2. Mission The Computing Centre (CC) is an IT supporting department to provide quality computing and network services to the Institute. – Deploy, operate and manage the high performance scientific computing and network infrastructure – Provide Internet and other relevant services to the users. – Research and applications on cyber securities – Build and develop scientific database systems Some relevant R&Ds are carried out to foster the above tasks October 24 ， 2013 2

3. History IHEP CC has been the pioneer of IT in China. – 1986 IHEP established the first Internet connection to CERN using point-to-point link largely promoted the collaborations on ALEPH and L3 experiments between China and CERN. – 1988, an x.25 link was established between IHEP and CERN – 1993, the network was upgraded to a 64 Kbps satellite link between IHEP and SLAC in the US. This was the first permanent Internet link from China to the rest of the world. – 1994 the first China’s web site was set up at IHEP. This web site made great contributions to the development and dissemination of Internet in China. – In last ten years, new technologies like Grid/Cloud computing have been developed and implemented.

14. Dissemination With its newly developed technologies and expertise, CC helped organizations to build or improve their IT systems – Computing and storage system, data management system, network monitoring and management system, etc. – Beneficiaries include Institutes, Universities, etc. AMSS, IBCAS, ITPCAS, RCEES, SEMI, CASEBA, INEST of CAS; Shandong Univ., Shanghai Jiaotong Univ., etc. Industries October 24 ， 2013 14

15. Dissemination Launched first Chinese volunteer computing project, CAS@home. – Harness public computing resources for scientific computing – More than 100k public CPU cores registered. – Applications of protein structure prediction, nanotechnology, cancer genomics, HEP, etc. are supported. Built Open Scientific Big Data platform – Provide integrated services including data fetching, storage, computing, … – Support Chinese First bigdata contest launched by CCF (Chinese Computer Federation). – Thousands of public users October 24 ， 2013 15

16. Challenges As IHEP is involved in more new large scale HEP related projects, IT infrastructure needs to be ramped up very quickly. This leads to new challenges to building, operating and maintaining the system. Heavy burden of IT operations makes high level staff difficult to focus on visioning R&D works. Stable support to fabric upgrade and renew is far from enough. October 24 ， 2013 16

17. Solutions and Prospects Adopt new technologies and improve the efficiency and quality of IT operations Continue the R&D on the scientific computing and network, to fulfill the computing requirements of new HEP projects. – Cloud computing, big data, IPv6, SDN, security, … – International collaborations. Seek close collaborations with international and domestic labs and industries. More efforts will be made to seek solid and stable financial support from funding agencies October 24 ， 2013 17

18. Summary IHEP CC has been the active IT player in the HEP community, as well as in other science disciplines. As a well-experienced team IHEP CC provides quality computing and network services to the Institute. More challenges we have to take up. But we will continue to move forward. October 24 ， 2013 18
