DESCRIPTION:Speakers: SMIRNOVA\, O. (Lund University\, Sweden)\nThe Nordic
  Grid facility (NorduGrid) came into production operation during\nthe summ
 er of 2002 when the Scandinavian Atlas HEP group started to use\nthe Grid 
 for the Atlas Data Challenges and was thus the first Grid ever\ncontributi
 ng to an Atlas production. Since then\, the Grid facility has\nbeen in con
 tinuous 24/7 operation offering an increasing number of\nresources to a gr
 owing set of active users coming from various scientific\nareas including 
 chemistry\, biology\, informatics. As of today the Grid has\ngrown into on
 e of the largest production Grids of the world continuously\nrunning Grid 
 jobs on the more than 30 Grid-connected sites which offer\nover 2000 CPUs.
 \n\nThis article will start with a short overview of the design and\nimple
 mentation of the Advanced Resource Connector (ARC)\, the NorduGrid\nmiddle
 ware\, which delivers reliable Grid services to the NorduGrid\nproduction 
 facility. This will be followed by a presentation of the\nlogging facility
  of NorduGrid\, describing the logging service and the\ncollected informat
 ion. The main part of the talk will focus on the\nanalysis of the collecte
 d logging information: usage statistics\, usage\npatterns (what is a typic
 al grid job on the NorduGrid looks like?). Use\ncases from different appli
 cation domains will also be discussed.\n\nReferences:\n-NorduGrid live: ww
