Description
A Tier-3g Facility within the computing resources of Istanbul Aydin
University has been planned and installed in collaboration with TR-ULAKBIM national
Tier-2 center. The facility is intended to provide an upgraded data analysis
infrastructure to CERN researchers considering the recent nation-wide projects of ATLAS and
CMS experiments. The fundamental design of Tier-3g has been detailed in this work with an emphasis
on technical implementations of the following parts: Virtualization
of all nodes, VOMS usage for reaching fast experimental data in the
WLCG network, batch cluster / multicore computing with HTCONDOR and
PROOF systems, usage of grid proxies to access code libraries in AFS
and CVMFS, dynamic disc space allocation and remote system mounting
of EOS. We also present the performance test results that was
obtained during a typical simulation of official analysis tools.
