ProtoPeer: from Simulation to Live Deployment in One Step

Karl Aberer, Wojciech Galuba, Zoran Despotovic

We present ProtoPeer, a peer-to-peer systems prototyping toolkit that allows for switching between the event driven simulation and live network deployment without changing any of the application code. ProtoPeer exports a set of APIs for message passing, me ...

A simulator for adaptive parallel applications

Roger Hersch, Sebastian Gerlach

Dynamically allocating computing nodes to parallel applications is a promising technique for improving the utilization of cluster resources. Detailed simulations can help identify allocation strategies and problem decomposition parameters that increase the ...

Can a Helmholtz solver run on a cluster?

Marc Anthony David Habisreutinger, Emmanuel Leriche, Vincent Keller

Our vectorized Helmholtz solver runs at 85% efficiency on a NEC SX-5. The most time-consuming parts have been ported on SMP, NUMA, and cluster architectures. It is shown that an OpenMP version can deliver similar performance when running it on a 16 process ...

Parallel network simulations with NEURON

Henry Markram

The NEURON simulation environment has been extended to support parallel network simulations. Each processor integrates the equations for its subnet over an interval equal to the minimum (interprocessor) presynaptic spike generation to postsynaptic spike de ...

A simulator for parallel applications with dynamically varying compute node allocation

Roger Hersch, Sebastian Gerlach

Dynamically allocating computing nodes to parallel applications is a promising technique for improving the utilization of cluster resources. We introduce the concept of dynamic efficiency which expresses the resource utilization efficiency as a function of ...

Issues in petabyte data indexing, retrieval and analysis

Sébastien Ponce

We propose several methods for speeding up the processing of particle physics data on clusters of PCs. We present a new way of indexing and retrieving data in a high dimensional space by making use of two levels of catalogues enabling an efficient data pre ...

JOpera: Autonomic Service Orchestration

Thomas Heinis

The increasing interest in new software engineering technologies for application integration such as Service Oriented Computing and Service Orchestration has resulted in a proliferation of workflow management systems as the underlying representation and ex ...

High sensitivity absorption measurement of small metal clusters embedded in an argon matrix

Fabien Conus

We describe a new UV-Vis absorption setup designed to measure with improved sensitivity the absorption spectra of size-selected small metal clusters embedded in rare gas matrices. We aim at studying the electronic structure of clusters of different materia ...

Performance Evaluation of Barrier Techniques for Distributed Tracing Garbage Collector

David Atienza Alonso

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 ...

Fault-tolerant parallel applications with dynamic parallel schedules

Roger Hersch, Sebastian Gerlach

Commodity computer clusters are often composed of hundreds of computing nodes. These generally off-the-shelf systems are not designed for high reliability. Node failures therefore drive the MTBF of such clusters to unacceptable levels. The software framewo ...
