Conclusion: With OpenACC, we find that the instance of fluid dynamics process for molten salt reactor is given out using the GPU version of Code_Saturne and the performance of the GPU version of Code_Saturne can be enhanced compared with that of the CPU version. Results: From the result of the implementation of the GPU-parallel code, it is manifested that the empirical tuning of OpenACC accelerated code sections are valid for obtaining correct results, and enhancing performance and portability. Finally, the parallel implementation and general optimization strategies to the OpenACC version of Code_Saturne were tested and validated on a simplified molten salt reactor. And the preconditioned conjugate gradients for solving linear equations were implemented on the GPU. Methods: OpenACC directives were used as the main programming model to speed up the vector and matrix linear operation. Purpose: This study aims to achieve graphics processing unit (GPU) parallelization of fluid dynamics process of molten salt reactor core. Abstract: Background: The simulation of fluid dynamics process for molten salt reactor proposes a large compute complexity, which requires high performance computer systems to enhance speed and efficiency.
