Several computing nodes are installed in the counting house and will be used for the ODC. Where possible, we try and follow the conventions outlined on the wiki conventions outlined on the wiki Their role assignments are shown in the following diagram and describe in more detail below.

ODC2013 NodeAssignments.png


  • gluon44: Simulated EB (Event Builder) node
    • Raw data files stored on local disk
    • ET system
      • fed locally using file2et program
      • L3 nodes will attach remotely to read events
      • Monitoring server will attach remotely to read events


  • gluon45: Monitoring server node
    • Reads events from EB node and supplies them to all monitoring nodes
    • ET system
      • fed using locally run et2et program which pulls events from EB node
      • Monitoring nodes will attach remotely to read events


  • halldraid1: ER and RAID disk node
    • Reads events from local ET system and writes them to files on local RAID disk
    • ET system
      • fed remotely by L3 nodes
      • Locally run et2file program will serve as ER (Event Recorder)


  • gluon24: Server node
    • Webserver (primarily for serving Ganglia pages)


  • gluon20: Monitoring Nodes
    gluon21
    gluon22
    gluon23
    gluon40
    gluon41


  • gluon100: L3 nodes
    gluon101
    gluon102
    gluon103
    gluon42
    gluon43


In addition we will be using the 5 desktop computers in the counting room (gluon00-gluon04 ?)
