Smart Execution of Distributed Application by Balancing Resources in Mobile Devices
ALMA MATER STUDIORUM - UNIVERSITÀ DI BOLOGNA SCUOLA DI INGEGNERIA E ARCHITETTURA DISI INGEGNERIA INFORMATICA TESI DI LAUREA in Reti di Calcolatori M Smart execution of distributed application by balancing resources in mobile devices and cloud-based avatars CANDIDATO: RELATORE: Giacomo Gezzi Chiar.mo Prof. Ing. Antonio Corradi CORRELATORE: Chiar.mo Prof. Cristian Borcea Anno Accademico 2014/2015 Sessione III 2 Abstract L’obiettivo del progetto di tesi svolto e` quello di realizzare un servizio di livello middleware dedicato ai dispositivi mobili che sia in grado di fornire il supporto per l’offloading di codice verso una infrastruttura cloud. In particolare il progetto si concentra sulla migrazione di codice verso macchine virtuali dedicate al singolo utente. Il sistema operativo delle VMs e` lo stesso utilizzato dal device mobile. Come i precedenti lavori sul computation offloading, il progetto di tesi deve garantire migliori per- formance in termini di tempo di esecuzione e utilizzo della batteria del dispositivo. In particolare l’obiettivo piu` ampio e` quello di adattare il principio di computation offloading a un contesto di sistemi distribuiti mobili, miglio- rando non solo le performance del singolo device, ma l’esecuzione stessa dell’applicazione distribuita. Questo viene fatto tramite una gestione di- namica delle decisioni di offloading basata, non solo, sullo stato del de- vice, ma anche sulla volonta` e/o sullo stato degli altri utenti appartenenti allo stesso gruppo. Per esempio, un primo utente potrebbe influenzare le decisioni degli altri membri del gruppo specificando una determinata richiesta, come alta qualita` delle informazioni, risposta rapida o basata su altre informazioni di alto livello. -

It is written mostly in Java and can be used to develop applications in Java and, by means of various plug-ins, other programming languages including Ada, C, C++, COBOL, Perl, PHP, Python, Ruby (including Ruby on Rails framework), Scala, Clojure, and Scheme. The IDE is often called Eclipse ADT for Ada, Eclipse CDT for C/C++, Eclipse JDT for Java, and Eclipse PDT for PHP. The initial codebase originated from VisualAge.[2] In its default form it is meant for Java developers, consisting of the Java Development Tools (JDT). Users can extend its abilities by installing plug-ins written for the Eclipse software framework, such as development toolkits for other programming languages, and can write and contribute their own plug-in modules. Released under the terms of the Eclipse Public License, Eclipse is free and open source software. It was one of the first IDEs to run under GNU Classpath and it runs without issues under IcedTea. Eclipse (software) 2 Architecture Eclipse employs plug-ins in order to provide all of its functionality on top of (and including) the runtime system, in contrast to some other applications where functionality is typically hard coded. -

Design Pattern Implementation in Java and Aspectj
Design Pattern Implementation in Java and AspectJ Jan Hannemann Gregor Kiczales University of British Columbia University of British Columbia 201-2366 Main Mall 201-2366 Main Mall Vancouver B.C.

AspectJ implementations of the GoF design patterns show modularity improvements in 17 of 23 cases. These improvements When the GoF patterns were first identified, the sample are manifested in terms of better code locality, reusability, implementations were geared to the current state of the art in composability, and (un)pluggability. object-oriented languages. Other work [19, 22] has shown that implementation language affects pattern implementation, so it seems The degree of improvement in implementation modularity varies, natural to explore the effect of aspect-oriented programming with the greatest improvement coming when the pattern solution techniques [11] on the implementation of the GoF patterns. structure involves crosscutting of some form, including one object As an initial experiment we chose to develop and compare Java playing multiple roles, many objects playing one role, or an object [27] and AspectJ [25] implementations of the 23 GoF patterns. playing roles in multiple pattern instances. AspectJ is a seamless aspect-oriented extension to Java, which means that programming in AspectJ is effectively programming in Categories and Subject Descriptors Java plus aspects.

Weaving Eclipse Applications
Weaving Eclipse Applications Fabio Calefato, Filippo Lanubile, Mario Scalas, 1 Dipartimento di Informatica, Università di Bari, Italy {calefato, lanubile, scalas}@uniba.it Abstract. The Eclipse platform fully supports the ideas behind software components: in addition it also adds dynamic behavior allowing components to be added, replaced or removed at runtime without shutting the application down. While layered software architectures may be implemented by assembling components, the way these components are wired together differs. In this paper we present our solution of Dependecy Injection, which allows to build highly decoupled Eclipse applications in order to implement real separation of concerns by systemically applying Aspect Oriented Programming and the Model-View-Presenter pattern, a variant of the classic Model-View-Controller. Keywords: Eclipse, Aspect Oriented Programming, Dependency Injection. 1 Introduction The Dependency Inversion Principle [19] (DIP) states that (both high and low level) software parts should not depend on each other’s concrete implementation but, instead, be based on a common set of shared abstractions: one application of the DIP is the Dependency Injection, also called Inversion of Control (IoC) [11]. From an architectural perspective, DI allows to explicit the dependencies between software components and provides a way to break the normal coupling between a system under test and its dependencies during automated testing [25]. This is possible because the software is composed by aggregating simpler, loosely coupled objects that are more easily unit-testable [32]. Additionally, by separating the clients by their dependencies, we also make their code simpler because there is no need for them to search for their collaborators. -

Static Versus Dynamic Polymorphism When Implementing Variability in C++
Static Versus Dynamic Polymorphism When Implementing Variability in C++ by Samer AL Masri A thesis submitted in partial fulfillment of the requirements for the degree of Master of Science Department of Computing Science University of Alberta c Samer AL Masri, 2018 Abstract Software Product Line Engineering (SPLE) creates configurable platforms that can be used to efficiently produce similar, and yet different, product vari- ants. To implement SPLs, multiple variability implementation mechanisms have been suggested, including polymorphism. In this thesis, we talk about the trade-offs of using static versus dynamic polymorphism through a case study of IBM’s open-source Eclipse OMR project. Eclipse OMR is an open-source C++ framework for building robust lan- guage runtimes. To support the diverse languages and architectures targeted by the framework, OMR’s variability implementation uses a combination of build-system variability and static polymorphism. OMR developers now real- ize that their current static polymorphism implementation has its drawbacks and are considering using dynamic polymorphism instead. In order to study the trade-offs of using different kinds of polymorphism in OMR, it is crucial to collect function information and overload/override statistics about the current code base. Hence, we create OMRStatistics,a static analysis tool that collects such information about OMR’s source code. Using the information provided by OMRStatistics, OMR developers can make better design decisions on which variability extension points should be switched from static polymorphism to dynamic polymorphism. In addition, we report on our first hand experience of changing the poly- morphism used in OMR’s variability implementation mechanism from static to dynamic, the challenges we faced in the process, and how we overcame them. -
