    • 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)
      Article
      Accés obert
      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 ...

    • Adaptive request scheduling for the I/O forwarding layer using reinforcement learning 

      Bez, Jean Luca; Zanon Boito, Francieli; Nou Castell, Ramon; Miranda Bueno, Alberto; Cortés, Toni; Navaux, Philippe O.A. (Elsevier, 2020-11)
      Article
      Accés obert
      In this paper, we propose an approach to adapt the I/O forwarding layer of HPC systems to applications’ access patterns. I/O optimization techniques can improve performance for the access patterns they were designed to ...

    • Analyzing long-term access locality to find ways to improve distributed storage systems 

      Miranda Bueno, Alberto; Cortés, Toni (2012)
      Text en actes de congrés
      Accés obert
      An efficient design for a distributed filesystem originates from a deep understanding of common access patterns and user behavior which is obtained through a deep analysis of traces and snapshots. In this paper we analyze ...

    • CRAID: Online RAID upgrades using dynamic hot data reorganization 

      Miranda Bueno, Alberto; Cortés, Toni (USENIX Association, 2014)
      Text en actes de congrés
      Accés obert
      Current algorithms used to upgrade RAID arrays typically require large amounts of data to be migrated, even those that move only the minimum amount of data required to keep a balanced data load. This paper presents CRAID, ...

    • GekkoFS: A temporary burst buffer file system for HPC applications 

      Vef, Marc-André; Moti, Nafiseh; Süb, Tim; Tacke, Markus; Tocci, Tommaso; Nou, Ramon; Miranda Bueno, Alberto; Cortés, Toni; Brinkmann, Andre (2020-01-17)
      Article
      Accés obert
      Many scientific fields increasingly use high-performance computing (HPC) to process and analyze massive amounts of experimental data while storage systems in today’s HPC environments have to cope with new access patterns. ...

    • Reliable and randomized data distribution strategies for large scale storage systems 

      Miranda Bueno, Alberto; Effert, S.; Kang, Y.; Miller, E.L.; Brinkmann, A.; Cortés, Toni (2011)
      Text en actes de congrés
      Accés obert
      The ever-growing amount of data requires highly scalable storage solutions. The most flexible approach is to use storage pools that can be expanded and scaled down by adding or removing storage devices. To make this approach ...

    • Scalability in extensible and heterogeneous storage systems 

      Miranda Bueno, Alberto (Universitat Politècnica de Catalunya, 2014-09-26)
      Tesi
      Accés obert
      The evolution of computer systems has brought an exponential growth in data volumes, which pushes the capabilities of current storage architectures to organize and access this information effectively: as the unending ...

    • Towards on-demand I/O forwarding in HPC platforms 

      Bez, Jean Luca; Zanon Boito, Francieli; Miranda Bueno, Alberto; Nou Castell, Ramon; Cortés, Toni; Navaux, Philippe O.A. (Institute of Electrical and Electronics Engineers (IEEE), 2020)
      Text en actes de congrés
      Accés obert
      I/O forwarding is an established and widely-adopted technique in HPC to reduce contention and improve I/O performance in the access to shared storage infrastructure. On such machines, this layer is often physically deployed ...
