  • Benefits of a Fog-to-Cloud Approach in Proximity Marketing 

    Salis, Antonio; Mancini, Glauco; Bulla, Roberto; Cocco, Paolo; Lezzi, Daniele; Lordan, Francesc (Springer, 2018-12-31)
    Conference lecture
    Open Access
    The EC H2020 mF2C Project is working to the development of a software framework that enables the orchestration of resources and communication at fog level, as an extension of cloud computing and interacting with the IoT. ...
  • On assessing the viability of probabilistic scheduling with dependent tasks 

    Abella, Jaume; Mezzetti, Enrico; Cazorla, Francisco J. (Association for Computing Machinery (ACM), 2019-04-08)
    Conference lecture
    Open Access
    Despite the significant interest, in the last years, in probabilistic scheduling and probabilistic timing analysis, the interrelation between them has been scarcely addressed. Probabilistic scheduling approaches typically ...
  • Performance Study of Non-volatile Memories on a High-End Supercomputer 

    Bautista-Gomez, Leonardo; Keller, Kai; Unsal, Osman (2019-01-25)
    Part of book or chapter of book
    Open Access
    The first exa-scale supercomputers are expected to be operational in China, USA, Japan and Europe within the early 2020’s. This allows scientists to execute applications at extreme scale with more than 1018 floating point ...
  • Teaching HPC systems and parallel programming with small-scale clusters 

    Álvarez Martí, Lluc; Ayguadé Parra, Eduard; Mantovani, Filippo
    Conference report
    Restricted access - publisher's policy
    In the last decades, the continuous proliferation of High-Performance Computing (HPC) systems and data centers has augmented the demand for expert HPC system designers, administrators, and programmers. For this reason, ...
  • On the Resilience of RTL NN Accelerators: Fault Characterization and Mitigation 

    Salami, Behzad; Unsal, Osman S.; Cristal, Adrian (IEEE, 2019-02-21)
    Conference lecture
    Open Access
    Machine Learning (ML) is making a strong resurgence in tune with the massive generation of unstructured data which in turn requires massive computational resources. Due to the inherently compute and power-intensive structure ...
  • A Demo of FPGA Aggressive Voltage Downscaling: Power and Reliability Tradeoffs 

    Salami, Behzad; Unsal, Osman; Cristal, Adrian (IEEE, 2018-12-06)
    Conference lecture
    Open Access
    The power consumption of digital circuits, e.g., Field Programmable Gate Arrays (FPGAs), is directly related to their operating supply voltages. On the other hand, usually, chip vendors introduce a conservative voltage ...
  • Fault Characterization Through FPGA Undervolting 

    Salami, Behzad; Unsal, Osman S.; Cristal, Adrian (IEEE, 2018-12-06)
    Conference lecture
    Open Access
    The power and energy efficiency of Field Programmable Gate Arrays (FPGAs) are estimated to be up to 20X less than Application Specific Integrated Circuits (ASICs). What is needed to close this gap is aggressive power/energy ...
  • Comprehensive Evaluation of Supply Voltage Underscaling in FPGA on-Chip Memories 

    Salami, Behzad; Unsal, Osman S.; Cristal, Adrian (IEEE, 2018-12-13)
    Conference lecture
    Open Access
    In this work, we evaluate aggressive undervolting, i.e., voltage scaling below the nominal level to reduce the energy consumption of Field Programmable Gate Arrays (FPGAs). Usually, voltage guardbands are added by chip ...
  • On the Applicability of PEBS based Online Memory Access Tracking for Heterogeneous Memory Management at Scale 

    Roca Nonell, Aleix; Gerofi, Balazs; Bautista-Gomez, Leonardo; Martinet, Dominique; Beltran, Vicenç; Ishikawa, Yutaka (Association for Computing Machinery (ACM), 2018-11)
    Conference lecture
    Open Access
    Operating systems have historically had to manage only a single type of memory device. The imminent availability of heterogeneous memory devices based on emerging memory technologies confronts the classic single memory ...
  • Multi-tenant Pub/Sub Processing for Real-Time Data Streams 

    Villalba, Álvaro; Carrera, David (Springer, 2018-12)
    Conference lecture
    Open Access
    Devices and sensors generate streams of data across a diversity of locations and protocols. That data usually reaches a central platform that is used to store and process the streams. Processing can be done in real time, ...
  • Disaggregating Non-Volatile Memory for Throughput-Oriented Genomics Workloads 

    Call, Aaron; Polo, Jordà; Carrera, David; Guim, Francesc; Sen, Sujoy (Springer, 2018-12)
    Conference lecture
    Open Access
    Massive exploitation of next-generation sequencing technologies requires dealing with both: huge amounts of data and complex bioinformatics pipelines. Computing architectures have evolved to deal with these problems, ...
  • MPI+OpenMP tasking scalability for the simulation of the human brain 

    Valero-Lara, Pedro; Sirvent, Raul; Pena, A. J.; Martorell Bofill, Xavier; Labarta Mancho, Jesús José (Association for Computing Machinery (ACM), 2018)
    Conference report
    Open Access
    The simulation of the behavior of the Human Brain is one of the most ambitious challenges today with a non-end of important applications. We can find many different initiatives in the USA, Europe and Japan which attempt ...
