摘要

浮点运算可能会导致HPC模拟的先验相似顺序和并行执行之间的数值再现性失效。介绍了如何将现有的一些技术应用于部分水动力有限元模拟。我们分析了这些技术使我们能够很容易地恢复其数值再现性。

Numerical reproducibility: Feasibility issues

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.
