    As chip multi-processors (CMPs) are becoming more and more complex, software solutions such as parallel programming models are attracting a lot of attention. Task-based parallel programming models offer an appealing approach ...

  • vMCA: Memory Capacity Aggregation and Management in Cloud Environments 

    Garrido, Luis A.; Carpenter, Paul (IEEE, 2018-05-31)
    Comunicación de congreso
    Acceso abierto
    In cloud environments, the VMs within the computing nodes generate varying memory demand profiles. When memory utilization reaches its limits due to this, costly (virtual) disk accesses and/or VM migrations can occur. Since ...

  • Modelling multicore contention on the AURIXTM TC27x 

    Díaz, Enrique; Mezzetti, Enrico; Kosmidis, Leonidas; Abella, Jaume; Cazorla, Francisco J. (Association for Computing Machinery (ACM), 2018-06-24)
    Comunicación de congreso
    Acceso abierto
    Multicores are becoming ubiquitous in automotive. Yet, the expected benefits on integration are challenged by multicore contention concerns on timing V&V. Worst-case execution time (WCET) estimates are required as early ...

  • Measurement-based cache representativeness on multipath programs 

    Milutinovic, Suzana; Abella, Jaume; Mezzetti, Enrico; Cazorla, Francisco J. (Association for Computing Machinery (ACM), 2018-06)
    Comunicación de congreso

    Autonomous vehicles in embedded real-time systems increase critical-software size and complexity whose performance needs are covered with high-performance hardware features like caches, which however hampers obtaining WCET ...

  • Safe Parallelism: Compiler Analysis Techniques for Ada and OpenMP 

    Royuela, Sara; Martorell, Xavier; Quiñones, Eduardo; Pinho, Luis Miguel (Springer Verlag, 2018-05-26)
    Comunicación de congreso
    Acceso abierto
    There is a growing need to support parallel computation in Ada to cope with the performance requirements of the most advanced functionalities of safety-critical systems. In that regard, the use of parallel programming ...

  • Accelerating K-mer Frequency Counting with GPU and Non-Volatile Memory 

    Cadenelli, Nicola; Polo, Jordà; Carrera, David (IEEE, 2018-02-15)
    Comunicación de congreso
    Acceso abierto
    The emergence of Next Generation Sequencing (NGS) platforms has increased the throughput of genomic sequencing and in turn the amount of data that needs to be processed, requiring highly efficient computation for its ...

  • Cache side-channel attacks and time-predictability in high-performance critical real-time systems 

    Trilla, David; Hernandez, Carles; Abella, Jaume; Cazorla, Francisco J. (Association for Computing Machinery (ACM), 2018-06-24)
    Comunicación de congreso
    Acceso abierto
    Embedded computers control an increasing number of systems directly interacting with humans, while also manage more and more personal or sensitive information. As a result, both safety and security are becoming ubiquitous ...

  • Response-time analysis of DAG tasks supporting heterogeneous computing 

    Serrano, Maria A.; Quiñones, Eduardo (Association for Computing Machinery (ACM), 2018-06-24)

  • Work-in-Progress Paper: An Analysis of the Impact of Dependencies on Probabilistic Timing Analysis and Task Scheduling 

    Mezzetti, Enrico; Abella, Jaume; Hernandez, Carles; Cazorla, Francisco J. (IEEE, 2018-02-01)
    Comunicación de congreso
    Acceso abierto
    Recently there has been a renewed interest for probabilistic timing analysis (PTA) and probabilistic task scheduling (PTS). Despite the number of works in both fields, the link between them is weak: works on the latter ...

  • Design and integration of hierarchical-placement multi-level caches for real-time systems 

    Benedicte, Pedro; Hernandez, Carles; Abella, Jaume; Cazorla, Francisco J. (IEEE, 2018-04-23)
    Comunicación de congreso
    Acceso abierto
    Enabling timing analysis in the presence of caches has been pursued by the real-time embedded systems (RTES) community for years due to cache's huge potential to reduce software's worst-case execution time (WCET). However, ...

  • dReDBox: Materializing a full-stack rack-scale system prototype of a next-generation disaggregated datacenter 

    Bielski, M.; Syrigos, I.; Katrinis, K.; Syrivelis, D.; Reale, A.; Theodoropoulos, D.; Alachiotis, N.; Pnevmatikatos, D.; Pap, E.H.; Zervas, G.; Mishra, V.; Saljoghei, A.; Rigo, A.; Fernando Zazo, J.; Lopez-Buedo, S.; Torrents, Marti; Zyulkyarov, Ferad Hasanov; Enrico, M.; Gonzalez de Dios, O.
