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 AccessThe 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 AccessSparse 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 AccessTuning 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 AccessEn 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 AccessHedy 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 policyThis 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 policyMany 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, ...
