Abstract

This study introduces chopin, an R package that lowers the technical barriers to parallelizing geocomputation. Supporting popular R spatial-analysis libraries, chopin exploits parallel computing by partitioning data involved in each task. Partitioning can occur with regular grids, hierarchical units, or multiple file inputs, accommodating diverse input types and ensuring interoperability. This approach scales geospatial covariate calculations to match available processing power, from laptop computers to high-performance computers, reducing execution times proportional to the number of processing units. chopin is expected to benefit a broad range of research communities working with large-scale geospatial data, providing an efficient, flexible, and accessible tool for scaling geospatial computations.

Chopin：一个开源的r语言工具，支持在可并行基础设施上进行空间分析

本研究介绍了chopin，一个R包，降低了并行地理计算的技术障碍。支持流行的R空间分析库，chopin通过划分每个任务中涉及的数据来利用并行计算。可以使用规则网格、分层单元或多个文件输入进行分区，以适应不同的输入类型并确保互操作性。这种方法扩展地理空间协变量计算，以匹配从笔记本电脑到高性能计算机的可用处理能力，减少与处理单元数量成比例的执行时间。肖邦有望使广泛的研究团体受益于大规模地理空间数据，为缩放地理空间计算提供高效、灵活和可访问的工具。

期刊介绍： SoftwareX aims to acknowledge the impact of software on today''s research practice, and on new scientific discoveries in almost all research domains. SoftwareX also aims to stress the importance of the software developers who are, in part, responsible for this impact. To this end, SoftwareX aims to support publication of research software in such a way that: The software is given a stamp of scientific relevance, and provided with a peer-reviewed recognition of scientific impact; The software developers are given the credits they deserve; The software is citable, allowing traditional metrics of scientific excellence to apply; The academic career paths of software developers are supported rather than hindered; The software is publicly available for inspection, validation, and re-use. Above all, SoftwareX aims to inform researchers about software applications, tools and libraries with a (proven) potential to impact the process of scientific discovery in various domains. The journal is multidisciplinary and accepts submissions from within and across subject domains such as those represented within the broad thematic areas below: Mathematical and Physical Sciences; Environmental Sciences; Medical and Biological Sciences; Humanities, Arts and Social Sciences. Originating from these broad thematic areas, the journal also welcomes submissions of software that works in cross cutting thematic areas, such as citizen science, cybersecurity, digital economy, energy, global resource stewardship, health and wellbeing, etcetera. SoftwareX specifically aims to accept submissions representing domain-independent software that may impact more than one research domain.
