The service support system provides the following:

  • computing service,
  • storage services,
  • GRID systems, data transfer services ,
  • distributed computing control systems ,
  • information service (monitoring services, servers, storage, data transfer, information sites).
  • Computing Resources  ( CE):
    • Interactive cluster: lxpub [01-05] .jinr.ru
    • User interface lxui [01-04] .jinr.ru (gateway for external connections)
    • Computing farms:

    –general purpose farm,

    –farm for LHC experiments,

    –cluster for NICA, MPD, BM@N (lxmpd-ui.jinr.ru)
