Short summary
In this paper, we show that different compiling setups can achieve exactly the same (bitwise identical) results in Earth system modeling, and a set of bitwise identical compiling setups of a model can be used across different compiler versions and different compiler flags. Moreover, we shows that new test cases can be generated based on differences of bitwise identical compiling setups between different models, which can help detect software bugs and finally improve the reliability.
