A differential privacy protection-based federated deep learning framework to fog-embedded architectures
Gutiérrez Escobar, Norma; Otero Calviño, Beatriz; Rodríguez Luna, Eva; Utrera Iglesias, Gladys Miriam; Mus León, Sergi; Canal Corretger, Ramon (Elsevier, 2024-04)
Article
Accés obertNowadays, companies collect massive quantities of data to enhance their operations, often at the expense of sharing user sensible information. This data is widely used to train Deep Learning (DL) neural networks to model, ... -
A methodology approach to compare performance of parallel programming models for shared-memory architectures
Utrera Iglesias, Gladys Miriam; Gil, Marisa; Martorell Bofill, Xavier (Springer, 2020)
Capítol de llibre
Accés obertThe majority of current HPC applications are composed of complex and irregular data structures that involve techniques such as linear algebra, graph algorithms, and resource management, for which new platforms with varying ... -
Analyzing the impact of communication imbalance in high-speed networks
Utrera Iglesias, Gladys Miriam; Gil, Marisa; Martorell Bofill, Xavier (2017-12-21)
Article
Accés obertIn this work we analyze the communication load imbalance generated by irregular-data applications running in a multi-node cluster. Experimental approaches to diminish communication load imbalance are evaluated using a ... -
Analyzing the performance of hierarchical collective algorithms on ARM-based multicore clusters
Utrera Iglesias, Gladys Miriam; Gil, Marisa; Martorell Bofill, Xavier (Institute of Electrical and Electronics Engineers (IEEE), 2022)
Comunicació de congrés
Accés obertMPI is the de facto communication standard library for parallel applications in distributed memory architectures. Collective operations performance is critical in HPC applications as they can become the bottleneck of their ... -

Mapping parallel loops on multicore systems
Tabik, Siham; Romero, Felipe; Utrera Iglesias, Gladys Miriam; Plata, Oscar (2010)
Text en actes de congrés
Accés obertThe compute nodes in contemporary HPC systems contain one or more multicore processors. As a result, these nodes constitute a shared-memory multiprocessor, often combining CMP and SMT concurrency technologies. This ... -
Noise inspector tool
Utrera Iglesias, Gladys Miriam; Fornés de Juan, Jordi; Labarta Mancho, Jesús José (Institute of Electrical and Electronics Engineers (IEEE), 2017)
Text en actes de congrés
Accés obertThe operating system noise can interfere with normal execution programs. This behavior is becoming especially important when scaling parallel programs and amplified with global synchronizations. This work presents a tool ... -
OpenCAL++: An object-oriented architecture for transparent parallel execution of cellular automata models
Giordano, Andrea; D'Ambrosio, Donato; Macri, Davide; Rongo, Rocco; Utrera Iglesias, Gladys Miriam; Gil, Marisa; Spataro, William (Institute of Electrical and Electronics Engineers (IEEE), 2023)
Text en actes de congrés
Accés obertCellular Automata (CA) models, initially studied by John von Neumann, have been developed by numerous researchers and applied in both academic and scientific fields. Thanks to their local and independent rules, simulations ... -
