The Large Hadron Collider (LHC) of CERN which is the world's largest particle collider began to operate in 2010. The WLCG (Worldwide LHC Computing Grid) is a worldwide, distributed computing network of high standard, which has been established specifically to store, process, and evaluate large amounts of data originated from the detectors of the LHC. The center (T0) of this hierarchical computer network is in CERN, 11 international (T1) institutions are attached to it. T1 institutions are connected to more than 150 (T2) regional centers throughout the world. Research groups may access the WLCG through their own local (T3) centers connected to T2 regional centers.
The LHC Grid (T3) center in Debrecen has been established in 2011 by means of a research development infrastructural innovation support of the National Office for Research and Technology (NKTH), supervised by the Institute of Nuclear Research of the Hungarian Academy of Sciences (MTA ATOMKI). A modern, secure environment has been built under this project for the grid center operating with 120 processing units, 288 GB memory, and 120 TB storage in the beginning, starting in early 2012. The infrastructure enables further extension of the grid center. We are planning to aquire additional computing capacity in the future by means of various research funds.
The primary function of the grid center in Debrecen is to support the CMS workgroup, which requires GLite middleware environment. It was a great challenge to install GLite in this special hardver environment, this presentation discusses the accomplishment of this task.
