      Doctoral thesis
      Open Access
      Asymmetric multi-cores (AMCs) are a successful architectural solution for both mobile devices and supercomputers. These architectures combine different types of processing cores designed at different performance and power ...
    • Exploiting task-based programming models for resilience 

      Jaulmes, Luc Etienne (Universitat Politècnica de Catalunya, 2019-06-21)
      Doctoral thesis
      Open Access
      Hardware errors become more common as silicon technologies shrink and become more vulnerable, especially in memory cells, which are the most exposed to errors. Permanent and intermittent faults are caused by manufacturing ...

    • Runtime-assisted optimizations in the on-chip memory hierarchy 

      Dimić, Vladimir (Universitat Politècnica de Catalunya, 2020-11-27)
      Doctoral thesis
      Open Access
      Following Moore's Law, the number of transistors on chip has been increasing exponentially, which has led to the increasing complexity of modern processors. As a result, the efficient programming of such systems has become ...
    • Simulation methodologies for future large-scale parallel systems 

      Grass, Thomas (Universitat Politècnica de Catalunya, 2017-10-09)
      Doctoral thesis
      Open Access
      Since the early 2000s, computer systems have seen a transition from single-core to multi-core systems. While single-core systems included only one processor core on a chip, current multi-core processors include up to tens ...
