Description

The Jiangmen Underground Neutrino Observatory (JUNO) is an underground 20 kton liquid scintillator detector being constructed in southern China. The JUNO physics program aims to explore neutrino properties, particularly through electron anti-neutrinos emitted from two nuclear power complexes at a baseline of approximately 53 km. Targeting an unprecedented relative energy resolution of 3% at 1 MeV, JUNO will study neutrino oscillation phenomena and determine neutrino mass ordering with a statistical significance of about 3 sigma within six years. Currently, JUNO is in the commissioning phase.

During physics data collection, the expected data rate after the global trigger is approximately 40 GB/s, which will be reduced to ~60 MB/s using online event classification. This means an estimated dataflow of about 3PB/year, considering also some auxiliary files.

These challenges are addressed by a large collaboration spanning three continents. A key factor in JUNO's success will be the implementation of a distributed computing infrastructure (DCI) to meet its predicted computing needs.

The development of this computing infrastructure is a joint effort by four data centers already active in the Worldwide LHC Computing Grid (WLCG). Produced data will be stored in these data centers, and data analysis activities will be carried out cooperatively through a coordinated joint effort.

This contribution reports on the design, implementation and deployment of the JUNO DCI, describing its main characteristics and requirements.
