Virtualización de laboratorios

Para empezar, se ha hecho un análisis de las diferentes posibilidades que se podían implementar para poder conseguir el objetivo del trabajo. El resultado final debe ser, disponer de máquinas para que el sistema operativo fuese independiente del hardware que se tiene instalado en él . Para ello, se decide montar un sistema operativo de base en todos los equipos del laboratorio, que tenga las necesidades mínimas que se necesitan, las cuales son una interfaz gráfica y conexión de red. Hay que intentar reducir el consumo de recursos al máximo con este sistema operativo mínimo para que el rendimiento de las máquinas sea lo más fluido posible para los usuarios. El sistema elegido fue Linux con su distribución Ubuntu [ubu, http] con los módulos mínimos que permita funcionar el software necesario. Una vez se instala el sistema operativo anfitrión, se instala el escritorio Xfce [ubu2, http], que es el más ligero de Ubuntu, pero que proporciona buen rendimiento. Después, se procedió a instalar un software de virtualización en cada equipo. En este caso se decidió, por las buenas prestaciones que ofrecía, que fuera VirtualBox [vir2,http] de Oracle. Sobre éste software se crean tantas máquinas virtuales (con sistema operativo Windows) como asignaturas diferentes se cursan en el laboratorio donde se trabaje. Con esto, se consigue que al arrancar el programa los alumnos pudieran escoger qué máquina arrancar y lo que es más importante, se permite realizar cualquier cambio en el hardware (exceptuando el disco duro porque borraría todo lo que se tuviera guardado). Además de no tener que volver a reinstalar el sistema operativo nuevamente, se consigue la abstracción del software y hardware. También se decide que, para tener un respaldo de las máquinas virtuales que se tengan creadas en VirtualBox, se utiliza un servidor NAS. Uno de los motivos de utilizar dicho servidor fue por aprovechar una infraestructura ya creada. Un servidor NAS da la posibilidad de recuperar cualquier archivo (máquina virtual) cuando haga falta porque haya alguna máquina virtual corrupta en algún equipo, o en varios. Este tipo de servidor tiene la gran ventaja de ser multicast, es decir, permite solicitudes simultáneas. ABSTRACT For starters, there has been an analysis of the different possibilities that could be implemented to achieve the objective of the work. This objective was to have machines for the operating system to be independent of the hardware we have installed on it. Therefore, we decided to create an operating system based on all computers in the laboratory, taking the minimum needs we need. This is a graphical interface and network connection. We must try to reduce the consumption of resources to the maximum for the performance of the machines is as fluid as possible for users. The system was chosen with its Ubuntu Linux distribution with minimum modules that allow us to run software that is necessary for us. Once the base is installed, we install the Xfce desktop, which is the lightest of Ubuntu, but which provided good performance. Then we proceeded to install a virtualization software on each computer. In this case we decided, for good performance that gave us, it was Oracle VirtualBox. About this software create many virtual machines (Windows operating system) as different subjects are studied in the laboratory where we are. With that, we got it at program startup students could choose which machine start and what is more important, allowed us to make any changes to the hardware (except the hard drive because it would erase all we have). Besides not having to reinstall the operating system again, we get the software and hardware abstraction. We also decided that in order to have a backup of our virtual machines that we created in VirtualBox, we use a NAS server. One reason to use that server was to leverage their existing network infrastructure. A NAS server gives us the ability to retrieve any file (image) when we do need because there is some corrupt virtual machine in a team, or several. This is possible because this type of server allows multicast connection.

Introduction to Special issue on Reconfigurable computing and FPGAs

During the last three decades, FPGA technology has quickly evolved to become a major subject of research in computer and electrical engineering as it has been identified as a powerful alternative for creating highly efficient computing systems. FPGA devices offer substantial performance improvements when compared against traditional processing architectures via custom design and reconfiguration capabilities.
