2020: 1) Changed batch server to Slurm type. Works and is used by CE. 2) Changed Computing Element (CE) for WLCG type - ARC6. (CREAM-CE is no longer supported by the central service launching tasks). 3) the farm is transferred to Scientific Linux release 7 4) Added new tape robot (IBM TS4500). 5) PhEDEx replaced by RUCIO. 6) New EOS servers was hooked up. 7) User interface lxui [01-04] .jinr.ru (gateway for external connections) 8) Increased disk space of the interactive cluster /scrc (2.2TB)
