The Nordic Grid facility (NorduGrid [1]) came into
operation during summer 2002 when the Scandinavian
ATLAS HEP group started to use the Grid for the
ATLAS Data Challenges (DC) and was thus the first Grid
ever contributing to an ATLAS production. Since then,
the Grid facility has been in continuous 24/7 operation.
NorduGrid is being used by a growing set of active
users from various scientific areas including physics,
chemistry, biology and informatics. It has given major
contributions to the ATLAS Data Challenge 1 [2] and the
ongoing Data Challenge 2.
· The increasing number of resources has made
NorduGrid one of the largest production Grids in
the world, continuously running on more than 30
sites more than 3000 CPUs.
· The resources range from small test clusters at
academic institutions to large farms at several
supercomputer centers and the NorduGrid
software runs on clusters with very different Linux
distributions.
This presentation gives a short overview of the design
and implementation of the NorduGrid middleware,
logging and monitoring facilities. It will be followed by a
description of a typical job on NorduGrid and the
information about its parameters which are monitored online
and persistified in the logging service.
