Efficient parallel resolution of the simplified transport equations in mixed-dual formulation (Q630443)

In the present article, based on the simplified transport equations is obtained a high parallel efficiency while improving the parallelization scheme of the Lagrangian domain decomposition method applied to the sequential power algorithm made of four nested loops. First, the authors change the location of the loop over the subdomains to obtain the same number of power iterations as the sequential algorithm. Secondly, the authors benefit from the characteristics of the Raviart-Thomas finite element to optimize the implementation of the new parallel algorithm.
