论文摘要
原子质模型(OpenKIM)项目的开放知识库是一个框架,旨在促进分子模拟的原子间模型的标准化实现以及计算协议以评估它们。这些协议包括测试以计算模型预测的材料属性和验证检查以评估其编码完整性。在统一的,公开可用的环境中将这些内容构成,这是分子建模社区的重要一步,但它进一步提供了了解原子间模型的有效性范围及其对特定目标应用的适用性的机会。为此,OpenKim包括一个计算管道,该计算管道使用OpenKim存储库中包含的所有可用的原子质模型运行测试和验证检查,网址为https://openkim.org。 OpenKim处理管道建立在托管在分布式,异质硬件上的一组Docker图像上,并利用开源软件自动运行测试模型和验证检查模型对并解决它们之间的依赖关系。讨论了在管道开发中做出的设计理念和实施选择,以及其在原子间模型选择中的应用的示例。
The Open Knowledgebase of Interatomic Models (OpenKIM) project is a framework intended to facilitate access to standardized implementations of interatomic models for molecular simulations along with computational protocols to evaluate them. These protocols includes tests to compute materials properties predicted by models and verification checks to assess their coding integrity. While housing this content in a unified, publicly available environment constitutes a major step forward for the molecular modeling community, it further presents the opportunity to understand the range of validity of interatomic models and their suitability for specific target applications. To this end, OpenKIM includes a computational pipeline that runs tests and verification checks using all available interatomic models contained within the OpenKIM Repository at https://openkim.org. The OpenKIM Processing Pipeline is built on a set of Docker images hosted on distributed, heterogeneous hardware and utilizes open-source software to automatically run test-model and verification check-model pairs and resolve dependencies between them. The design philosophy and implementation choices made in the development of the pipeline are discussed as well as an example of its application to interatomic model selection.
