      Hayes, Timothy (Universitat Politècnica de Catalunya, 2011-09-20)
      Master thesis
      Open Access
      English: This work takes a top-down approach to accelerating decision support systems (DSS) on x86-64 microprocessors using true vector ISA extensions. First, a state of art DSS database management system (DBMS) is pro ...
    • Future vector microprocessor extensions for data aggregations 

      Hayes, Timothy; Palomar, Oscar; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2016)
      Conference lecture
      Open Access
      As the rate of annual data generation grows exponentially, there is a demand to aggregate and summarise vast amounts of information quickly. In the past, frequency scaling was relied upon to push application throughput. ...

    • Runtime-aware architectures 

      Casas Guix, Marc; Moreto Planas, Miquel; Álvarez Martí, Lluc; Castillo Villar, Emilio; Chasapis, Dimitrios; Hayes, Timothy; Jaulmes, Luc; Palomar Pérez, Óscar; Unsal, Osman Sabri; Cristal Kestelman, Adrián; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Valero Cortés, Mateo (Springer, 2015)
      Conference report
      Open Access
      In the last few years, the traditional ways to keep the increase of hardware performance to the rate predicted by the Moore’s Law have vanished. When uni-cores were the norm, hardware design was decoupled from the software ...
