Extensible Transactional Memory Testbed

Vincent Gramoli, Pascal Felber

Transactional Memory (TM) is a promising abstraction as it hides all synchronization complexities from the programmers of concurrent applications. More particularly the TM paradigm operated a complexity shift from the application programming to the TM prog ...

Studying Application–Library Interaction and Behavior with LibTrac

George Candea, Paul Dan Marinescu, Eric Bisolfati

The boundary between programs and libraries is an appealing location for injecting faults during testing: the cost of doing so is low, and one can emulate a wide range of errors. Several tools exist, but using them faces the challenge of deciding exactly w ...

PathScore-Relevance: A Metric for Improving Test Quality

George Candea, Silviu Andrica

Reliability of today's software systems hinges on developers writing test cases that exercise as much of a program as possible. Writing and running such tests is inevitably subject to a time budget. This paper addresses the question of how to maximize qual ...

Selective Symbolic Execution

George Candea, Cristian Zamfir, Vitaly Chipounov

Symbolic execution is a powerful technique for analyzing program behavior, finding bugs, and generating tests, but suffers from severely limited scalability: the largest programs that can be symbolically executed today are on the order of thousands of line ...

Real-Time ASR from Meetings

Philip Neil Garner, John David Scott Dines, Danil Korchagin, Le Zhang

The AMI(DA) system is a meeting room speech recognition system that has been developed and evaluated in the context of the NIST Rich Text (RT) evaluations. Recently, the ``Distant Access'' requirements of the AMIDA project have necessitated that the system ...

Almost-Invariants: From Bugs in Distributed Systems to Invariants

Dejan Kostic, Marco Canini, Maysam Yabandeh, Abhishek Anand

It is notoriously hard to develop dependable distributed systems. This is partly due to the difficulties in foreseeing various corner cases and failure scenarios while implementing a system that will be deployed over an asynchronous network. In contrast, r ...

LFI: A Practical and General Library-Level Fault Injector

George Candea, Paul Dan Marinescu

Fault injection, a critical aspect of testing robust systems, is often overlooked in the development of general-purpose software. We believe this is due to the absence of easy-to-use tools and to the extensive manual labor required to perform fault injecti ...

PyNN: a common interface for neuronal network simulators

Eilif Benjamin Muller

Computational neuroscience has produced a diversity of software for simulations of networks of spiking neurons, with both negative and positive consequences. On the one hand, each simulator uses its own programming or configuration language, leading to con ...

Concrete syntax definition for modeling languages

Frédéric Fondement

Model Driven Engineering (MDE) promotes the use of models as primary artefacts of a software development process, as an attempt to handle complexity through abstraction, e.g. to cope with the evolution of execution platforms. MDE follows a stepwise approac ...
