Abstract : Floating-point arithmetic may introduce failures of the numerical reproducibility between a priori similar sequential and parallel executions of HPC simulation. We present how to apply some existing techniques to part of hydrodynamic finite element simulations. We analyze how easy these techniques allow us to recover its numerical reproducibility.
