Resumen
El incremento en las necesidades de cómputo requeridos por los proyectos científicos presenta
un reto para la comunidad de investigadores, lo cual, exige explorar nuevas tecnologías de
computación distribuidas para buscar soluciones a sus demandas. La computación Grid
propone una solución fiable y eficiente para conectar recursos heterogéneos y distribuidos
entre diferentes organizaciones virtuales utilizando algún tipo de redes de comunicación.
Actualmente, existen diversas herramientas que proveen una plataforma para desarrollar
sistemas Grid, de ellas, se destaca Globus Toolkit, por su gran aceptación a nivel mundial.
La Universidad Central “Marta Abreu” de Las Villas, carece de un sistema capaz de agrupar
todas las potencias de cómputos existentes, por lo cual, este trabajo propone explorar la
tecnología Grid y como extenderla en la UCLV, mediante el diseño e implementación de una
infraestructura Grid, simulada virtualmente, para el Centro de Estudios de Informática (CEI).
Para la conformación del mini-grid virtual, resultó preciso la instalación y configuración de la
herramienta Globus Toolkit 5.2.2, además, un conjunto de software necesario para el
funcionamiento del Grid. La integración entre administradores de recursos locales y el
componente GRAM, que ofrece Globus, es sumamente necesaria, ya que este último no tiene
la capacidad de ejecutar trabajos en paralelo por sí mismo, sino que lo hace a través del
administrador de recursos locales.
Las pruebas de funcionamiento llevadas a cabo en el mini-grid mostraron: el correcto
funcionamiento del sistema y proporcionaron resultados similares a los obtenidos mediante la
ejecución de las mismas tareas empleando comandos PBS o de la biblioteca MPI.
The increased computing needs required by scientific projects presents a challenge for the research community, which requires exploring new distributed computing technologies to find solutions to their demands. Grid computing offers a reliable and efficient solution for connecting heterogeneous and distributed resources between different virtual organizations using any type of communication networks. Currently, there are various tools that provide a platform for developing Grid systems, including Globus Toolkit stands out for its wide acceptance worldwide. The Central University "Marta Abreu" of Las Villas, lacks a system to group all installed power computations, therefore, this paper will explore the Grid technology and how to extent it to the UCLV through the design and implementation of a Grid infrastructure, virtually simulated, for the Centre on Informatics Studies (CEI). For the implementation of the virtual mini-grid, was necessary the installation and configuration of the tool Globus Toolkit 5.2.2 also a set of software needed to operate the Grid. The integration between local resource managers and the GRAM component that offers Globus, it is extremely necessary since the latter does not have the ability to run parallel jobs by itself, but does so through the local resource manager. Performance tests carried out on the mini-grid showed: the proper functioning of the system, obtained results similar to those obtained by performing the same tasks, using PBS or MPI library commands.
