    • 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)
      Conference report
      Open Access
      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 ...
    • 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)
      Conference report
      Open Access
      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)
      Conference report
      Open Access
      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)
      Conference report
      Open Access
      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)
      Conference report
      Restricted access - publisher's policy
      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 ...
