les notifications d’événements sont respectées
