Since the invention of the transistor, clock frequency increase was the primary method of improving computing performance. As the reach of Moore's law came to an end, however, technology driven performance gains became ...
SIMD accelerators are ubiquitous in microprocessors from different computing domains. Their high compute power and hardware simplicity improve overall performance in an energy efficient manner. Moreover, their replicated ...
The growing interest that multimedia processing has experimented during the last decade is motivating processor designers to reconsider which execution paradigms are the most appropriate for general-purpose processors. On ...
In the Internet of services, information technology (IT) infrastructure providers play a critical role in making the services accessible to end-users. IT infrastructure providers host platforms and services in their ...
In recent years there has been an extraordinary growth of the Internet of Things (IoT) and its protocols. The increasing diffusion of electronic devices with identification, computing and communication capabilities is ...
La programació d'aplicacions en màquines paral·leles és un tema d'interès quant a que cada vegada són més les màquines d'aquest tipus disponibles comercialment.<br><br/>Per a això l'usuari disposa de dues opcions: (a) ...
This thesis is based on the implementation of a computational system to numerically simulate the interaction between a fluid and an arbitrary number of rigid bodies. This implementation was performed in a distributed ...
The increasing parallelism levels in modern computing systems has extolled the need for a holistic vision when designing multiprocessor architectures taking in account the needs of the programming models and applications. ...
Digital video is a popular technology used in many different applications. The quality of video, expressed in the spatial and temporal resolution, has been increasing continuously in the last years. In order to reduce the ...
During the last two decades, High-Performance Computing (HPC) has grown rapidly in performance by improving single-core processors at the cost of a similar growth in power consumption. The single-core processor improvement ...
Chip multi-core processors (CMPs) are the preferred processing platform across different domains such as data centers, real-time systems and mobile devices. In all those domains, energy is arguably the most expensive ...
The so-called "power (or power density) wall" has caused core frequency (and single-thread performance) to slow down, giving rise to the era of multi-core/multi-thread processors. For example, the IBM POWER4 processor, ...
The sheer increase in volume of data over the last decade has triggered research in cluster computing frameworks that enable web enterprises to extract big insights from big data. While Apache Spark defines the state of ...
El disseny del llenguatge Java, que inclou aspectes importants com són la seva portabilitat i neutralitat envers l'arquitectura, les seves capacitats multithreading, la seva familiaritat (degut a la seva semblança amb ...
La predicció és un concepte de recerca molt interessant. No es només predir el resultat futur, sinó que també cal predir el resultat conegut, a vegades anomenat validació. <br/><br/>L'aplicació de tècniques de predicció ...
Recently the community started looking into Hardware/Software (HW/SW) co-designed processors as potential solutions to move towards the less power consuming and the less complex designs. Unlike other solutions, they reduce ...
Energy efficiency is an important challenge in the field of High Performance Computing (HPC). High energy requirements not only limit the potential to realize next-generation machines but are also an increasing part of the ...
Esta tesis afronta el problema de la planificación de sistemas de tiempo real utilizando sistemas multiprocesador con memoria compartida. Según laliteratura este problema es NP-Hard. En las aplicaciones de sistemas de ...
The scaling of silicon technology has been ongoing for over forty years. We are on the way to commercializing devices having a minimum feature size of one-tenth of a micron. The push for miniaturization comes from the ...
As the transistor budgets outpace the power envelope (the power-wall issue), new architectural and microarchitectural techniques are needed to improve, or at least maintain, the power efficiency of next-generation processors. ...
