    Distributed Real-Time Media Processing refers to classes of highly distributed, delay no-tolerant applications that account for the majority of the data traffic generated in the world today. Real-Time audio/video conferencing ...
  • On the service placement in community network micro-clouds 

    Selimi, Mennan (Universitat Politècnica de Catalunya, 2017-05-22)
    Tesi
    Accés obert
    Community networks (CNs) have gained momentum in the last few years in response to the growing demand for network connectivity in rural and urban areas. These networks, owned and managed by volunteers, offer various services ...
  • Internet sharing in community networks 

    Dimogerontakis, Emmanouil (Universitat Politècnica de Catalunya, 2017-05-26)
    Tesi
    Accés obert
    The majority of the world's population does not have any or adequate Internet access. This implies that the Internet cannot provide universal service, reaching everyone without discrimination. Global access to the Internet ...
  • Dynamic load balancing for hybrid applications 

    Garcia Gasulla, Marta (Universitat Politècnica de Catalunya, 2017-04-18)
    Tesi
    Accés obert
    It is well known that load imbalance is a major source of efficiency loss in HPC (High Performance Computing) environments. The load imbalance problem has very different sources, from static ones related to the data ...
  • Towards multiprogrammed GPUs 

    Tanasić, Ivan (Universitat Politècnica de Catalunya, 2017-02-17)
    Tesi
    Accés obert
    Programmable Graphics Processing Units (GPUs) have recently become the most pervasitheve massively parallel processors. They have come a long way, from fixed function ASICs designed to accelerate graphics tasks to a ...
  • dataClay : next generation object storage 

    Martí Fraiz, Jonathan (Universitat Politècnica de Catalunya, 2017-03-31)
    Tesi
    Accés obert
    Existing solutions for data sharing are not fully compatible with multi-provider contexts. Traditionally, providers offer their datasets through hermetic Data Services with restricted APIs. Therefore, consumers are compelled ...
  • Design of energy-efficient vector units for in-order cores 

    Stanić, Milan (Universitat Politècnica de Catalunya, 2017-01-31)
    Tesi
    Accés obert
    In the last 15 years, power dissipation and energy consumption have become crucial design concerns for almost all computer systems. Technology feature size scaling leads to higher power density and therefore to complex and ...
  • On the design of power- and energy-efficient functional units for vector processors 

    Ratković, Ivan (Universitat Politècnica de Catalunya, 2016-12-14)
    Tesi
    Accés obert
    Vector processors are a very promising solution for mobile devices and servers due to their inherently energy-efficient way of exploiting datalevel parallelism. While vector processors succeeded in the high performance ...
  • Improving prefetching mechanisms for tiled CMP platforms 

    Torrents Lapuerta, Martí (Universitat Politècnica de Catalunya, 2016-11-28)
    Tesi
    Accés obert
    Recently, high performance processor designs have evolved toward Chip-Multiprocessor (CMP) architectures to deal with instruction level parallelism limitations and, more important, to manage the power consumption that is ...
  • Performance-aware energy optimizations in networks for HPC 

    Saravanan, Karthikeyan P. (Universitat Politècnica de Catalunya, 2016-11-02)
    Tesi
    Accés obert
    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 ...
