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 ...
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 ...
