    • A Modular Framework for Generic Quantum Algorithms 

      Manzano, Alberto; Musso, Daniele; Leitao, Álvaro; Gómez, Andrés; Vázquez, Carlos; Ordóñez, Gustavo; Rodríguez Nogueiras, María (MDPI, 2022)
      [Abstract] We describe a general-purpose framework to design quantum algorithms. This framework relies on two pillars: a basic data structure called quantum matrix and a modular structure based on three quasi-independent ...
    • Enhanced global optimization methods applied to complex fisheries stock assessment models 

      Penas, David R.; Gómez, Andrés; Fraguela, Basilio B.; Martín, María J.; Cerviño, Santiago (Elsevier BV, 2019-04)
      [Abstract] Statistical fisheries models are frequently used by researchers and agencies to understand the behavior of marine ecosystems or to estimate the maximum acceptable catch of different species of commercial interest. ...
    • Novel parallelization of simulated annealing and Hooke & Jeeves search algorithms for multicore systems with application to complex fisheries stock assessment models 

      Vázquez Pardo, Sergio; Martín, María J.; Fraguela, Basilio B.; Gómez, Andrés; Rodríguez, Aurelio; Elvarsson, Bjarki Þór (Elsevier Ltd, 2016-11)
      [Abstract] Estimating parameters of a statistical fisheries assessment model typically involves a comparison of disparate datasets to a forward simulation model through a likelihood function. In all but trivial cases the ...
    • Performance Evaluation of MPI, UPC and OpenMP on Multicore Architectures 

      Mallón, Damián A.; López Taboada, Guillermo; Teijeiro Barjas, Carlos; Touriño, Juan; Fraguela, Basilio B.; Gómez, Andrés; Doallo, Ramón; Mouriño, José C. (Springer, 2009)
      [Abstract] The current trend to multicore architectures underscores the need of parallelism. While new languages and alternatives for supporting more efficiently these systems are proposed, MPI faces this new challenge. ...
    • Performance Evaluation of Unified Parallel C Collective Communications 

      López Taboada, Guillermo; Teijeiro Barjas, Carlos; Touriño, Juan; Fraguela, Basilio B.; Doallo, Ramón; Mouriño, José C.; Mallón, Damián A.; Gómez, Andrés (IEEE Computer Society, 2009-07-17)
      [Abstract] Unified Parallel C (UPC) is an extension of ANSI C designed for parallel programming. UPC collective primitives, which are part of the UPC standard, increase programming productivity while reducing the communication ...
    • Quantum Arithmetic for Directly Embedded Arrays 

      Manzano, Alberto; Musso, Daniele; Leitao, Álvaro; Gómez, Andrés; Vázquez, Carlos; Ordóñez, Gustavo; Rodríguez Nogueiras, María (MDPI, 2021)
      [Abstract] We describe a general-purpose framework to implement quantum algorithms relying upon an efficient handling of arrays. The cornerstone of the framework is the direct embedding of information into quantum amplitudes, ...
    • Scalable PGAS collective operations in NUMA clusters 

      Mallón, Damián A.; Teijeiro Barjas, Carlos; González-Domínguez, Jorge; López Taboada, Guillermo; Gómez, Andrés (Springer New York LLC, 2014-12)
      [Abstract] The increasing number of cores per processor is turning manycore-based systems in pervasive. This involves dealing with multiple levels of memory in non uniform memory access (NUMA) systems and processor cores ...
