The JINR neutrino program.
JUNO — (Jiangmen Underground Neutrino Observatory, China) is a planned precision experiment with a new generation of reactor antineutrinos designed to determine the mass hierarchy of neutrinos.
The JINR CICC functions as a Tier-1 site in the JUNO collaboration (alongside IHEP, CNAF, etc.)The CICC provides all computing and storage resources .
Storage systems used:
dCache is used to store processed data (ROOT format) .
EOS — temporary used till dCache gains enough space
EOS + CTA is used only for archival — no direct user access to tape.
Access protocols:
xrootd on stable, high-throughput internal networks for tasks (fast, low latency).
HTTP / WebDAV on wide-area / global networks — more robust over less stable links.
Data lifecycle (for JINR):
Raw data arrive in IHEP and are distributed to Tier-1s (including JINR).
Processed data reside on dCache at JINR for ~2 years.
After that, data are migrated to EOS + CTA (tape archive).
Tape archives are strictly for long-term storage — never used by users or jobs directly.
