论文摘要
低频阵列是由遍布欧洲的观测站组成的低频无线电干涉仪，就有效面积和产生的数据速率而言，它是SKA的最大先驱。 2018年，意大利社区正式加入了Lofar项目，并部署了专门用于Lofar数据分析的分布式计算和存储基础架构。该基础架构基于在意大利不同位置分布的4个节点，并为管道执行，最终和中间结果的存储提供服务，以及用于使用软件和基础架构的支持。由于对低频阵列数据的分析需要一个非常复杂的计算过程，因此采用了基于容器的方法将软件环境分配给不同的计算资源。科学平台方法用于促进对计算资源的交互式访问。在本文中，我们描述了基础架构的架构和主要特征。
The LOw-Frequency ARray is a low-frequency radio interferometer composed by observational stations spread across Europe and it is the largest precursor of SKA in terms of effective area and generated data rates. In 2018, the Italian community officially joined LOFAR project, and it deployed a distributed computing and storage infrastructure dedicated to LOFAR data analysis. The infrastructure is based on 4 nodes distributed in different Italian locations and it offers services for pipelines execution, storage of final and intermediate results and support for the use of the software and infrastructure. As the analysis of the LOw-Frequency ARray data requires a very complex computational procedure, a container-based approach has been adopted to distribute software environments to the different computing resources. A science platform approach is used to facilitate interactive access to computational resources. In this paper, we describe the architecture and main features of the infrastructure.
