Immediate Tracing

Valentin Aebi

This semester project report describes a prototype tracing tool that records the behavior of a Java program during its execution. It explains the two methods that were attempted to implement the tool, one using the Java debug interface, which gave poor res ...

Optimizing Java on Truffle

Ekaterina Goltsova

Java on Truffle is an early-stage implementation of a Java Virtual Machine in Java. So far its development has focused on compatibility and functionality, not addressing performance in a systematic way. This thesis presents a series of experiments on Java ...

Too Quiet in the Library: An Empirical Study of Security Updates in Android Apps' Native Code

Mathias Josef Payer

Android apps include third-party native libraries to increase performance and to reuse functionality. Native code is directly executed from apps through the Java Native Interface or the Android Native Development Kit. Android developers add precompiled nat ...

Cross-Platform Language Design

Sébastien Jean R Doeraene

Programming languages are increasingly compiled to multiple runtimes, each featuring their own rich structures such as their object model. Furthermore, they need to interact with other languages targeting said runtimes. A language targeting only one runtim ...

Correct Transformation of High-Level Models into Time-Triggered Implementations

Simon Bliudze

A number of component-based frameworks have been proposed to tackle the complexity of the design of concurrent software and systems and, in particular, to allow modelling and simulation of critical embedded applications. Such design frameworks usually prov ...

2016

Just-in-time (JIT) compilation of running programs provides more optimization opportunities than offline compilation. Modern JIT compilers, such as those in virtual machines like Oracle's HotSpot for Java or Google's V8 for JavaScript, rely on dynamic prof ...

Architecture Internalisation in BIP

Joseph Sifakis, Simon Bliudze

We consider two approaches for building component-based systems, which we call respectively architecture-based and architecture-agnostic. The former consists in describing coordination constraints in a purely declarative manner through parameterizable glue ...

ACM2014

Architectures allow shifting the focus of developers from low-level code to high-level structures ensuring coordination in component-based systems. If the architecture description language is expressive enough, it is possible to describe architectures in a ...

DeepDive: Transparently Identifying and Managing Performance Interference in Virtualized Environments

Dejan Novakovic, Dejan Kostic, Nedeljko Vasic, Ricardo Bianchini, Stanko Novakovic

Cloud computing in general, and Infrastructure-as-a-Service (IaaS) in particular, are becoming ever more popular. Unfortunately, performance interference (and the resulting unpredictability in the delivered performance) across virtual machines (VMs) co-loc ...

2013

Nowadays, Java is used in all types of embedded devices. For these memory-constrained systems, the automatic dynamicmemorymanager (Garbage Collector or GC) has been always a key factor in terms of the Java Virtual Machine (JVM) performance. Moreover, in cu ...
