A Distributed and Heuristic Policy-based Management Architecture for Large-Scale GridsMagaña Perdomo, Edgar 30 May 2008 (has links)
The aim of this thesis is to design and implement a new Grid Resource Management methodology, where non-massive resources owners would be able to share their resources and integrate human collaboration across multiple domains regardless of network technology, operative platform or administrative domain.This thesis proposes a distributed and heuristic policy-based resource management architecture for large-scale Grids. The resource management architecture proposed herein is composed of four main building blocs: services management, resource discovery and monitoring, resource scheduling and jobs allocation and activation. The Grid Services Management (GSM) and Jobs Allocation and Activation (JAA) are supported by means of a Policy-based Grid Resource Management Architecture (PbGRMA). This architecture is able to identify service needs arising from diverse sources during the deployment and management of Grid Services, such as requirements demanded by customers, applications and network conditions. Afterwards, the PbGRMA merges these requirements into deployment policies for the corresponding Grid Services. The Grid Resource Discovery and Monitoring (GRDM) is supported by the introduction of the SNMP-based Balanced Load Monitoring Agents for Resource Scheduling (SBLOMARS), in which network and computational resources are monitored by distributed agents. This allows for a flexible, heterogeneous and scalable monitoring system. The Grid Resource Scheduling (GRS) is based on the Balanced Load Multi-Constrained Resource Scheduler (BLOMERS). This heuristic scheduler represents an alternate way of solving the inherent NP-hard problem for resource scheduling in large-scale distributed networks by means of the implementation of a Genetic Algorithm.Finally, based on the outcome of both the GRDM and GRS, the PbGRMA allocates the corresponding Grid Services by means of its interfaces with Globus ToolKit Middleware and Unix-based CLI commands along of any large-scale Grid Infrastructure. The synergy obtained by these components allows Grid administrators to exploit the available resources with predetermined levels of Quality of Service (QoS), reducing computational costs and makespan in resource scheduling while ensuring that the resource load is balanced throughout the Grid. The makespan of a schedule is the time required for all jobs to be processed when no one job could be interrupted during its execution and each node can perform at most one operation at any time.This new approach has been successfully tested in a real large-scale scenario such as Grid5000. The results presented along this Thesis show that our general solution is a reliable, flexible and scalable architecture to deploy and manage Grid Services in large-scale Grid Infrastructures. Moreover, the substitution of the heuristic algorithm approach used into the Grid Resource Scheduling (GRS) phase by other non-heuristics selection algorithms could make our solution useful in smaller Grid Infrastructures.

Previous issue date: 2016-02-23 / A presente pesquisa foi desenvolvida no âmbito do Mestrado do Programa de PósGraduação Profissional em Gestão e Avaliação da Educação Pública. No ano de 2011, a Secretaria de Estado de Educação do Rio de Janeiro adotou a Gestão Integrada da Escola (GIDE) como sistema de gestão, com foco em resultados. Esta dissertação teve como objetivo analisar as ações da rotina do Comitê GIDE, responsável por monitorar a implantação da política pública da rede estadual do Rio de Janeiro. Para implantar a GIDE nas escolas, foram selecionados Agentes de Acompanhamento da Gestão Escolar (AAGE), que são profissionais responsáveis por orientar os gestores escolares na coleta de dados, análise das variáveis que causam impacto nos resultados da escola, elaboração e acompanhamento do plano de ação. Os Agentes de Acompanhamento da Gestão Escolar são orientados por técnicos que formam o Comitê GIDE, que é o objeto de estudo da presente pesquisa. O Comitê GIDE monitora as ações dos AAGEs e a implantação do sistema nas unidades escolares. A presente pesquisa contemplou o estudo da rotina e dos principais desafios do Comitê GIDE, suas relações internas com as superintendências da Subsecretaria de Gestão de Ensino e suas relações com os Agentes de Acompanhamento da Gestão Escolar. Foram aplicados questionários aos superintendentes e aos AAGEs Representantes e, a partir dos resultados, foi proposto um Plano de Ação Educacional com o objetivo de sugerir ações para melhorar a rotina de trabalho dos técnicos do Comitê GIDE e aprimorar, de uma forma geral, os aspectos referentes às relações de trabalho com a Subsecretaria de Gestão de Ensino. / This research was developed under the Master's Graduate Professional Program in Management and Public Education Evaluation. In 2011, the Secretary of State of Rio de Janeiro Education adopted the Integrated Management School (GIDE) as management system, focusing on results. This work aimed to analyze the routine actions of GIDE Committee, responsible for monitoring the implementation of public policy of the state of Rio de Janeiro. To deploy the GIDE in schools, were selected from the School Management Monitoring Agents (AAGE), who are professionals responsible for guiding school managers in data collection, analysis of the variables that impact on school results, preparation and monitoring of the plan action. The School Management of the Monitoring Agents are guided by technicians who form the GIDE Committee, which is the object of study of this research. The GIDE Committee monitors the actions of Aages and deployment of GIDE at schools. This research included the study of the routine and the main challenges of GIDE Committee, its internal relationships with the superintendents of Education Management Secretariat and its relations with the School Management Monitoring Agents. Questionnaires were applied to superintendents and Aages representatives and from the results proposed an Educational Action Plan in order to suggest actions to improve the work routine of technicians GIDE Committee and improve, in general, the aspects concerning the working relationships with the Education Management Secretariat.
