Exploiting Two-Level Parallelism in FEM Applications

In this paper we present a parallel algorithm for solving the Euler equations on unstructured grids. Time discretization is organized with a linear, implicit version of Taylor-Galerkin time scheme, while finite elements are employed for space discretization of one step problem.
