  • Aggressive undervolting of FPGAs : power & reliability trade-offs 

    Salami, Behzad (Universitat Politècnica de Catalunya, 2018-11-19)
    Doctoral thesis
    Open Access
    In this work, we evaluate aggressive undervolting, i.e., voltage underscaling below the nominal level to reduce the energy consumption of Field Programmable Gate Arrays (FPGAs). Usually, voltage guardbands are added by ...
  • Improving the performance and energy-efficiency of virtual memory 

    Karakostas, Vasileios (Universitat Politècnica de Catalunya, 2016-04-18)
    Doctoral thesis
    Open Access
    Virtual memory improves programmer productivity, enhances process security, and increases memory utilization. However, virtual memory requires an address translation from the virtual to the physical address space on every ...
  • Multicore architecture prototyping on reconfigurable devices 

    Arcas Abella, Oriol (Universitat Politècnica de Catalunya, 2016-04-15)
    Doctoral thesis
    Open Access
    In the the last decades several performance walls were hit. The memory wall and the power wall are limiting the performance scaling of digital microprocessors. Homogeneous multicores rely on thread-level parallelism, which ...
  • A multicore emulator with a profiling infrastructure for transactional memory on FPGA 

    Sönmez, Nehir (Universitat Politècnica de Catalunya, 2012-09-19)
    Doctoral thesis
    Open Access
    This thesis attempts to bring together two recent topics by presenting a flexible Transactional Memory environment on a multicore prototype that is realized on FPGA fabric. For this, we devise a MIPS-compatible shared-memory ...
  • Reliability for exascale computing : system modelling and error mitigation for task-parallel HPC applications 

    Subasi, Omer (Universitat Politècnica de Catalunya, 2016-10-27)
    Doctoral thesis
    Open Access
    As high performance computing (HPC) systems continue to grow, their fault rate increases. Applications running on these systems have to deal with rates on the order of hours or days. Furthermore, some studies for future ...
