The current era of Exascale computing brings ever growing demands on the amount of available computing performance, storage capacity and network throughput. This affects also the massive computing infrastructure for management of data produced by the experiments at the LHC, the Worldwide LHC Computing Grid (WLCG). The standard financing used for many years enabling the resource growth of 10-20 % is no more sufficient and to close the resource gap different methods are pursued. The sites involved in the WLCG are encouraged to find non-grid external resources to be used for WLCG tasks. Probably the most popular among them are High Performance Computing (HPC) Centers. In this contribution, we present an overview of one of the WLCG sites, the distributed Tier-2 center in Prague, Czech Republic.
