    The fast-paced evolution of cyberattacks to digital infrastructures requires new protection mechanisms to counter-attack them. Malware attacks, a type of cyberattacks ranging from viruses and worms to ransomware and spyware, ...

  • LIBRA: memory bandwidth- and locality-aware parallel tile rendering 

    Tomás Berjaga, Aurora; Aragón Alcaraz, Juan Luis; Parcerisa Bundó, Joan Manuel; González Colás, Antonio María (Institute of Electrical and Electronics Engineers (IEEE), 2024)
    Conference report
    Open Access
    The increasing demand for high-quality graphics requires a significant increase in computational power of modern GPUs. The common approach to follow is augmenting the number of compute units (i.e., shader cores). However, ...

  • Bias reduction via cooperative bargaining in synthetic graph dataset generation 

    Wassington, Axel; Abadal Cavallé, Sergi (2025)
    Article
    Restricted access - publisher's policy
    In general, to draw robust conclusions from a dataset, all the analyzed population must be represented on said dataset. Having a dataset that does not fulfill this condition normally leads to selection bias. This problem ...

  • Tailoring graph neural network-based flow-guided localization to individual bloodstreams and activities 

    Galván Calderón, Pablo José; Abadal Cavallé, Sergi; Lemic, Filip; Calvo Bartra, Gerard; Costa Pérez, Xavier (Association for Computing Machinery (ACM), 2024)
    Conference report
    Open Access
    Flow-guided localization using in-body nanodevices in the bloodstream is expected to be beneficial for early disease detection, continuous monitoring of biological conditions, and targeted treatment. The nanodevices face ...
