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:
- 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 ?)
