Abstract : The lack of numerical reproducibility for parallel floating-point computations is a stringent problem for HPC numerical simulations. Reproducibility is indeed desirable for code verification, testing,debugging and even for certification authority agreement. We describe and analyse strategies towards numerically reproducible simulations with a well known open source software for computational fluid dynamics.
