This paper studies implementations of concurrent objects that exploit the absence of step contention. These implementations use only reads and writes when a process is running solo. The other processes might be busy with other objects, swapped-out, failed, ...
Many important synchronization problems in distributed computing are impossible to solve (in a fault-tolerant manner) in purely asynchronous systems, where message transmission delays and relative processor speeds are unbounded. It is then natural to seek ...
Currently, software engineering is becoming even more complex due to distributed computing. In this new context, portability is one of the key issues and hence a cluster-aware Java Virtual Machine (JVM) that can transparently execute Java applications in a ...
Superscalar out-of-order microarchitectures can be modified to support redundant execution of a program as two concurrent threads for soft-error detection. However, the extra workload from redundant execution incurs a performance penalty due to increased c ...
This paper presents a simple framework unifying a family of consensus algorithms that can tolerate process crash failures and asynchronous periods of the network, also called indulgent consensus algorithms. Key to the framework is a new abstraction we intr ...
This paper presents a computing model for resource-limited mobile devices. The originality of the model lies in the integration of a strongly-typed event-based communication paradigm with abstractions for frugal control, assuming a small footprint runtime. ...
The main objective of the Intelligent GRID Scheduling System (ISS) project is to provide a middleware infrastructure allowing a good positioning and scheduling of real life applications in a computational GRID. According to data collected on the machines i ...
Text categorization is intrinsically a supervised learning task, which aims at relating a given text document to one or more predefined categories. Unfortunately, labeling such databases of documents is a painful task. We present in this paper a method tha ...
In this paper we address the problem of encoding complex concurrency control in reconfigurable systems. Such systems can be often reconfigured, either statically, or dynamically, in order to adapt to new requirements and a changing environment. We therefor ...
We propose a novel detection method for non-coherent synchronization (signal acquisition) in multi-access UWB impulse radio (IR) networks. It is designed to solve the IUI (Inter-User Interference) that occurs in some ad-hoc networks where concurrent transm ...
