Query: Design and Analysis of a Task-based Parallelization over a Runtime
  System of an Explicit Finite-Volume CFD Code with Adaptive Time Stepping   FLUSEPA (Registered trademark in France No. 134009261) is an advanced
simulation tool which performs a large panel of aerodynamic studies. It is the
unstructured finite-volume solver developed by Airbus Safran Launchers 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 the
study of a task-based parallelization of the aerodynamic solver of FLUSEPA
using the runtime system StarPU and combining up to three levels of
parallelism. We validate our solution by the simulation (using a finite-volume
mesh with 80 million cells) of a take-off blast wave propagation for Ariane 5
launcher.
