A highly parallel algorithm for computing the action of a matrix exponential on a vector based on a multilevel Monte Carlo method
(2020-01-01)
Article
Accés obertA novel algorithm for computing the action of a matrix exponential over a vector is proposed. The algorithm is based on a multilevel Monte Carlo method, and the vector solution is computed probabilistically generating ... -
Exponential versus IMEX high-order time integrators for thermal convection in rotating spherical shells
(2014-01-24)
Article
Accés obertWe assess the accuracy and efficiency of several exponential time integration methods coupled to a spectral discretization of the three-dimensional Boussinesq thermal convection equations in rotating spherical shells. ...
