    The high-performance computing (HPC) community has recently started to use containerization to obtain fast, customized, portable, flexible, and reproducible deployments of their workloads. Previous work showed that deploying ...
  • Hints to improve automatic load balancing with LeWI for hybrid applications 

    Garcia Gasulla, Marta; Labarta Mancho, Jesús José; Corbalán González, Julita (Elsevier, 2014-09-01)
    Article
    Open Access
    The DLB (Dynamic Load Balancing) library and LeWl (LEnd When Idle) algorithm provide a runtime solution to deal with the load imbalance of parallel applications independently of the source of imbalance. DLB relies on the ...
  • Embedding reactive behavior into artifact-centric business process models 

    Oriol Hilari, Xavier; Giacomo, Giuseppe De; Estañol Lamarca, Montserrat; Teniente López, Ernest (Elsevier, 2021-04-01)
    Article

    In artifact-centric business process models it is usually assumed that the specification of the activities requires stating all the effects of the activity execution over the information base (i.e. over the artifacts it ...
  • A RISC-V simulator and benchmark suite for designing and evaluating vector architectures 

    Ramírez Lazo, Cristóbal; Hernández, César Alejandro; Palomar Pérez, Óscar; Unsal, Osman Sabri; Ramírez Salinas, Marco Antonio; Cristal Kestelman, Adrián (2020-11)
    Article
    Open Access
    Vector architectures lack tools for research. Consider the gem5 simulator, which is possibly the leading platform for computer-system architecture research. Unfortunately, gem5 does not have an available distribution that ...
  • Multi-core devices for safety-critical systems: a survey 

    Perez Cerrolaza, Jon; Obermaisser, Roman; Abella Ferrer, Jaume; Cazorla Almeida, Francisco Javier; Grüttner, Kim; Agirre, Irune; Ahmadian, Hamidreza; Allende, Imanol (Association for Computing Machinery (ACM), 2020-09)
    Article
    Open Access
    Multi-core devices are envisioned to support the development of next-generation safety-critical systems, enabling the on-chip integration of functions of different criticality. This integration provides multiple system-level ...
  • HDOT — An approach towards productive programming of hybrid applications 

    Ciesko, Jan; Martínez Ferrer, Pedro Jose; Peñacoba Veigas, Raúl; Teruel García, Xavier; Beltran, Vicenç; Ciesko (Elsevier, 2020-03)
    Article

    bulk synchronous parallel (BSP) communication model can hinder performance increases. This is due to the complexity to handle load imbalances, to reduce serialisation imposed by blocking communication patterns, to overlap ...
  • 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
    Restricted access - publisher's policy
    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 ...
