Real-time high-performance computing for embedded control systems
(Universitat Politècnica de Catalunya, 2022-07-21)
Doctoral thesis
Open AccessThe real-time control systems industry is moving towards the consolidation of multiple computing systems into fewer and more powerful ones, aiming for a reduction in size, weight, and power. The increasing demand for higher ... -
Resilience for large ensemble computations
(Universitat Politècnica de Catalunya, 2022-07-01)
Doctoral thesis
Open AccessWith the increasing power of supercomputers, ever more detailed models of physical systems can be simulated, and ever larger problem sizes can be considered for any kind of numerical system. During the last twenty years ... -
Development of cognitive workload models to detect driving impairment
(Universitat Politècnica de Catalunya, 2021-09-20)
Doctoral thesis
Open AccessDriving a vehicle is a complex activity exposed to continuous changes such as speed limits and vehicular traffic. Drivers require a high degree of concentration when performing this activity, increasing the amount of mental ... -
Distributed collaborative knowledge management for optical network
(Universitat Politècnica de Catalunya, 2022-06-02)
Doctoral thesis
Open AccessNetwork automation has been long time envisioned. In fact, the Telecommunications Management Network (TMN), defined by the International Telecommunication Union (ITU), is a hierarchy of management layers (network element, ... -
Large scale geostatistics with locally varying anisotropy
(Universitat Politècnica de Catalunya, 2022-06-09)
Doctoral thesis
Open AccessClassical geostatistical methods are based on the hypothesis of stationarity, which allows to apply repetitive sampling in different locations of the spatial domain, in order to obtain enough information to infer cumulative ... -
Autonomous and reliable operation of multilayer optical networks

(Universitat Politècnica de Catalunya, 2022-05-23)
Doctoral thesis
Open AccessThe landscape of High Performance Computing (HPC) system architectures keeps expanding with new technologies and increased complexity. To improve the efficiency of next-generation compute devices, architects are looking ... -
Exploiting data locality in cache-coherent NUMA systems
(Universitat Politècnica de Catalunya, 2022-04-06)
Doctoral thesis
Open AccessThe end of Dennard scaling has caused a stagnation of the clock frequency in computers.To overcome this issue, in the last two decades vendors have been integrating larger numbers of processing elements in the systems, ... -
Adaptable register file organization for vector processors
(Universitat Politècnica de Catalunya, 2022-04-04)
Doctoral thesis
Open AccessToday there are two main vector processors design trends. On the one hand, we have vector processors designed for long vectors lengths such as the SX-Aurora TSUBASA which implements vector lengths of 256 elements (16384-bits). ... -
