A test of the interoperability of grid middleware for the Korean High Energy Physics Data Grid system

In this paper, the current architecture of the High Energy Physics (HEP) data grid system in Korea is described. An overview is given for the current and planned uses of grid technology of the Korean Grid Project and especially for computing on HEP. The HEP data grid in Korea has been developed for CDF (Collider Detector at Fermilab), CMS (Compact Muon Solenoid), Belle, and AMS (Alpha Magnetic Spectrometer) experiments. We have first suggested and designed the DCAF(Decentralized CDF Analysis Farm) outside Fermilab for CDF. We have also first constructed interoperability between DCAF and other farms. Therefore, this paper addresses the grid farms for the experiments and the interoperability issues between the farms. The main grid farm locates at the Center for High Energy Physics (CHEP) at Kyungpook National University (KNU) in Korea.
