First computing shift tutorial at ROC@Beijing

  • 9 people from IHEP, 3 people from PKU, 3 people from CERN (Peter Keruzer, Dong Liang, etc) joined the tutorial.
    9 people from IHEP including: Ming Yang, Xiangwei Meng , Xianyou Wang, Jian Wang,  Song Liang, Hong xiao, Zhenxia zhang, ZhiChen Tan, Xiaomei Zhang  
    3 people from PKU including Prof Sijin Qian, Shuang Guo and Fangzhou Zhang
       

  • Peter Kreuzer presented a complete and very nice tutorial for us:
    (1)   Brief Introduction of CMS computing
    (2)   Overview of CMS computing shifts: history, status, policy, general procedure, useful links
    (3)   Describe how and what to do in a shift as a CSP in detail, including how to sign up for shifts; how to do the check and monitor for six parts of cms computing system; how to raise alarm including writing Elog, issuing savannah tickets; how to contact the related experts and persons. 
    (4)   Describe how to use \x{9225}\x{6e1f}hift homework\x{9225}\x{fffd} twiki during trial shift this week
      

Second computing shift tutorial at ROC@Beijing

  • 11 people from IHEP , 10 people from PKU, 4 people from CERN (Peter Keruzer, Dong Liang, etc) joined the tutorial.

11 people from IHEP including: Ming Yang, Xiangwei Meng , Xianyou Wang, Jian Wang,  Song Liang, Hong xiao, Zhenxia zhang, ZhiChen Tan, Ming Xu, JunQuan Tao, Xiaomei Zhang  
10 people from PKU including:  prof Sijin QIAN and Siguang Wang, students Zhen HU, Wenbo Li, Yifei Guo, Linlin ZHANG, Wei Zou,  Fangzhou ZHANG, Dong Wang, Shuang Guo
   

  • 2. Peter Kreuzer gave an overview of CSP for us:
    • CMSROC@Beijing performance, issues since August
    • plans to integrate more shifters from CMSROC@Beijing
    • CMS Computing Operations plans until LHC startup
    • Issues and suggestions to the CSPs

  • 4. Five current shifters( Ming Yang, Xianyou Wang, Jian Wang, Song Liang, Hong Xiao) go through five monitoring parts of CSP
    Because of limited time(the meeting continued until 18:30), we can not go into details, 
    but we did get some valuable feedback from the current CSP and the new shifters,  and Liang Dong help answer the questions.
    In order to get more feedback from shifters, I open a place for shifters in the IHEP twiki to give your questions and suggestions freely
    and also I summary today's feedback here:
    http://twiki.ihep.ac.cn/twiki/view/CMS/Feedback
      

  • 5. Discussions and Decisions:
    • Future shift arrangement:
      [1]9 IHEP people and 7 PKU people are available for shifts in the future.
      [2]10 new shifters will take real shifts since December, and they will take passive shifts after Oct 8.
      [3]Uniform local arrangement of shifts by xiaomei zhang, and pubish next month's shift table in twiki  a week before the end of this month. 
      [4]We wonder if the weekend shift have more weights than the normal shift?
             
    • No shifts in National Day holiday
    • All the shifters agree to do the shifts in the CMSROC@Beijing room in time in the future.

Third computing shift tutorial at ROC@Beijing before LHC startup

  • people from IHEP, from PKU, from CERN (Peter Keruzer) joined the tutorial.
       people from IHEP including: Guoming Chen, Jianguo Bian, Ming Yang, Xiangwei Meng , Xianyou Wang, Jian Wang,  Song Liang, Hong xiao, Zhenxia zhang, ZhiChen Tan, Xiaomei Zhang
       

  • Peter Kreuzer gave us a report before LHC startup:
    (1)   CSP will play a key role after LHC startup, and shifters should be clear about your responsibility.
    (2)   Emphasize the critical service and sites CSP need to pay attention to
    (3)   Review the tasks of CSP during their shifts 
    (4)   Declare an important news for CMSROC@Beijing: CMSROC@Beijing is in direct connect with CMS P5, CC@CERN, FNAL ROC, DESY ROC, which let the Beijing CSP shift with the world, and also require the Beijing shift should always run from the shift room
    (5)    Strengthen what CSP should do and what CSP should not do during shifts.  
      

  • Some discussions:
    (1)   How to manage international call for critical or emergency moments?
            We will prepare a public skype account for such emergency call
    (2)   It is too early for Beijing shifters to be on the shift starting from 7:00AM in the morning specially in the cold winter for the PKU people
           We strongly suggested to postpone shift time zone one hours or two hours. something like:
         * 02pm~10am CERN time( 09am~17pm Beijing time)
         * 10am~18pm CERN time (European Zone)
         * 18pm~2am CERN time(American Zone)
