Prof. Ludek Matyska (CESNET, z.s.p.o.)02/03/2006, 14:00Workload management and WorkflowsOral contributionLogging and Bookkeeping (LB) service is responsible for keeping track of jobs within a complex Grid environment. Without such a service, users are unable to find out what happened with their lost jobs and Grid administrators are not able to improve the infrastructure. The LB service developed within the EGEE project provides a distributed scalable solution able to deal with hundreds...Go to contribution page

Francesco Giacomini (Istituto Nazionale di Fisica Nucleare (INFN))02/03/2006, 14:30Workload management and WorkflowsOral contributionThe Workload Management System (WMS) is a collection of components providing a service responsible for the distribution and management of tasks across resources available on a Grid, in such a way that applications are conveniently, efficiently and effectively executed. The main purpose of the WMS as a whole is then to accept a request of execution of a job from a client, find...Go to contribution page

Giuseppe Codispoti (Universita di Bologna)02/03/2006, 15:00Workload management and WorkflowsOral contributionBOSS (Batch Object Submission System) has been developed in the context of the CMS experiment to provide logging and bookkeeping and real-time monitoring of jobs submitted to a local farm or a grid system. The information is persistently stored in a relational database (right now MySQL or SQLite) for further processing. In this way the information that was available in the log file in a...Go to contribution page

Tristan Glatard (CNRS)02/03/2006, 15:30Workload management and WorkflowsOral contribution** Managing data-intensive application workflows Many data analysis procedures implemented on grids are not only based on a single processing algorithm but rather assembled from a set of basic tools dedicated to process the data, model it, extract quantitative information, analyze results, etc. Given that interoperable algorithms packed in software components with a standardized...Go to contribution page

Ladislav Hluchy (Institute of Informatics, Slovakia)02/03/2006, 16:30Workload management and WorkflowsOral contributionWe present an IST project of the 6th Framework Programme, aimed towards intelligent grid middleware and workflow construction. The project's acronym K-Wf Grid stands for “Knowledge-based Workflow System for Grid Applications”. The project itself employs ontologies, artificial reasoning, Petri nets and modern service-oriented architectures in order to simplify the use of grid...Go to contribution page

Mr Andrea Caltroni (INFN)02/03/2006, 17:00Workload management and WorkflowsOral contributionSharing computing and storage resources among multiple Virtual Organizations which group people from different institutions often spanning many countries, requires a comprehensive policy management framework. This paper introduces G-PBox, a tool for the management of policies which integrates with other VO-based tools like VOMS, an attribute authority and DGAS an accounting system, to...Go to contribution page

Dr Jean-Pierre Prost (IBM Montpellier)02/03/2006, 17:30Workload management and WorkflowsOral contribution"Workload virtualization is made of several disciplines: job/workflow scheduling, workload management, and provisioning. Much work has been spent so far on these various components in isolation. A better synergistic integration of these components allowing their interoperability towards an optimized resource allocation in order to satisfy user specified service level objectives is...Go to contribution page
