Description
The Jiangmen Underground Neutrino Observatory (JUNO) is a large-scale and multi-purpose neutrino experiment located 700 meters underground in southern China. The project began its design phase in 2013, has completed detector construction and started data taking in 2025. To provide a fundamental software framework supporting detector design, algorithm development, and long-term data processing and analysis, the JUNO offline software (JUNOSW) has been under development since 2012. In parallel, a distributed computing infrastructure (DCI) has been established to support large-scale data processing and analysis tasks. This poster presents an overview of JUNOSW and the DCI system. Built upon the Software for Non-Collider Physics Experiment (SNiPER) , JUNOSW integrates a comprehensive suite of applications, including simulation, calibration, reconstruction and analysis. These applications are supported by several core components: a ROOT-based Event Data Model (EDM), a unified Geometry Management System and a centralized Offline Database, all developed using modern software technologies and design principles. The DCI provides robust computing support for JUNO’s data workflows. It supports the production of simulation samples and enables large scale batch processing of raw data, ensuring reliable and efficient data handling during detector operation. JUNOSW and the DCI have become essential components of the JUNO experiment and contribute significantly to the achievement of its first physical results.
