    • Arbitration policies for on-demand user-level I/O forwarding on HPC platforms 

      Bez, Jean Luca; Miranda, Alberto; Nou Castell, Ramon; Zanon Boito, Francieli; Cortés, Toni; Navaux, Philippe O.A. (Institute of Electrical and Electronics Engineers (IEEE), 2021)
      Text en actes de congrés
      Accés obert
      I/O forwarding is a well-established and widely-adopted technique in HPC to reduce contention in the access to storage servers and transparently improve I/O performance. Rather than having applications directly accessing ...

    • ECHOFS: a scheduler-guided temporary filesystem to leverage node-local NVMS 

      Miranda, Alberto; Nou Castell, Ramon; Cortés, Toni (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Text en actes de congrés
      Accés obert
      The growth in data-intensive scientific applications poses strong demands on the HPC storage subsystem, as data needs to be copied from compute nodes to I/O nodes and vice versa for jobs to run. The emerging trend of adding ...

    • ETP4HPC’s SRA 5 strategic research agenda for High-Performance Computing in Europe 2022: European HPC research priorities 2023-2027 

      Carpenter, Paul Matthew; Casas, Marc; Unsal, Osman Sabri; Radojkovic, Petar; Martorell Bofill, Xavier; Miranda, Alberto; Guitart Fernández, Jordi; Corbalán González, Julita; Peña Monferrer, Antonio José; Bautista Gomez, Leonardo Arturo; Vázquez García, Miguel; Beltran Querol, Vicenç; Queralt Calafat, Anna; Nou Castell, Ramon; Borrell Pol, Ricard; Houzeaux, Guillaume; Serradell Maronda, Kim; Carrera Pérez, David; García Sáez, Artur; Puchol García, Carlos (2022-09)
      Report de recerca
      Accés obert
      This document feeds research and development priorities devel-oped by the European HPC ecosystem into EuroHPC’s Research and Innovation Advisory Group with an aim to define the HPC Technology research Work Programme and ...

    • GekkoFS: A temporary distributed file system for HPC applications 

      Vef, Marc-André; Moti, Nafiseh; Süb, Tim; Tocci, Tommaso; Nou Castell, Ramon; Miranda, Alberto; Cortés, Toni; Brinkmann, Andre (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Text en actes de congrés
      Accés obert
      We present GekkoFS, a temporary, highly-scalable burst buffer file system which has been specifically optimized for new access patterns of data-intensive High-Performance Computing (HPC) applications. The file system ...

    • HetFS: A heterogeneous file system for everyone 

      Koloventzos, Georgios; Nou Castell, Ramon; Miranda, Alberto; Cortés, Toni (Springer, 2017)
      Text en actes de congrés
      Accés obert
      Storage devices have been getting more and more diverse during the last decade. The advent of SSDs made it painfully clear that rotating devices, such as HDDs or magnetic tapes, were lacking in regards to response time. ...

    • Improving OpenStack Swift interaction with the I/O stack to enable software defined storage 

      Nou Castell, Ramon; Miranda, Alberto; Siquier, Marc; Cortés, Toni (Institute of Electrical and Electronics Engineers (IEEE), 2018)
      Text en actes de congrés
      Accés obert
      This paper analyses how OpenStack Swift, a distributed object storage service for a globally used middleware, interacts with the I/O subsystem through the Operating System. This interaction, which seems organised and clean ...

    • Performance impacts with reliable parallel file systems at exascale level 

      Nou Castell, Ramon; Miranda, Alberto; Cortés, Toni (Springer, 2015)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      The introduction of Exascale storage into production systems will lead to an increase on the number of storage servers needed by parallel file systems. In this scenario, parallel file system designers should move from the ...
