JINR LCG infrastructure
  • Current status of GRID infrastructure at JINR
  • The JINR Central Information and Computing Centre (CICC) is the element of Russian GRID Segment used for LHC computing and for the other applications. The CICC provides the necessary resources for different tasks, implied by many projects JINR researchers take part in: E391A (KEK), KLOD, COMPASS, D0, DIRAC, HARP, CMS, ALICE, ATLAS, HERAb, H1, NEMO, OPERA, HERMES, CBM, PANDA, etc. This year three cabinets (19”) were installed in the CICC with total amount of 60 dual-CPU dual-core computing nodes. Now 252 CPUs are used as working nodes. The CICC software includes a number of program packages which form GRID environment. A current version of the LCG software is gLite 3.0/3.1.
