  1. IHEP Computing Center Site Report Shi, Jingyan (shi.jingyan@ihep.ac.cn) Computing Center, IHEP

  2. Beijing Spectrum ARGO-YBJ Detector IHEP Brief introduction • The largest(~1000 stuffs) fundamental research center in China with research fields including: • Particle Physics Experiments • Cosmic Ray/Astrophysics experiments • Theoretical Physics • … • Scientific projects: • BESIII experiment running on BEPC • ARGO-YBJ experiment • Daya Bay reactor neutrino experiment   • ATLAS, CMS experiment on LHC • AMS, HMXT … Shi,Jingyan/CC/IHEP 2014/9/15 - 2

  3. CC-IHEP at a Glance • The Computing Center was created in 1980’s • Provided computing service to BES, the experiment on BEPC • Rebuilt in 2005 for the new projects: • BES-III on BEPC-II • Tier-2 for ATLAS, CMS • Cosmic ray experiments • 35 FTEs, half of them for computing facility Shi,Jingyan 2014/9/15 - 3

  4. Outside data farms: LHC, YBJ,DAYABAY WAN Login, monitoring, scheduling,AFS,backup… More than 8000 CPU cores 10Gbit Ethernet Local data farm 3+ PB disk storage ( Lustre ,dpm, dCache) 5PB tape storage Shi,Jingyan 2014/9/15 - 4

  5. IHEP Campus Network • Network upgrade finished last month • IPv4/IPv6 enabled for all users • Campus wireless network covered Shi,Jingyan– Kan, Bowen/CC/IHEP 2014/9/15 - 5

  6. Network connection USA EUR. Others ASGC GLORIAD 10G 2.5G TEIN3 Hong Kong Beijing Tsinghua 2.5G EDU.CN 2.5G 1G Beijing CSTNet 155M IPv4 10G IPv6 YBJ Daya Bay IHEP Shen Zhen 155M Shi,Jingyan/CC/IHEP 2014/9/15 - 6

  7. Computing Resources • Local Cluster & Grid Site • Cpu: • Work node: More than 8000 cpu/cores • Storage: • 3+PB storage • Lustre for local cluster • dCache for CMS • DPM for ATLAS • 5PB Tape storage • Scheduler • Cluster: PBS + Maui Shi,Jingyan 2014/9/15 - 7

  8. File system - Lustre • 4 MDSs, 39 OSSs, 376 OSTs, 800 client nodes, 135 million files • Lustre Version: 1.8.5 ( upgraded in July) and 1.8.6 (with a new mount point) • Capacity: 2.8PB • IHEP is considering binding Lustre with CASTOR 1.7 using the HSM function provided by Lustre 2.x, however, it seems that the HSM feature has not totally landed in stable version of Lustre

  9. Disk Error • More than 3000 pieces of disks are used for the storage and 2/3 have expired guarantee period • 1TB disks: 1972 pieces • 2TB disks: 752 pieces • 3TB disks: 432 pieces • Disk hard error happened once 3-4 days in average • Spare parts are limited, especially for 1TB disks • Considering a way to upgrade those disks smoothly Shi,Jingyan 2014/9/15 - 9

  10. IHEP - CA • Number of issued certificates • CooperationOrganizations Last update: Apr20 2012 UTC+8 Shi,Jingyan– Kan, Bowen/CC/IHEP 2014/9/15 - 10

  11. CA need to be upgraded • According to the GFD.125, emailAddress (or Email) now MUST NOT be used in subject or issuer DNs. • IHEP will follow the steps below to remove the emailAddress. 1. Modify the CP/CPS to comply with GFD.125 2. Generate a new key pair (new root CA cert) . Register it to the IGTF repository so that the new root CA cert and related files will be included in the IGTF CA distribution 3. Inform the relying parties that the subject DN of CA certs and EE certs would be changed. New root CA will issue new EE certs 4. Revoke the old CA certificate until all EE certificates issued by the old CA key will be expired Shi,Jingyan 2014/9/15 - 11

  14. Reliability and Availability

  15. Site Operation • Some new computing resources will be added • 16 old WN will be replaced with new blade before JUL. 2012 • HEPSPEC 2006 will rise up from 8000 to 9600 • EGEE to EGI migration • Testing new system • Grid middleware upgrade • Keep eyes on other sites’ migration.

  16. Question & Thank You
