Diet: A Scalable Toolbox to Build Network Enabled Servers on the Grid

Abstract

Among existing grid middleware approaches, one simple, powerful, and flexible approach consists of using servers available in different administrative domains through the classical client-server or Remote Procedure Call (RPC) paradigm. Network Enabled Servers implement this model also called GridRPC. Clients submit computation requests to a scheduler whose goal is to find a server available on the grid. The aim of this paper is to give an overview of a middleware developed in the GRAAL team called DIET 1 . DIET (Distributed Interactive Engineering Toolbox) is a hierarchical set of components used for the development of applications based on computational servers on the grid. RésuméParmi les intergiciels de grilles existants, une approche simple, flexible et performante consisteà utiliser des serveurs disponibles dans des domaines administratifs différentsà travers le paradigme classique de l'appel de procédureà distance (RPC). Les environnements de ce type, connus sous le terme de Network Enabled Servers, implémentent ce modèle appelé GridRPC. Des clients soumettent des requêtes de calculà un ordonnanceur dont le but consisteà trouver un serveur disponible sur la grille. Le but de cet article est de donner un tour d'horizon d'un intergiciel développé dans le projet GRAAL appelé DIET 2 . DIET (Distributed Interactive Engineering Toolbox) est un ensemble hiérarchique de composants utilisés pour le développement d'applications basées sur des serveurs de calcul sur la grille.

SmartGridRPC: The new RPC model for high performance Grid computing

“…Other possible implementations could include the Network Weather Service [8], FAST (DIET) [4], the MDS directories (Globus, Ninf) [3], and the Historical Trace Manager (GridSolve) [9]. Implementing these performance models under the SmartGridRPC model would allow for collective discovery of the task graph for a group tasks and the discovery of the performance model of the fully or partially connected network.…”

“…A number of Grid middleware systems are GridRPC compliant, including GridSolve [2], Ninf-G [3], and DIET [4].…”

Diet: New Developments and Recent Results

“…GoDIET for diverse grid environments. Key goals of GoDIET included portability, the ability to integrate GoDIET in a graphically-based user tool for DIET management, and the ability to communicate in CORBA with LogService [14]. GoDIET automatically generates configuration files for each DIET element while taking into account user configuration preferences and the hierarchy defined by the user, launches complimentary services (such as a name service and logging services), provides an ordered launch of components based on dependencies defined by the hierarchy, and provides remote cleanup of launched processes when the deployed platform is to be destroyed.…”

Solving Large Sparse Linear Systems Efficiently on Grid Computers Using an Asynchronous Iterative Method as a Preconditioner

“…The GridRPC Application Programming Interface (API) is defined within the Global Grid Forum [11]. Other projects that implement the GridRPC API are DIET [12], NetSolve [13], Ninf-G [14], and OmniRPC [15].…”
