El producto matricial distribuido en entornos computacionales de alto rendimiento

Huerta Gañán, Rodrigo (Universitat Politècnica de València, 2020-09-08)

[ES] La multiplicación de matrices es una operación fundamental para la resolución de innumerables problemas matemáticos que tienen a esta operación en su base. El coste de esta operación, incluso el algoritmo utilizado, ...
Hierarchical approach for deriving a reproducible unblocked LU factorization

Iakymchuk, Roman; Graillat, Stef; Defour, David; Quintana-Orti, Enrique S. (SAGE Publications, 2019-09)

[EN] We propose a reproducible variant of the unblocked LU factorization for graphics processor units (GPUs). For this purpose, we build upon Level-1/2 BLAS kernels that deliver correctly-rounded and reproducible results ...
Integration and exploitation of intra-routine malleability in BLIS

Rodríguez-Sánchez, Rafael; Igual, Francisco D.; Quintana-Ortí, Enrique S. (Springer-Verlag, 2020-04)

[EN] Malleability is a property of certain applications (or tasks) that, given an external request or autonomously, can accommodate a dynamic modification of the degree of parallelism being exploited at runtime. Malleability ...
Multi-threaded dense linear algebra libraries for low-power asymmetric multicore processors

Catalán, Sandra; Herrero, José R.; Igual Peña, Francisco Daniel; Rodríguez-Sánchez, Rafael; Quintana Ortí, Enrique Salvador; Adeniyi-Jones, Chris (Elsevier, 2018-03)

[EN] Dense linear algebra libraries, such as BLAS and LAPACK, provide a relevant collection of numerical tools for many scientific and engineering applications. While there exist high performance implementations of the ...
Solving initial value problems for ordinary differential equations by two approaches: BDF and Piecewise-linearized methods

Ibáñez González, Jacinto Javier; Hernández García, Vicente; Arias, E.; Ruiz Martínez, Pedro Antonio (Elsevier, 2009-05)

Many scientific and engineering problems are described using Ordinary Differential Equations (ODEs), where the analytic solution is unknown. Much research has been done by the scientific community on developing numerical ...
