Title: From Performance Modelling to Dynamic Optimization of Concurrent Applications in the Era of Multi-core and Cloud Architectures
Abstract: Over the past fifteen years, there has been a massive shift towards parallel and distributed computing architectures, pushed by the proliferation of multi-core systems and cloud computing platforms. Scaling the computing power offered by these architectures requires that applications be concurrent and/or distributed. Also, applications should be "elastic" to take advantage of on-demand resource provisioning offered by the cloud. On the other hand, the analysis and the optimization of the non-functional requirements, like performance, availability and energy efficiency, has become more complex. This is due to the greater complexity and dynamism of these architectures, and to the need for synchronization and communication between concurrent threads, processes, and computer nodes of the applications.
In this seminar, I present my research activity, spanning from models for quantifying and predicting fundamental non-functional metrics of the applications to model-based and heuristic techniques for the dynamic optimization. I will enter into the details of analytical modeling approaches, machine learning-based methods and simulation tools that can help to identify and understand the quantitative relations between system features and non-functional metrics. Also, I will show how they can support model-driven optimization processes. Finally, I will discuss about hybrid techniques, and techniques for the performance optimization under power or availability constraints.

Short Bio. Pierangelo Di Sanzo received a M.S. degree and a Ph.D. degree in Computer Engineering from Sapienza University of Rome. Currently, he is a researcher at DISIM, University of L'Aquila. Previously, he worked as a researcher with various research institutes, as CINI, CINFAI and ISSNOVA, and as a postdoctoral researcher at DIAG, Sapienza University of Rome. Also, he was a consultant for public and private entities, like Poste Itaiane, Selex-Finmeccanica Group, the Italian Ministry of Justice and TDGroup/Aruba Consortium, and was a founder of a university spin-off. His research interests lie in the area of performance modelling, evaluation and optimization of non-functional requirements of computer systems and applications, with special focus on transactional systems, concurrent and parallel applications, distributed and cloud computing platforms.
ANNUNCIO URGENTE DIDATTICA II SEMESTRE
Preso atto del perdurare di una situazione epidemiologica critica e considerato che la mobilità degli studenti universitari può rappresentare un maggior fattore di diffusione dell’infezione, l’Università degli Studi dell’Aquila, aggiornando disposizioni precedenti, ha deciso di adottare la didattica a distanza sino al giorno 6 aprile 2021, riservandosi di rivedere tale modalità in relazione all’evoluzione della situazione sanitaria o ad interventi delle autorità competenti a livello regionale o nazionale. Tutte le norme e le prescrizioni da rispettare sono consultabili al seguente indirizzo: https://www.univaq.it/include/utilities/blob.php?item=allegato&table=avviso&id=15250.
Ricordiamo a tutte le studentesse e a tutti gli studenti che tutta la didattica sarà fruibile in modalità sincrona (ovvero mediante streaming live) sui nostri canali Teams, secondo gli orari consultabili cliccando sul seguente pulsante:
IMPORTANT ANNOUNCEMENT TEACHING II SEMESTER
Noting the persistence of a critical epidemiological situation and the fact that the mobility of university students can be a greater spread of infection factor, the University of L'Aquila, updating previous provisions, decided to adopt the distance learning up as of 6 April 2021, reserving the right to review this method in relation to the evolution of the health situation or interventions by the competent authorities at regional or national level. All the rules and regulations to be respected can be consulted at the following address: https://www.univaq.it/include/utilities/blob.php?item=allegato&table=avviso&id=15250.
We remind the students that all the teaching will be available in synchronous mode (or by live streaming) on our channels teams and the times are consulted by clicking on the following button:
