    • A computational model for progressive cracking in large dams due to the swelling of concrete 

      Cervera Ruiz, Miguel; Oliver Segura, José; Herrero, E.; Oñate Ibáñez de Navarra, Eugenio (1990-09)
      Article
      Open Access
      The paper presents a computational model for the analysis of large concrete gravity dams subjected to severe damage due to internal actions. It has been observed in several operating concrete dams that the combined effects ...

    • Accelerating SpMV on FPGAs through block-row compress: a task-based approach 

      Oliver Segura, José; Álvarez Martínez, Carlos; Cervero García, Teresa; Martorell Bofill, Xavier; Davis, John D.; Ayguadé Parra, Eduard (Institute of Electrical and Electronics Engineers (IEEE), 2023)
      Conference lecture
      Open Access
      Sparse Matrix-Vector multiplication (SpMV), computing y=α⋅A×x+β⋅y where y,x are dense vectors, α,β two scalar constants, and A is a sparse matrix, is a key kernel in many HPC applications. It exhibits a kind of memory ...

    • Applying interposition techniques for performance analysis of OPENMP parallel applications 

      González Tallada, Marc; Serra, Albert; Martorell Bofill, Xavier; Oliver Segura, José; Ayguadé Parra, Eduard; Labarta Mancho, Jesús José; Navarro, Nacho (Institute of Electrical and Electronics Engineers (IEEE), 2000)
      Conference report
      Open Access
      Tuning parallel applications requires the use of effective tools for detecting performance bottlenecks. Along a parallel program execution, many individual situations of performance degradation may arise. We believe that ...

    • Aproximació a la Supercomputació a Secundària 

      Oliver Segura, José (Universitat Politècnica de Catalunya, 2023-06-14)
      Master thesis
      Open Access
      En aquest TFM es realitza un anàlisi de les oportunitats que planteja el currículum d'educació secundària per incorporar, de manera transversal, coneixements i conceptes vinculats a la Supercomputació per tal de reduir la ...

    • Hedy Lamarr: cinema, torpedes i cintes de paper perforat 

      Oliver Segura, José (2023-03-02)
      Conference report
      Open Access
      Hedy Lamarr va ser, durant molts anys, una estrella de Hollywood, i així va passar a la posteritat. Tanmateix, Hedy Lamarr també era una inventora que no va veure reconeguda la seva aportació fins al final de la seva vida, ...

    • NanosCompiler: supporting flexible multilevel parallelism exploitation in OpenMP 

      González Tallada, Marc; Ayguadé Parra, Eduard; Martorell Bofill, Xavier; Labarta Mancho, Jesús José; Navarro, Nacho; Oliver Segura, José (2000-10)
      Article
      Restricted access - publisher's policy
      This paper describes the support provided by the NanosCompiler to nested parallelism in OpenMP. The NanosCompiler is a source-to-source parallelizing compiler implemented around a hierarchical internal program representation ...

    • New OpenMP directives for irregular data access loops 

      Labarta Mancho, Jesús José; Ayguadé Parra, Eduard; Oliver Segura, José; Henty, David (2002-03)
      Article
      Restricted access - publisher's policy
      Many scientific applications involve array operations that are sparse in nature, ie array elements depend on the values of relatively few elements of the same or another array. When parallelised in the shared-memory model, ...
