A comparative evaluation of transparent scaling techniques for dynamic content web servers

We study several transparent techniques for scaling dynamic content web sites, and we evaluate their relative impact when used in combination. Full transparency implies strong data consistency as perceived by the user, no modi- fications to existing dynami ...

Range queries in trie-structured overlays

Karl Aberer, Manfred Hauswirth, Anwitaman Datta, Roman Schmidt, Renault John Lecoultre

Among the open problems in P2P systems, support for non-trivial search predicates, standardized query languages, distributed query processing, query load balancing, and quality of query results have been identified as some of the most relevant issues. This ...

MobiRoute: Routing towards a Mobile Sink for Improving Lifetime in Sensor Networks

Jean-Pierre Hubaux, Matthias Grossglauser, Jun Luo, Jacques Panchard

Improving network lifetime is an important issue involved in every aspect of the design and deployment of wireless sensor networks. There is a recent research trend of studying the application of a mobile sink to transport (rather than let the sensor nodes ...

Parallelization and scheduling of data intensive particle physics analysis jobs on clusters of PCs

Roger Hersch, Sébastien Ponce

Scheduling policies are proposed for parallelizing data intensive particle physics analysis applications on computer clusters. Particle physics analysis jobs require the analysis of tens of thousands of particle collision events, each event requiring typic ...

FUSE: Lightweight Guaranteed Distributed Failure Notification

Dejan Kostic

FUSE is a lightweight failure notification service for building distributed systems. Distributed systems built with FUSE are guaranteed that failure notifications never fail. Whenever a failure notification is triggered, all live members of the FUSE group ...

The Quest for Balancing Peer Load in Structured Peer-to-Peer Systems

Karl Aberer, Manfred Hauswirth, Anwitaman Datta

Structured peer-to-peer (P2P) systems are considered as the next generation application backbone on the Internet. An important problem of these systems is load balancing in the presence of non-uniform data distributions. In this paper we propose a complete ...

Load sharing for multiprocessor network nodes

This thesis discusses techniques for sharing the processing load among multiple processing units within systems that act as nodes in a data communications network. Load-sharing techniques have been explored in the field of computer science for many years a ...

Evaluating the performance of distributed agreement algorithms

Nowadays, networked computers are present in most aspects of everyday life. Moreover, essential parts of society come to depend on distributed systems formed of networked computers, thus making such systems secure and fault tolerant is a top priority. If t ...

Network topology aware scheduling of collective communications

Roger Hersch, Emin Gabrielyan

A method is proposed for the optimal scheduling of collective data exchanges relying on the knowledge of the underlying network topology. The concept of liquid schedules is introduced. Liquid schedules ensure the maximal utilization of a network's bottlene ...
