An ontology-based approach toward the configuration of heterogeneous network devices
Despite the numerous efforts of standardization, semantic issues remain in effect in many subfields of networking. The inability to exchange data unambiguously between information systems and human resources is an issue ...
Energy-efficient mobile GPU systems
The design of mobile GPUs is all about saving energy. Smartphones and tablets are battery-operated and thus any type of rendering needs to use as little energy as possible. Furthermore, smartphones do not include sophisticated ...
Performance simulation methodologies for hardware/software co-designed processors
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 ...
A dependency-aware parallel programming model
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 ...
The use of computational intelligence for security in named data networking
Information-Centric Networking (ICN) has recently been considered as a promising paradigm for the next-generation Internet, shifting from the sender-driven end-to-end communication paradigma to a receiver-driven content ...
Designs for increasing reliability while reducing energy and increasing lifetime
In the last decades, the computing technology experienced tremendous developments. For instance, transistors' feature size shrank to half at every two years as consistently from the first time Moore stated his law. ...
A pragmatic approach toward securing inter-domain routing
Internet security poses complex challenges at different levels, where even the basic requirement of availability of Internet connectivity becomes a conundrum sometimes. Recent Internet service disruption events have made ...
Resource management techniques aware of interference among high-performance computing applications
Network interference of nearby jobs has been recently identified as the dominant reason for the high performance variability of parallel applications running on High Performance Computing (HPC) systems. Typically, HPC ...
A novel access pattern-based multi-core memory architecture
Increasingly High-Performance Computing (HPC) applications run on heterogeneous multi-core platforms. The basic reason of the growing popularity of these architectures is their low power consumption, and high throughput ...
Resilience mechanisms for carrier-grade networks
In recent years, the advent of new Future Internet (FI) applications is creating ever-demanding requirements. These requirements are pushing network carriers for high transport capacity, energy efficiency, as well as ...
Atomic dataflow model
With the recent switch in the design of general purpose processors from frequency scaling of a single processor core towards increasing the number of processor cores, parallel programming became important not only for ...
Electromechanical large scale computational models of the ventricular myocardium
Els models computacionals del cor són una eina important que pot donar als investigadors biomèdics una font addicional d’informació per entendre el funcionament del miocardi. Els models numèrics poden ajudar a interpretar ...
Off-line and in-operation optical core networks planning
The ever increasing IP traffic volume has finally brought to light the high inefficiency of current wavelength-routed over rigid-grid optical networks in matching the client layer requirements. Such an issue results in the ...
Network traffic classification : from theory to practice
Since its inception until today, the Internet has been in constant transformation. The analysis and monitoring of data networks try to shed some light on this huge black box of interconnected computers. In particular, the ...
Scalability in extensible and heterogeneous storage systems
The evolution of computer systems has brought an exponential growth in data volumes, which pushes the capabilities of current storage architectures to organize and access this information effectively: as the unending ...
Hardware design of task superscalar architecture
Exploiting concurrency to achieve greater performance is a difficult and important challenge for current high performance systems. Although the theory is plain, the complexity of traditional parallel programming models in ...
Optimizing SIMD execution in HW/SW co-designed processors
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 ...
Self-organized backpressure routing for the wireless mesh backhaul of small cells
The ever increasing demand for wireless data services has given a starring role to dense small cell (SC) deployments for mobile networks, as increasing frequency re-use by reducing cell size has historically been the most ...
HERMESH : a geometrical domain composition method in computational mechanics
With this thesis we present the HERMESH method which has been classified by us as a a composition domain method. This term comes from the idea that HERMESH obtains a global solution of the problem from two independent ...
Information dissemination in mobile networks
This thesis proposes some solutions to relieve, using Wi-Fi wireless networks, the data consumption of cellular networks using cooperation between nodes, studies how to make a good deployment of access points to optimize ...
