The recent development of delay-sensitive applications has led to the emergence of the fog computing paradigm. Within this paradigm, computation nodes present at the edge of the network can act as fog nodes (FNs) capable ...
Over last years the number of Big Data, supercomputing, Internet of Things (IoT) or edge systems has snowballed. The core part of many areas and services in academia and business, are large, distributed, and complex IT ...
Existen numerosos trabajos que estudian o tratan la realización software de los protocolos de comunicaciones para el acceso a la Internet-TCP/IP. Sin embargo, no conocemos ninguno que modele de forma general y precisa la ...
(English) Critical Real-Time Embedded Systems (CRTES) are used in domains like transportation (e.g. avionics, automotive, space, and railway), healthcare, and industrial machinery. This subset of embedded systems requires ...
Se presentan una serie de modelos analíticos que son de utilidad para la evaluación de mecanismos de control de tráfico en redes digitales de servicios integrados de alta velocidad que usan conmutación de paquetes. En ...
La Tesis Doctoral "Modelos de seguridad para móviles" tiene como principal objetivo la definición de una arquitectura de seguridad para los sistemas de telefonía móvil de segunda generación, que permita soslayar los problemas ...
El objetivo de la tesis "Modelos para Comercio Electrónico basados en Sistemas Intermediarios" es el estudio, desarrollo y aplicación de una serie de modelos para sistemas de comercio electrónico abiertos que utilicen un ...
Interconnection networks represent the backbone of large-scale parallel systems. In order to build ultra-scale supercomputers larger interconnection networks are being designed and deployed. As compute nodes become more ...
Even today supercomputing systems have already reached millions of cores for a single machine, which are connected by using a complex network interconnection. Reducing communication time across processes becomes the most ...
Les xarxes mòbils ad-hoc, també conegues com a MANETs, han estat des de fa ja molt temps objectiu d'estudi per part de la comunitat científica. No obstant això, la seva importància dins el món de la indústria és encara ...
(English) In the wake of a digital revolution, contemporary society finds itself entrenched in an era where network applications' demands surpass the capabilities of conventional network management solutions. This dissertation ...
In recent years there has been an extraordinary growth of large-scale data processing and related technologies in both, industry and academic communities. This trend is mostly driven by the need to explore the increasingly ...
From single-core CPUs to detachable compute accelerators, supercomputers made a tremendous progress by using available transistors on chip and specializing hardware for a given type of computation. Today, compute nodes ...
In the the last decades several performance walls were hit. The memory wall and the power wall are limiting the performance scaling of digital microprocessors. Homogeneous multicores rely on thread-level parallelism, which ...
This thesis attempts to bring together two recent topics by presenting a flexible Transactional Memory environment on a multicore prototype that is realized on FPGA fabric. For this, we devise a MIPS-compatible shared-memory ...
Last decade, providers started using Virtual Machines (VMs) in their datacenters to pack users and their applications. This was a good way to consolidate multiple users in fewer physical nodes while isolating them from ...
La motivación principal de esta tesis es el desarrollo de nuevas técnicas de compilación dirigidas a conseguir mayor rendimiento encódigos numéricos complejos que definen es pacios de iteraciones no rectangulares. En ...
With the proliferation of smart devices that require Internet connectivity anytime, anywhere, and the recent technological advances that make it possible, current networked systems will have to provide a various range of ...
Since its inception until today, the Internet has been in constant transformation. The analysis and monitoring of data networks try to shed some light on this huge black box of interconnected computers. In particular, the ...
