    Chasapis, Dimitrios (Date of defense: 2019-04-24)

    Current large scale systems show increasing power demands, to the point that it has become a huge strain on facilities and budgets. The increasing restrictions in terms of power consumption of High Performance Computing ...

    Trade-off among timeliness, messages and accuracy for large-Ssale information management 

    Brunner, René (Date of defense: 2011-11-18)

    The increasing amount of data and the number of nodes in large-scale environments require new techniques for information management. Examples of such environments are the decentralized infrastructures of Computational ...

    Traffic Management of the ABR. Service Category in ATM Networks 

    Cerdà Alabern, Llorenç (Date of defense: 2000-01-13)

    Data traffic has emerged as a big challenge for the standardization of traffic management mechanisms in ATM networks. In April 1996 the ATM Forum published the first version of the Available Bit Rate Service Category (ABR) ...

    Transparent management of scratchpad memories in shared memory programming models 

    Álvarez Martí, Lluc (Date of defense: 2015-12-16)

    Cache-coherent shared memory has traditionally been the favorite memory organization for chip multiprocessors thanks to its high programmability. In this organization the cache hierarchy is in charge of moving the data and ...
