    Compact quasi-Newton preconditioners for symmetric positive definite linear systems 
    BERGAMASCHI, LUCA; Marín Mateos-Aparicio, José; MARTINEZ, ANGELES (John Wiley & Sons, 2020-12)
    [EN] In this paper, preconditioners for the conjugate gradient method are studied to solve the Newton system with symmetric positive definite Jacobian. In particular, we define a sequence of preconditioners built by means ...

    Toward a modular precision ecosystem for high performance computing 
    Anzt, Hartwig; Flegar, Goran; Gruetzmacher, Thomas; Quintana-Orti, Enrique S. (SAGE Publications, 2019-11)
    [EN] With the memory bandwidth of current computer architectures being significantly slower than the (floating point) arithmetic performance, many scientific computations only leverage a fraction of the computational power ...
