    D'Amico, Marco; Corbalán González, Julita (2021-06-17)
    Article
    Accés obert
    New HPC machines are getting close to the exascale. Power consumption for those machines has been increasing, and researchers are studying ways to reduce it. A second trend is HPC machines' growing complexity, with increasing ...
  • Charging of the ABR service in ATM networks: a numerical example 

    Cerdà Alabern, Llorenç; Casals Torres, Olga M. (Institute of Electrical and Electronics Engineers (IEEE), 1998-04)
    Article
    Accés obert
    The Available Bit Rate service (ABR) is a "best effort" service intended for traffic which imposes no bound on delay or delay variation. The network guarantees a Minimum Cell Rate (MCR) for an ABR source, which is negotiated ...
  • O(n) key–value sort with active compute memory 

    Esmaili Dokht, Pouya; Guiot Cusido, Miquel; Radojkovic, Petar; Martorell Bofill, Xavier; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Adlard, Jason; Amato, Paolo; Sforzin, Marco (Institute of Electrical and Electronics Engineers (IEEE), 2024-02-29)
    Article
    Accés obert
    We propose the Active Compute Memory (ACM), a near-memory-processing architecture capable of performing key–value sort directly in the DRAM. In the ACM architecture, sort is merely the writing of data into memory with one ...
  • Abisko: Deep codesign of an architecture for spiking neural networks using novel neuromorphic materials 

    Vetter, Jeffrey; Date, Prasanna; Fahim, Farah; Kulkarni, Shruti R.; Maksymovych, Petro; Talin, Alec; González Tallada, Marc; Vanna Iampikul, Pruek; Young, Aaron Reed; Brooks, David (SAGE publishing, 2023-07)
    Article
    Accés obert
    The Abisko project aims to develop an energy-efficient spiking neural network (SNN) computing architecture and software system capable of autonomous learning and operation. The SNN architecture explores novel neuromorphic ...
  • Finding, analysing and solving MPI communication bottlenecks in Earth System models 

    Tintó Prims, Oriol; Castrillo Melguizo, Miguel; Acosta Cobos, Mario César; Mula Valls, Josep Oriol; Sánchez Lorente, Alícia; Serradell Maronda, Kim; Cortés Fité, Ana; Doblas Reyes, Francisco (Elsevier, 2019-09)
    Article
    Accés obert
    It is a matter of consensus that the ability to efficiently use current and future high performance computing systems is crucial for science, however, the reality is that the performance currently achieved by most of the ...
  • Perpetual reconfigurable intelligent surfaces through in-band energy harvesting: architectures, protocols, and challenges 

    Ntontin, Konstantinos; Boulogeorgos, Alexandros Apostolos A.; Abadal Cavallé, Sergi; Mesodiakaki, Agapi; Chatzinotas, Symeon; Ottersten, Björn (Institute of Electrical and Electronics Engineers (IEEE), 2024-01-05)
    Article
    Accés obert
    Reconfigurable intelligent surfaces (RISs) are considered a key enabler of highly energy-efficient 6G and beyond networks. This property arises from the absence of power amplifiers in the structure, in contrast to active ...
  • The effects of weight quantization on online federated learning for the IoT: a case study 

    Llisterri Giménez, Nil; Lee, Junkyu; Freitag, Fèlix; Vandierendonck, Hans (Institute of Electrical and Electronics Engineers (IEEE), 2024-01-04)
    Article
    Accés obert
    Many weight quantization approaches were explored to save the communication bandwidth between the clients and the server in federated learning using high-end computing machines. However, there is a lack of weight quantization ...
  • The MAMe dataset: On the relevance of high resolution and variable shape image properties 

    Parés Pont, Ferran; Arias Duart, Anna; García Gasulla, Dario; Campo Francés, Gema; Viladrich Iglesias, Nina; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José (Springer, 2022-08)
    Article
    Accés obert
    The mostcommon approach in image classification tasks is to resize all images in the dataset to a unique shape, while reducing their resolution to a size that makes experimentation at scale easier. This practice has benefits ...
  • ATC human factors involved in RPAS contingency management in non-segregated airspace 

    Reyes Muñoz, María Angélica; Barrado Muxí, Cristina; Pastor Llorens, Enric; Royo Chic, Pablo (Multidisciplinary Digital Publishing Institute, 2023-01-20)
    Article
    Accés obert
    The overall approach towards Remotely Piloted Aerial System integration into a non-segregated airspace is that the unmanned vehicles should be able to fit into the current air traffic management system, thus meeting all ...
  • Assistive self-driving car networks to provide safe road ecosystems for disabled road users
