在大多数研究领域，结果的可重复性是对实验结果的强大要求，称为科学。对于使用高性能计算（HPC）获得的模拟软件获得的结果，这将转化为代码质量要求。尽管有许多专注于软件质量的作品，但通常不会考虑HPC科学仿真软件的特殊性。本文提出了一种在HPC科学模拟软件中介绍质量程序的方法，同时保持侵入性较小，以减轻其采用。该方法依赖于质量程序，包括人类法规审查和自动测试，并提供专门的程序来帮助以这种方式找到正确的缺陷。这些程序集成到旨在提高缺陷的可追溯性的开发工作流中。通过为制定Gysela代码的制定实施这种方法，我们表明它确实是可行的，并且投资回报率是积极的。我们还确定了针对本实验开发的多个可重复使用的要素，这些要素应降低采用其他代码方法的成本以及一些仍然可以改进的方面，以确保社区中该方法的广泛传播。
Reproducibility of results is a strong requirement in most fields of research for experimental results to be called science. For results obtained through simulation software using high performance computing (HPC) this translates as code quality requirements. While there are many works focusing on software quality, these typically do not take the specificities of HPC scientific simulation software into account. This paper presents an approach to introduce quality procedures in HPC scientific simulation software while remaining the less invasive as possible so as to ease its adoption. The approach relies on quality procedures including human code review and automated testing and offers a dedicated procedure to help correct defects found this way. These procedures are integrated in a development work-flow designed to improve the traceability of defects. By implementing this approach for the development of the Gysela code, we show that it is indeed viable and that the return on investment is positive. We also identify multiple reusable elements developed for this experiment that should reduce the cost of adopting the approach for other codes as well as some aspects that can still be improved to ensure a widespread propagation of the approach in the community.
