PR Users

• At SLAC the main PR production is done from babaropr account. bbrobjy is the one which takes care of DB and snapshot operations. bbrxtc is the one for import/export of xtc and root files to/from Padova. PR work can be done from any SLAC machine, although some special actions require log in one fo the farm machine. The import/export is operated on bbr-xfer02.slac.stanford.edu
• In Padova, PR work is done by bbrprmgr, while xtc operation are done by bbrxtc. The main machine for PR is bbr-user02.pd.infn.it and for xtc/DB it is bbr-import.pd.infn.it.

• There are 2 PC production and 1 test farms at SLAC:
  
  • PC1: oprserv01
  • PC2: oprserv02
  • PCTest: oprtest01 (for tests)
  Each PC farm has approximately 16 client nodes with double CPU. They are called tori00XX (valid on Sep.20, 2004). The names of machines could be found in /nfs/oprserv0x/u1/PCx/OprConfNodeListPCx.xml
• There are 7 ER production and 1 test farms at Padova. During Run5, 2-4 ER farms should be sufficient to keep up with IR2 input. The remaining N-1 ER farms are used mostly for reprocessing, or in time of severe delays. The last farm does the skimming for Run5 data.
  Each ER is connected with a PP farm, which does merging of root files and prepare QA root files and the giant postscript file.
  • ER1: opr1
  • ER2: opr2
  • ER3: opr3
  • ER4: opr4
  • ER5: opr5
  • ER6: opr6
  • ER7: opr7
  • ER0: opr0
    (for tests)
  Each ER farm has approximately 30-50 client nodes with double CPU. They are called bbr-farmXXX (or 10.100.2.XX where last XX correspond to the number in bbr-farm name ) (valid on Apr.20, 2005). The names of machines could be found in /nfs/oprx/Reprocessing/XXx/OprConfNodeListXXx.xml .

The directories for all the farms have the same structure:

• At SLAC:
  • /nfs/oprserv0x/u1/XX#/prod
  • /nfs/oprserv0x/u1/XX#/logfiles
  • /nfs/oprserv0x/u1/XX#/xtcfiles
  • /nfs/oprserv0x/u1/TAO
  where XX = PC or ER.
• In Padova it is:
  • /nfs/oprx/Reprocessing/XX#/prod
  • /nfs/oprx/Reprocessing/XX#/logfiles
  • /xtc on the OPR server
  • $TAO_NS_ROOT

The following packages are currently needed to run the control system:

• OprProcessingSys
• OprControlSys
• OprQaUtils
