AutoMan: gerência automática de grades computacionais entre-pares.

Abstract

Grid computing has been more and more adopted in eScience and in companies. One important challenge in grid systems is the ability for automatic management, improving grid availability and simplifying administrators work. In this work we present AutoMan, a system whose main objective is to provide some degree of automatic management to a free-to-join peer-to-peer grid system, optimizing the utilization of perishable resources in the grid and simplifying the management of the system. The main contributions of this work are: a) the architecture and implementation proposed for AutoMan; and b) a discussion on the lessons learned from applying automatic management to a OurGrid grid system. We show through an evaluation that, when compared to a manual management approach, AutoMan substantially improves the grid availability.
