Description
This paper describes the deployment and configuration of the
production system for ATLAS Data Challenge 2 starting in May 2004,
at Brookhaven National Laboratory, which is the Tier1 center in
the United States for the International ATLAS experiment. We will
discuss the installation of Windmill (supervisor) and Capone (executor)
software packages on the submission host and the relevant security
issues. The Grid3+ infrastructure and information service are used
for the deployment of grid enabled ATLAS transformations on the Grid3+
computing elements. The Tier 1 hardware configuration includes 95
dual processor Linux compute nodes, 24 TB of NFS disk and an HPSS
mass storage system. VOMS server maintains both VO services for US
ATLAS and BNL local site policies. This paper describes the work of
optimizing the performance and efficiency of this configuration.
