Abstract
Debido a la aparición de problemas cada vez más complejos y pesados computacionalmente hablando, resulta casi indispensable recurrir al uso de clusters de altas prestaciones, o HPCC, para reducir sensiblemente el tiempo de ejecución o ser capaces de abordar el inmenso tamaño de estos. Sin embargo, para la mayoría de usuarios el acceso a estos HPCC es tedioso e, incluso, complicado. Para superar esta barrera de entrada, en este Proyecto Fin de Carrera se describe una herramienta segura, sencilla y fácil de usar para proporcionar el acceso a los servicios de uno de estos clusters. De esta forma, se implementa un protocolo específico de comunicaciones con el cual se ofrecen funcionalidades como la ejecución remota de problemas en un HPCC o la transferencia automática de los ficheros de entrada y salida del trabajo ejecutado. Asimismo, se ha desarrollado una interfaz gráfica basada en Java para facilitar el control de estas funcionalidades por el usuario desde un equipo de sobremesa y, además, se ha implementado una aplicación en Android que mantiene los mismos servicios que la interfaz de sobremesa en un dispositivo móvil, dotando así de movilidad a la aplicación desarrollada. _________________________________________________________________________________________________________________________
As a result of the existence of problems more and more complex and computationally expensive, it is a must to use of high performance computational clusters, or HPCC, in order so as to appreciably reduce the time of execution and be capable of solve such problems. However, for a novice user the access to one of this resources can be di fficult and even unpleasant. This Final Project is developed to solve this barrier to entry. A simple, secure and user-friendly tool to provide the access to the services of one of these clusters is described. Thus, a speci c communication protocol is implemented, which provides features as the remote execution of problems in a HPCC or the automatic file transfer of the input and output les of the executed job. Likewise, a GUI (Graphical User Interface) based on Java has been developed to simplify these features in a desktop computer or laptop. And also, an Android application has been implemented in order to increase the mobility keeping all features from the original GUI.
