Just-in-time performance without warm-up

Scala has been developed as a language that deeply integrates with the Java ecosystem. It offers seamless interoperability with existing Java libraries. Since the Scala compiler targets Java bytecode, Scala programs have access to high-performance runtimes ...

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 ...

A Methodology for Profiling and Partitioning Stream Programs on Many-core Architectures

Marco Mattavelli, Malgorzata Maria Michalska, Jani Boutellier

Maximizing the data throughput is a very common implementation objective for several streaming applications. Such task is particularly challenging for implementations based on many-core and multi-core target platforms because, in general, it implies tackli ...

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 ...

Methods to explore design space for MPEG RMC codec specifications

Marco Mattavelli, Simone Casale Brunet, Endri Bezati, Ghislain Roquier, Richard Thavot, Abdallah Alaaeldin Abdelaziz Elguindy

The recent MPEG Reconfigurable Media Coding (RMC) standard aims at defining media processing specifications (e.g. video codecs) in a form that abstracts from the implementation platform, but at the same time is an appropriate starting point for implementat ...

Isolated Actors for Race-Free Concurrent Programming

Philipp Haller

Message-based concurrency using actors has the potential to scale from multicore processors to distributed systems. However, several challenges remain until actor-based programming can be applied on a large scale. First, actor implementations must be effic ...

Compiling structural types on the JVM: a comparison of reflective and generative techniques from Scala's perspective

Martin Odersky, Gilles Dubochet

This article describes Scala's compilation technique of structural types for the JVM. The technique uses Java reflection and polymorphic inline caches. Performance measurements of this technique are presented and analysed. Further measurements compare Scal ...

Deadlock Immunity: Enabling Systems To Defend Against Deadlocks

George Candea, Cristian Zamfir, Horatiu Jula, Daniel Tralamazza

Deadlock immunity is a property by which programs, once afflicted by a given deadlock, develop resistance against future occurrences of that and similar deadlocks. We describe a technique that enables programs to automatically gain such immunity without as ...

Program Transformations for Light-Weight CPU Accounting and Control in the Java Virtual Machine - A Systematic Review

This article constitutes a thorough presentation of an original scheme for portable CPU accounting and control in Java, which is based on program transformation techniques at the bytecode level and can be used with every standard Java Virtual Machine. In o ...

Sharing of probabilistically correlated data in peer-to-peer networks

Roman Schmidt

The impact of Peer-to-Peer (P2P) networks on the Internet landscape is undisputed. It has led to a series of new applications, e.g., as part of the so-called Web 2.0. The shift from the classical client-server based paradigm of the Internet, with a clear d ...

Reflexes: programming abstractions for highly responsive computing in Java

Jesper Honig Spring

Achieving sub-millisecond response times in a managed language environment such as Java introduces significant implementation challenges. The Achilles' heel of Java is its reliance on automatic memory management for reclaiming dead objects. Typically, the ...

The Marr Wavelet Pyramid and Multiscale Directional Image Analysis

Michaël Unser, Dimitri Nestor Alice Van De Ville, Daniel Sage, Katarina Balac

The “Marr wavelet pyramid” is a wavelet decomposition that implements a multiscale version of the complex gradient-Laplace operator. It is closely linked to a multiresolution analysis of

L _{ 2 }

(\mathbb{R} ^{ 2 }

) and it has a fast filterbank im ...

Platform-independent profiling in a virtual execution environment

Philippe Moret

Virtual execution environments, such as the Java virtual machine, promote platform-independent software development. However, when it comes to analyzing algorithm complexity and performance bottlenecks, available tools focus on platform-specific metrics, s ...

Algorithms for Interface Synthesis

Vasu Singh, Dirk Thilo Beyer

A temporal interface for a software component is a ﬁnite automaton that speciﬁes the legal sequences of calls to functions that are provided by the component. We compare and evaluate three different algorithms for automatically extracting temporal interfac ...

Reengineering Standard Java Runtime Systems through Dynamic Bytecode Instrumentation

Philippe Moret

Java bytecode instrumentation is a widely used technique, especially for profiling purposes. In order to ensure the instrumentation of all classes in the system, including dynamically generated or downloaded code, instrumentation has to be performed at run ...

Reflexes: Abstractions for Highly Responsive Systems

Rachid Guerraoui, Jesper Honig Spring

Commercial Java virtual machines are designed to maximize the performance of applications at the expense of predictability. High throughput garbage collection algorithms, for example, can introduce pauses of 100 milliseconds or more. We are interested in s ...

A Snake-Based Approach to Accurate Determination of Both Contact Points and Contact Angles

Patrik Willi Hoffmann, Daniel Sage, Laura Barbieri, Gerit Kulik

We present a new method based on B-spline snakes (active contours) for measuring high-accuracy contact angles. In this approach, we avoid making physical assumptions by defining the contour of the drop as a versatile B-spline curve. When useful, we extend ...

Queryll: Java Database Queries through Bytecode Rewriting

Willy Zwaenepoel, Christopher Ming-Yee Iu

When interfacing Java with other systems such as databases, programmers must often program in special interface languages like SQL. Code written in these languages often needs to be embedded in strings where they cannot be error-checked at compile-time, or ...

Exact and Portable Profiling for the JVM Using Bytecode Instruction Counting

This paper presents a novel profiling approach, which is entirely based on program transformation techniques in order to enable exact profiling, preserving complete call stacks, method invocation counters, and bytecode instruction counters. We exploit the ...

Automatic Tracking of Individual Fluorescence Particles: Application to the Study of Chromosome Dynamics

Michaël Unser, Daniel Sage

We present a new, robust, computational procedure for tracking fluorescent markers in time-lapse microscopy. The algorithm is optimized for finding the time-trajectory of single particles in very noisy dynamic (two- or three-dimensional) image sequences. I ...
