The Handling of Graphs on PC Clusters: A Coarse Grained Approach

We study the relationship between the design and analysis of graph algorithms in the coarsed grained parallel models and the behavior of the resulting code on clusters. We conclude that the coarse grained multicomputer model (CGM) is well suited to design competitive algorithms, and that it is thereby now possible to aim to develop portable, predictable and efficient parallel code for graph pro...

Interactive Analysis of Large Distributed Systems with Topology-based Visualization

The performance of parallel and distributed applications is highly dependent on the characteristics of the execution environment. In such environments, the network topology and characteristics directly impact data locality and movements as well as contention, which are key phenomena to understand the behavior of such applications and possibly improve it. Unfortunately few visualization availabl...

Mastering Model Driven Engineering complexity by interactive visualization

Model Driven Engineering (MDE) can play an important role for the design of applications in many domains. Its principles that are separations of concerns, capitalisation of knowledge thanks to models, meta models, and transformations, are well accepted today. Then the approach becomes a good candidate for scaling up to more complex applications. However the use of model driven engineering puts ...

Contribution à la conception à base de composants logiciels d'applications scientifiques parallèles. (Contribution to the design of scientific parallel applications based on software components)

ion des ressources Afin de faciliter le portage de l’application, le modèle de programmation utilisé doit permettre d’abstraire la conception d’applications des ressources visées. En effet, chaque application doit être optimisée en fonction des ressources d’exécution. Il est donc nécessaire d’adapter certaines parties de l’application. Les modèles de composants logiciels doivent permettre d’exp...
