Two time Parallel algorithms for solving optimality systems
Bien que le résumé soit en anglais, le conférencier compte présenter ses travaux en français.
Time parallel algorithm is a method to solve time-dependent problems parallel in time. It divides the main problem in sub-problems in time direction and executes them in parallel to get individual outputs that are combined together to obtain the final desired solution. Because of the advent of computers with several computing cores and clusters that enable to perform many computing tasks simultaneously, the research over such algorithm has undergone particular development over the last decades. As a result, Parareal, ParaExp and many others algorithms have been developed for solving evolution problems. In this talk, we present two time parallel algorithms, the first based on Parareal and the second on ParaExp for solving an optimality system that rises from partial differential equations (PDEs) constrained optimization.
Le séminaire aura lieu au local 3820 du pavillon Alexandre-Vachon et en ligne.
