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. ...
(English) In the last decade performance needs in Critical Real-Time Embedded Systems (CRTES) domains like automotive, avionics, railway or space have been steadily on the rise due to the unprecedented computational power ...
ISA extensions are a very powerful approach to implement new hardware techniques that require or benefit from compiler support: decisions made at compile time can be complemented at runtime, achieving a synergistic effect ...
Backbone networks are responsible for long-haul data transport serving many clients with a large volume of data. Since long-haul data transport service must rely on a robust high capacity network the current technology ...
The availability of the Information Technologies for everything, from everywhere, at all times is a growing requirement. We use information Technologies from common and social tasks to critical tasks like managing nuclear ...
Industry developing Critical Real-Time Embedded Systems (CRTES), such as Aerospace, Space, Automotive and Railways, faces relentless demands for increased guaranteed processor performance to support new advanced functionalities ...
The last decade has witnessed unprecedented changes in parallel and distributed infrastructures. Due to the diminished gains in processor performance from increasing clock frequency, manufacturers have moved from uniprocessor ...
This thesis contributes from the perspective of task-based programming models to the efforts of optimizing I/O intensive applications. Throughout this thesis, we propose programming model abstractions and mechanisms that ...
There is a clear trend nowadays to use heterogeneous high-performance computers, as they offer considerably greater computing power than homogeneous CPU systems. Extending traditional CPU systems with specialized units ...
For the last decade, mobile devices have grown in popularity and became the best-selling computing devices. Despite their high capabilities for user interactions and network connectivity, the computing power of mobile ...
Data Science workflows have become a must to progress in many scientific areas such as life, health, and earth sciences. In contrast to traditional HPC workflows, they are more heterogeneous; combining binary executions, ...
Transactional memory (TM) is a new optimistic synchronization technique which has the potential of making shared memory parallel programming easier compared to locks without giving up from the performance. This thesis ...
En esta tesis doctoral se presenta TAP (Trusted and Active Protocol PDU transfer), una arquitectura para redes de tecnología ATM, novedosa por sus características distribuida, activa y multiagente. El protocolo propuesto ...
