Grid VPN between IHEP and USTC • Motivation • International bandwidth bottleneck of China universities • Academic users in universities have to use commercial service shared with millions of public users. • Grid won’t be function this way! • Solution • Virtual Private Network (VPN) channel between CSTNET (USTC) and CSTNET (IHEP). d 0 ustc gain 120 -600 k. Bps stable net connection. Gang Chen/CC/IHEP 2020/9/24 - 16

Other Activities • Partner of EUChina. GRID project • Aims to support the interoperability of the Grid infrastructures in Europe (EGEE) and China (CNGRID) for the benefit of e. Science applications • To foster the creation of a intercontinental e. Science community Training people § Supporting existing and new applications § • The official start is 1 st January 2006, 24 Months duration • Support ATLAS and CMS@LHC and the Cosmic Ray Experiment ARGO in Yangbajing • Attend WISDOM data challenge • scheduled from 01/10/2006 to 15/12/2006 Gang Chen/CC/IHEP 2020/9/24 - 18

Current Problems • Network performance is limited • Well Trained Manpower is not sufficient • More user tutorials is needed Gang Chen/CC/IHEP 2020/9/24 - 19

Beijing Site in the Future • Beijing site have been extended up to more computing power and storage capacity, will provide more powerful resource support. • Signed MOU for building two T 2 for CMS and Atlas respectively: 2 X Tier 2 CPU (k.
