Towards an efficient Task-based Parallelization over a Runtime System of an Explicit Finite-Volume CFD Code with Adaptive Time Stepping
Abstract : FLUSEPA is an advanced simulation tool which performs a large panel of aerodynamic studies. It is the unstruc-tured finite-volume solver developed by Airbus Defence & Space company to calculate compressible, multidimensional, unsteady, viscous and reactive flows around bodies in relative motion. The time integration in FLUSEPA is done using an explicit temporal adaptive method. The current production version of the code is based on MPI and OpenMP. This implementation leads to important synchronizations that must be reduced. To tackle this problem, we present a first study of a task-based parallelization of the solver part of FLUSEPA using the runtime system StarPU and combining up to three levels of parallelism. We validate our solution on the simulation of a takeoff blast wave propagation for Ariane 5 launcher.
