In order to achieve significant progress in computer science, new and powerful solutions in the field of information technology are required; some of the current processes would not be possible without access to powerful computing resources. This investigation focused on creating a system for harnessing these resources in a distributed environment called a grid. The grid is based on the sharing of distributed computing resources for multiple purposes in a computational process. Currently, researchers are required to understand some advanced concepts in order to incorporate all the advantages of grid architecture. The idea throughout this project was to create a portal oriented to researchers who wish to execute tasks using distributed resources, without their having to delve into the technical details of grid technologies. The first part of this article describes the basics for grid portals and the proposed model; the article subsequently emphasizes the components of the prototype including all relevant elements for modeling the portal, such as middleware, frameworks, web server, and portlets. Following is a brief description of the results achieved throughout the project, including the satisfactory performance of the portal, with the conclusion that the execution of tasks using distributed resources through the portal takes considerably less time than with other methods, in addition to being more user-friendly. Finally some significant recommendations for future work are identified.
