BM@N (Baryonic Matter at Nuclotron) is the first experiment to be realized at the accelerator complex of NICA-Nuclotron at JINR (Dubna, Russia).
The aim of the experiment is to study interactions of relativistic heavy ion beams with energy up to 5.5 AGeV with fixed targets.
The research program of the experiment includes studies of strange mesons, multi-strange hyperons and light hyper-nuclei which are produced in nucleus-nucleus collisions close to the kinematic threshold.
Software.
The CVMFS system is used to deploy the software.

BMNROOT
The BmnRoot framework is developed for realistic event simulation, reconstruction of experimental or simulated data and following physics analysis of ion collisions with a fixed target at the BM@N facility:
has been actively developing since 2014

based on and FairRoot
BM@N uses the DIRAC loading and data management system.
Computing platforms for BM@N:
- GRID Tier1&2 lxui.jinr.ru; Tier1: 1500 cores (for NICA),
Tier2: 1000 cores (for NICA) - NICA Cluster ncx[101-106].jinr.ru (LHEP, b.216) ; 300 cores (per user)
- HybriLIT platform (SC «Govorun») hydra.jinr.ru; 192 cores
- SLURM: 0 ‒ 2500 cores (for NICA)
Storage system for BM@N
At CICC, the experiment BM@N uses a storage system EOS. There is currently 750.00TB (1500.00.00TB physical space ) allocated .
The BM@N set-up, the experimental program and first results of technical runs are presented here.
