The growth of the Internet impacts multiple areas of the world economy, and it has become a permanent part of the economic landscape both at the macro- and at microeconomic level. On-line traffic and information are currently ...
Researchers from both academia and industry agree that future CMPs will accommodate large shared on-chip last-level caches. However, the exponential increase in multicore processor cache sizes accompanied by growing on-chip ...
Internet and communication technologies have lowered the costs for communities to collaborate, leading to new services like user-generated content and social computing, and through collaboration, collectively built ...
Albeit several IoT applications have been recently deployed in several fields, including environment and industry monitoring, Smart Home, Smart Hospital and Smart Agriculture, current deployments are mostly host-oriented, ...
Les xarxes IP tradicionals utilitzen el model de transmissió "best-effort" per transportar tràfic entre clients de la xarxa. Aquest model de transmissió de tràfic no és el més adequat per les aplicacions en temps real com ...
El uso de los entornos virtualizados de ejecución se ha extendido a todos los ámbitos y, en particular, se está utilizando para el desarrollo y la ejecución de aplicaciones con un alto consumo de recursos. Por lo tanto, ...
Most computing systems are heavily dependent on their main memories, as their primary storage, or as an intermediate cache for slower storage systems (HDDs). The capacity of memory systems, as well as their performance, ...
A major contributor to the deployment and operational costs of a large-scale high-performance computing (HPC) clusters is the memory system. In terms of system performance it is one of the most critical aspects of the ...
Efficiently managing the memory subsystem of modern multi/manycore architectures is increasingly becoming a challenge as systems grow in complexity and heterogeneity. In the field of high performance computing (HPC) in ...
Memory systems are signicant contributors to the overall power requirements, energy consumption, and the operational cost of large high-performance computing systems (HPC). Limitations of main memory systems in terms of ...
(English) The dominant programming approach for scientific and industrial computing on clusters is MPI+X. While there are a variety of approaches within the node, denoted by the ``X'', Message Passing interface (MPI) is ...
La dependencia de datos es una de las principales razones que limitan el rendimiento de los procesadores actuales. Algunos estudios han demostrado, que las aplicaciones no pueden alcanzar más de una decena de instrucciones ...
In the last decade, industry made a right-hand turn and shifted towards multi-core processor designs, also known as Chip-Multi-Processors (CMPs), in order to provide further performance improvements under a reasonable power ...
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 ...
