    Gómez Crespo, Constantino (Universitat Politècnica de Catalunya, 2022-05-23)
    Doctoral thesis
    Open Access
    The 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 

    Sánchez Barrera, Isaac (Universitat Politècnica de Catalunya, 2022-04-06)
    Doctoral thesis
    Open Access
    The 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 

    Ramírez Lazo, Cristóbal (Universitat Politècnica de Catalunya, 2022-04-04)
    Doctoral thesis
    Open Access
    Today 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). ...
  • Smart hardware designs for probabilistically-analyzable processor architectures 

    Benedicte Illescas, Pedro (Universitat Politècnica de Catalunya, 2022-04-07)
