A wide variety of applications, particularly in High Performance Computing, relies on distributed environments to process and analyse large amounts of data. New infrastruc-tures have emerged to support the execution of such computations, most of them involve distributed computing, parallelizing the computing process among the nodes of a large distributed(More)
Among existing grid middleware approaches, one simple, powerful, and flexible approach consists of using servers available in different administrative domains through the classic client-server or Remote Procedure Call (RPC) paradigm. Network Enabled Servers (NES) implement this model also called GridRPC. Clients submit computation requests to a scheduler(More)
A self-stabilizing asynchronous distributed algorithm is given for constructing a k-dominating set, and hence a k-clustering, of a connected network of processes with unique IDs and weighted edges. The algorithm is comparison-based, takes O(nk) time, and uses O(log n + log k) space per process, where n is the size of the network. It is known that finding a(More)

Large problems ranging from numerical simulation can now be solved through the Internet using grid middleware. This paper describes the different steps involved to make available a service in the DIET grid middleware. The cosmological RAMSES application is taken as an example to detail the implementation. Furthermore, several results are given in order to(More)
It is nowadays common to use a grid middleware to access distributed resources in order to solve large problems. Many middleware can be found in the literature. Whereas they all rely on the use of resource brokers (also sometimes called agents) to schedule jobs, and servers to execute them, they do not share the same structure. Many rely on a simple design,(More)
Accessing the power of distributed resources can nowadays easily be done using a middleware based on a client/server approach. Several architectures exist for those middlewares. The most scalable ones rely on a hierarchical design. Determining the best shape for the hierarchy, the one giving the best throughput of services, is not an easy task. We first(More)

The E-Biothon platform [1] is an experimental Cloud platform to help speed up and advance research in biology, health and environment. It is based on a Blue Gene/P system and a web portal that allow members of the bioinformatics community to easily launch their scientific applications. We describe in this paper the technical capacities of the platform, the(More)
