    Efficient update of determinants of rmany-electron wave function overlaps 
    Alonso-Jordá, Pedro; Davidovic, Davor; Sapunar, Marin; Herrero, Jose R.; Quintana-Ortí, Enrique S. (Elsevier, 2021-01)
    [EN] The calculation of overlaps between many-electron wave functions at different nuclear geometries during nonadiabatic dynamics simulations requires the evaluation of a large number of determinants of matrices that ...

    Exploiting nested task-parallelism in the H-LU factorization 
    Carratalá-Sáez, Rocío; Christophersen, Sven; Aliaga, José I.; Beltrán, Vicenç; Börm, Steffen; Quintana Ortí, Enrique Salvador (Elsevier, 2019-04)
    [EN] We address the parallelization of the LU factorization of hierarchical matrices (H-matrices) arising from boundary element methods. Our approach exploits task-parallelism via the OmpSs programming model and runtime, ...

    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 ...

    Some new efficient multipoint iterative methods for solving nonlinear systems of equations 
    Lotfi, T.; Bakhtiari, P.; Cordero Barbero, Alicia; Mahdiani, K.; Torregrosa Sánchez, Juan Ramón (Taylor & Francis: STM, Behavioural Science and Public Health Titles, 2015-09-02)
    It is attempted to put forward a new multipoint iterative method of sixth-order convergence for approximating solutions of nonlinear systems of equations. It requires the evaluation of two vector-function and two Jacobian ...

    Static scheduling of the LU factorization with look-ahead on asymmetric multicore processors 
    Catalán, Sandra; Herrero, José R.; Quintana Ortí, Enrique Salvador; Rodríguez-Sánchez, Rafael (Elsevier, 2018-08)
    [EN] 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 ...
