论文摘要
沙丘与其他HEP实验一样，面临与现代高性能计算设施所施加的限制的匹配执行模式有关的挑战。为了有效利用这些新架构，尤其是CPU核心计数和GPU加速器的架构，我们现有的软件执行模型需要适应。此外，来自远处检测器模块的大量原始数据的大尺寸单位构成了Dune在某种程度上独有的额外挑战。在这里，我们描述了其中一些问题，以及我们今天如何使用现有的软件框架和工具包开始解决这些问题。我们还描述了可以利用这些现有软件体系结构来攻击剩余问题的方式。该白皮书是Snowmass21的计算前沿的贡献。
DUNE, like other HEP experiments, faces a challenge related to matching execution patterns of our production simulation and data processing software to the limitations imposed by modern high-performance computing facilities. In order to efficiently exploit these new architectures, particularly those with high CPU core counts and GPU accelerators, our existing software execution models require adaptation. In addition, the large size of individual units of raw data from the far detector modules pose an additional challenge somewhat unique to DUNE. Here we describe some of these problems and how we begin to solve them today with existing software frameworks and toolkits. We also describe ways we may leverage these existing software architectures to attack remaining problems going forward. This whitepaper is a contribution to the Computational Frontier of Snowmass21.
