    • A model of checkpoint behavior for applications that have I/O 

      León, Betzabeth; Méndez, Sandra; Franco, Daniel; Rexachs, Dolores; Luque, Emilio (Springer, 2022-04)
      Article
      Open Access
      Due to the increase and complexity of computer systems, reducing the overhead of fault tolerance techniques has become important in recent years. One technique in fault tolerance is checkpointing, which saves a snapshot ...

    • An approach for an efficient execution of SPMD applications on Multi-core environments 

      Muresano, Ronal; Meyer, Hugo; Rexachs, Dolores; Luque, Emilio (Elsevier, 2017-01)
      Article
      Open Access
      Executing traditional Message Passing Interface (MPI) applications on multi-core cluster balancing speed and computational efficiency is a difficult task that parallel programmers have to deal with. For this reason, ...

      Conference report
      Restricted access - publisher's policy
      Nowadays, Deep Learning (DL) applications have become a necessary solution for analyzing and making predictions with big data in several areas. However, DL applications introduce heavy input/output (I/O) loads on computer ...

    • Hybrid Message Pessimistic Logging. Improving current pessimistic message logging protocols 

      Meyer, Hugo; Muresano, Ronal; Castro-León, Marcela; Rexachs, Dolores; Luque, Emilio (Elsevier, 2017-06-01)
      Article
      Open Access
      With the growing scale of HPC applications, there has been an increase in the number of interruptions as a consequence of hardware failures. The remarkable decrease of Mean Time Between Failures (MTBF) in current systems ...

    • Methodology to select a I/O configuration (hardware resources and stack software) in cloud platform 

      Gómez-Sánchez, Pilar; Rexachs, Dolores; Méndez, Sandra; Luque, Emilio (Barcelona Supercomputing Center, 2015-05-05)
      Conference report
      Open Access
      Currently, there is an increasing interest about the cloud platform by the High Performance Computing (HPC) community, and the Parallel Input/Output (I/O) for High Performance Systems is not an exception. However, in ...

    • Modelling the contact propagation of nosocomial infection in emergency departments 

      Jaramillo, Cecilia; Taboada, Manel; Epelde, Francisco; Rexachs, Dolores; Luque Amat, Emilio (Barcelona Supercomputing Center, 2015-05-05)
      Conference report
      Open Access
      The nosocomial infection is a special kind of infection that is caused by microorganisms acquired inside a hospital. In the daily care process of an emergency department, the interactions between patients and sanitary ...
