Designing parallel codes is hard. One of the most important roadblocks to parallel programming is the presence of data dependencies. These restrict parallelism and, in general, to work them around requires complex analysis ...
Los encargados de recursos Grid pueden autorizar el acceso a sus elementos de cómputo por medio de procedimientos bien establecidos para los clientes, regularmente a través del uso de credenciales criptográficas que en su ...
Matrix computations lie at the heart of most scientific computational tasks. The solution of linear systems of equations is a very frequent operation in many fields in science, engineering, surveying, physics and ...
Modern service-oriented applications demand the ability to adapt to changing conditions and unexpected situations while maintaining a required QoS. Existing self-adaptation approaches seem inadequate to address this challenge ...
Vehicular Ad-Hoc NETworks (VANETs) are an emerging technology which aims to improve road safety by preventing and reducing traffic accidents. While VANETs offer a great variety of promising applications, such as, safety-related ...
El creixement experimentat tant per la web com per Internet en els últims anys ha potenciat l'introducció de servidors d'aplicacions dins de la majoria d'entorns d'execució distribuits. El servidors d'aplicacions web porten ...
Diversos motius expliquen l'estancament en el que es troba el desenvolupament del processador tradicional dissenyat per maximitzar el rendiment d'un únic fil d'execució. Per una banda, técniques agressives com la supersegmentacó ...
La evolución de los procesadores siempre ha consistido en ir aumentando el rendimiento de estos, fijando como medida de este aumento de rendimiento la velocidad de proceso en la ejecución de las distintas aplicaciones. Sin ...
The evolution of network services is closely related to the network technology trend. Originally network nodes forwarded packets from a source to a destination in the network by executing lightweight packet processing, or ...
La utilización de aplicaciones de diferente naturaleza dentro de un mismo entorno, entorno heterogéneo, se está extendiendo gracias a la incorporación de técnicas de virtualización a los servidores. Compartir un servidor ...
High Performance Computing and Supercomputing is the high end area of the computing science that studies and develops the most powerful computers available. Current supercomputers are extremely complex so are the applications ...
Over the last decade, advances in technology together with the increasing use of the Internet for everyday tasks, are causing profound changes in end-users, as well as in businesses and technology providers. The widespread ...
Dos de las limitaciones de rendimiento más importantes en los procesadores de hoy en día provienen de las operaciones de memoria y de las dependencias de control. Para resolver estos problemas, las memorias cache y los ...
Complex hardware systems become more and more ubiquitous in mission critical applications such as military, satellite, and medical to name but a few. In such applications, reliability remains a primary concern because a ...
Technology improvements and power constrains have taken multicore architectures to dominate microprocessor designs over uniprocessors. At the same time, accelerator based architectures have shown that heterogeneous ...
This thesis takes a HW/SW collaborative approach to tackle the problem of computational inefficiency in a holistic manner. The hardware is redesigned by restraining the datapath to merely 16-bit datawidth (integer datapath ...
Esta tesis se enmarca en el ámbito de las técnicas de mejora de la eficiencia de ejecución (disminución del consumo y aumento de la velocidad) en el diseño de procesadores orientados a la ejecución de aplicaciones multimedia. ...
Power constraints led to the end of exponential growth in single–processor performance, which characterized the semiconductor industry for many years. Single–chip multiprocessors allowed the performance growth to continue ...
