1 Motivation of Time Decomposition in the Parallel CFD context

Time domain decomposition methods can bo a complementary approach to improve parallelism on the forthcoming parallel architectures with thousand of processors. Indeed. for a given modelled problem. e.g. through a partial differential equation with a prescribed discretization- the multiplication of the processors leads to a decrease of the computing load allocated to each processors, then the ratio of the computing time with the communication time decreases, ...
