【 摘 要 】

High Energy Physics is one of the research areas where the accomplishment of scientific results is inconceivable without a complex computing infrastructure. This includes also the experiments at the Large Hadron Collider (LHC) at CERN where the production and analysis environment is provided by the Worldwide LHC Computing Grid (WLCG). A very important part of this system is represented by sites classified as Tier-2s: they deliver a half of the computing and disk storage capacity of the whole WLCG. In this contribution we present an overview of the Tier-2 site praguelcg2 in Prague, the largest site in the Czech Republic providing computing and storage services for particle physics experiments. A brief history flashback, current status report and future perspectives of the site will be presented.
