Grid computing enables the massive computer resource sharing, so that many applications (e.g. experimental high energy physics (HEP) and biology researches, etc.) can be greatly benefited from this new technology to proceed to the level which was unthinkable or unreachable before. Peking University is one of 10 partners in the EUChinaGRID project funded by European Commission. In this paper, the BEIJING-PKU site (based on the middleware gLite of European grid project EGEE) in the EUChinaGRID infrastructure is described. Some result of grid application in Peking University and our future plans (on HEP and biology applications as well as on the grid technology development itself) are outlined.
