2018 CICC architecture and facilities
In 2020, the following works were performed to change the configuration of Tir2 (JINR-LCG2):
1) Changed batch server to Slurm type. Works and is used by CE.
2) Changed Computing Element (CE) for WLCG type – ARC6 (internal slurm queue). (CREAM-CE is no longer supported by the central task launcher).
3) the farm is transferred to Scientific Linux release 7 system.
4) Added new tape robot (TS4500).
5) PhEDEx is replaced by RUCIO.
6) New servers are connected in EOS.
7) User interface lxui [01-04] .jinr.ru as a gateway for external connections
8) Increased disk space of the interactive cluster /scrc (2.2TB)
