    • Parallelizing dense and banded linear algebra libraries using SMPSs 

      Badia Sala, Rosa Maria; Herrero Zaragoza, José Ramón; Labarta Mancho, Jesús José; Pérez Cáncer, Josep Maria; Quintana Ortí, Enrique Salvador; Quintana Ortí, Gregorio (2009-12-25)
      Article
      Accés restringit per política de l'editorial
      The promise of future many-core processors, with hundreds of threads running concurrently, has led the developers of linear algebra libraries to rethink their design in order to extract more parallelism, further exploit ...

    • Programming parallel dense matrix factorizations and inversion for new-generation NUMA architectures 

      Catalán Pallarés, Sandra; Igual Peña, Francisco D.; Herrero Zaragoza, José Ramón; Rodríguez Sánchez, Rafael; Quintana Ortí, Enrique Salvador (Elsevier, 2023-05)
      Article
      Accés obert
      We propose a methodology to address the programmability issues derived from the emergence of new-generation shared-memory NUMA architectures. For this purpose, we employ dense matrix factorizations and matrix inversion ...

    • Reduction to tridiagonal form for symmetric eigenproblems on asymmetric multicore processors 

      Alonso Jordá, Pedro; Catalán Pallarés, Sandra; Herrero Zaragoza, José Ramón; Quintana Ortí, Enrique Salvador; Rodríguez Sánchez, Rafael (Association for Computing Machinery (ACM), 2017)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      Asymmetric multicore processors (AMPs), as those present in ARM big.LITTLE technology, have been proposed as a means to address the end of Dennard power scaling law. The idea of these architectures is to activate only the ...

    • Reevaluación selectiva dentro del período lectivo 

      Herrero Zaragoza, José Ramón; López Álvarez, David; Mora Giné, Mercè; Sánchez Carracedo, Fermín (Universidad de Oviedo. Escuela de Ingeniería Informática, 2014-07-09)
      Text en actes de congrés
      Accés obert
      En muchos planes de estudios previos al EEES existía una segunda oportunidad para aprobar las asignaturas dentro del periodo lectivo: los exámenes de septiembre. En la actualidad, sin embargo, muchas universidades no ...

    • Static scheduling of the LU factorization with look-ahead on asymmetric multicore processors 

      Catalán Pallarés, Sandra; Herrero Zaragoza, José Ramón; Quintana Ortí, Enrique Salvador; Rodríguez Sánchez, Rafael (2018-08)
      Article
      Accés obert
      We analyze the benefits of look-ahead in the parallel execution of the LU factorization with partial pivoting (LUpp) in two distinct “asymmetric” multicore scenarios. The first one corresponds to an actual hardware-asymmetric ...

    • Static versus dynamic task scheduling of the Lu factorization on ARM big. LITTLE architectures 

      Catalán Pallarés, Sandra; Rodríguez Sánchez, Rafael; Quintana Ortí, Enrique Salvador; Herrero Zaragoza, José Ramón (Institute of Electrical and Electronics Engineers (IEEE), 2017)
      Text en actes de congrés
      Accés restringit per política de l'editorial
      We investigate several parallel algorithmic variants of the LU factorization with partial pivoting (LUpp) that trade off the exploitation of increasing levels of task-parallelism in exchange for a more cache-oblivious ...

    • Tareador: a tool to unveil parallelization strategies at undergraduate level 

      Ayguadé Parra, Eduard; Badia Sala, Rosa Maria; Jiménez González, Daniel; Herrero Zaragoza, José Ramón; Labarta Mancho, Jesús José; Subotic, Vladimir; Utrera Iglesias, Gladys Miriam (North Carolina State University, 2015)
      Text en actes de congrés
      Accés obert
      This paper presents a methodology and framework designed to assist students in the process of finding appropriate task decomposition strategies for their sequential program, as well as identifying bottlenecks ...

    • Two-sided orthogonal reductions to condensed forms on asymmetric multicore processors 

      Alonso Jordá, Pedro; Catalán Pallarés, Sandra; Herrero Zaragoza, José Ramón; Quintana Ortí, Enrique Salvador; Rodríguez Sánchez, Rafael (2018-10)
      Article
      Accés obert
      We investigate how to leverage the heterogeneous resources of an Asymmetric Multicore Processor (AMP) in order to deliver high performance in the reduction to condensed forms for the solution of dense eigenvalue and ...
