Um portlet genérico para construção de portais web para grades computacionais utilizando o framework GridSphere

Abstract

Parallel and distributed processing is used nowadays as an efficient approach to problems that require high computing power. Computational grids stand out as an environment for such distributed execution. These platforms allow users that are geographically apart to use computer resources from other computers connected to the grid. However, using computational grids is not an easy task, because it requires the user to have some knowledge of distributed processing and operational systems, and also the use of advanced tools. Web portals that provide a friendly interface and a high level of advanced services to a grid can avoid this problem. Typically, a portal allows different authenticated users to configure experiments and to follow the execution of the application in the grid, using portlets specially designed for this purpose. The creation of portals and portlets is, however, a hard task, since it has to be repeated for every new application in a grid. In this context, this work proposes the development of generic portal able to generate portals to computional grids through the GridSphere framework. Through GridSphere it is possible to develop a Web interface that brings advantages in processes handling being executed in a grid, as well as in monitoring them. Besides this, through portlets technology, GridSphere allows users to configure the portal’s look and the tools they wish to access. This work intends to facilitate the creation of portals that allow the access and use of computional grids to be done in a simple and productive way.
