In this work we present a portal to the EGEE user that allows to submit widely used scientific softwares as jobs to EGEE. The main target of this interface is to hide from the end user low-level...

Current applications involving satellite data need huge computational power and storage capacities. Grid computing technologies that have evolved in the last decade promise to make feasible the creation of an environment, for these kinds of applications, which can handle hundreds of distributed databases, heterogeneous computing resources, and simultaneous users. In this context the recent...

GRIDSEED provides a simple tool to setup up a portable fully fledged gLite grid infrastructure based on virtual machines. It exploits the concept of “grid in a box” providing a self-containing grid that could be easily deployed in any existing infrastructure for training and dissemination purposes. In this work we present a recent effort to include ARC middleware in the original GRIDSEED...

The XtreemOS operating system provides for Grids what a traditional operating system offers for a single computer: abstraction from the hardware and secure resource sharing between different users. When a user runs an application on XtreemOS, the operating system automatically finds all resources necessary for the execution, configures user’s credentials on the selected resources and starts...

We present how idle disk space available at desktops and worker nodes in computing elements can be used to implement the file system back-end of a gLite storage element. We developed the BeeFS to federate the distributed disks. Like some special-purpose file systems (eg. GFS), it uses a hybrid architecture that follows a client-server approach for serving metadata and manage file replicas, and...

Computer programs which can provide insight into such biological recognition processes have significant potential to contribute to biomedical research if the results of the simulation can prove consistent with the outcome of conventional wet laboratory experiments. In order to validate these...

Most workflow management systems in Grid environments provide a push-oriented job distribution strategy, where jobs are explicitly delegated to resources. In those scenarios dedicated resources execute jobs according to the request of a workflow engine or Grid wide scheduler. This approach has various limitations, particularly if human interactions should be integrated in workflows. To support...

First SAGA application integration tests within EGEE...

An MPI Working Group has been setup with the goal to investigate why so few Grid sites support MPI and why so few people are using it. The Working Group has come up with a recommendation document in which the current issues with MPI on the Grid are analyzed, the reasons for non-usage are investigated and the plans for future expensions are summarized.

Despite numerous benefits, many Web Services (WS) face problems with respect to data transport, either because SOAP doesn't offer a scalable way of transporting large data-sets or because orchestration workflows (WF) don’t move data around efficiently. In this paper we address both problems with the development of the ProxyWS. This is a WS utilizing protocols offered by the Virtual Resource...

PROOF on Demand (PoD) is a set of utilities, which allows starting a PROOF cluster at a user request, on any resource management system. It provides a plug-in based system, to use different job submission frontends, such as LSF or gLite WMS. PoD is fully automated, and no special knowledge is required to start to use it.

One typical problem to be solved by fusion codes, which is suitable for grid and parallel computing, is the parameter scan. There are several codes whose main purpose is to get results for wide parameter range. So it makes sense to build a tool that allows one to perform this parameter scan in an automated way. We have build and used a new tool suitable for solving this kind of problems:...

Most existing workflow systems are tightly integrated with middleware, which limit wide scale adoption and may limit efficient execution of workflows. Whereas the use of SAGA enables the use of multiple heterogeneous resources, there exists an initial but somewhat limited support for workflows using the SAGA specification. Thus to reconcile the advantages of the SAGA paradigm with broad usage...

These applications are part of an ongoing project...
