E-infrastructure shared between Europe and Latin America 13th EELA Tutorial, La Antigua, October 2007 FP62004Infrastructures6-SSA Introducción Que es Grid? –Grid puede ser comparado con una red eléctrica donde los usuarios pueden conectar cualquier dispositivo desde cualquier parte de ella sin necesidad de saber de donde proviene la energía. –Analógicamente, los usuarios de la GRID pueden conectar su computador a una red de recursos computacionales y acceder a la potencia de ellos sin necesidad de saber donde se encuentran estos recursos. –También se dice que es un cluster de clusters donde se agrupan recursos de computo separados geográficamente a través de una red de comunicación para tal fin. 3

E-infrastructure shared between Europe and Latin America 13th EELA Tutorial, La Antigua, October 2007 FP62004Infrastructures6-SSA Conceptos de GRID Recursos Computacionales –Equipos o computadores donde los usuarios puedan ejecutar jobs, aplicaciones, almacenar o recuperar datos sin importar el lugar geografico donde se encuentre dicho recurso. Job –Es una tarea computacional, (ejecutable o script) que los usuarios pueden ejecutar en el GRID con la finalidad de obtener un resultado final de regreso a un recurso al cual tenga acceso. Job Submission –Es el acto por el cual un usuario delega al GRID la responsabilidad de hallar el mejor recurso disponible en cualquier lugar del mundo y enviar el job para ser ejecutado en dicho recurso. 5
