Dans le cadre de l’équipe associée FASTLA du programme Inria@SV, Eric Darve (professeur à Stanford) visitera le centre du 16 au 18 Juillet.
Il fera un séminaire intitulé “Fast direct linear solvers” le mercredi 16 Juillet à 14h – salle Ada Lovelace
- Eric Darve (Stanford University): Fast direct linear solvers
In recent years there has been a resurgence in direct methods to solve linear systems. These methods can have many advantages compared to iterative solvers; in particular their accuracy and performance is less sensitive to the distribution of eigenvalues. However, they typically have a larger computational cost in cases where iterative solvers converge in few iterations. We will discuss a recent trend of methods that address this cost and can make these direct solvers competitive. Techniques involved include hierarchical matrices, hierarchically semi-separable matrices, fast multipole method, etc.
