    • Ad hoc file systems for high-performance computing 

      Brinkmann, Andre; Mohror, Kathryn; Yu, Weikuan; Carns, Philip; Cortés, Toni; Klasky, Scott A.; Miranda Bueno, Alberto; Pfreundt, Franz-Josef; Ross, Robert B.; Vef, Marc-André (2020-01-17)
      Open Access
      Storage backends of parallel compute clusters are still based mostly on magnetic disks, while newer and faster storage technologies such as flash-based SSDs or non-volatile random access memory (NVRAM) are deployed within ...
    • Compressió de memòria per a la millora de l'eficiència energètica 

      Zhu Wang, Liang Xiao (Universitat Politècnica de Catalunya, 2008-07-04)
      Master thesis (pre-Bologna period)
      Open Access
    • Continuous-action reinforcement learning for memory allocation in virtualized servers 

      Garrido Platero, Luis Ángel; Nishtala, Rajiv; Carpenter, Paul Matthew (Springer, 2019)
      Conference report
      Open Access
      In a virtualized computing server (node) with multiple Virtual Machines (VMs), it is necessary to dynamically allocate memory among the VMs. In many cases, this is done only considering the memory demand of each VM without ...
    • Efficient exception handling support for GPUs 

      Tanasic, Ivan; Gelado Fernandez, Isaac; Jorda, Marc; Ayguadé Parra, Eduard; Navarro, Nacho (Association for Computing Machinery (ACM), 2017)
      Conference report
      Restricted access - publisher's policy
      Operating systems have long relied on the exception handling mechanism to implement numerous virtual memory features and optimizations. However, today's GPUs have a limited support for exceptions, which prevents implementation ...
    • 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 ...
    • Microarchitectural support for speculative register renaming 

      Alastruey, Jesús; Monreal Arnal, Teresa; Viñals Yufera, Víctor; Valero Cortés, Mateo (Institute of Electrical and Electronics Engineers (IEEE), 2007)
      Conference report
      Open Access
      This paper proposes and evaluates a new microarchitecture for out-of-order processors that supports speculative renaming. We call speculative renaming to the speculative omission of physical register allocation along with ...
