PHENIX DC meeting

Aug 12, 99

in er experimented with
In ER experimented with...
  • 4 DCM crates - usually controlled one at a time during data taking, experimented on a regular basis with 2 DCM crates
  • 2 GTM crates: controlled one or two
  • 1 GL1 crate
  • NT-based SEB/ATP
  • one arcnet server program: ~ dozen FEMs
  • one event pool/logger on phoncs0
  • data rates <= ~ 1 Mby/sec
  • many standalone/debugging programs
upgrades of existing software
Upgrades of existing software
  • Arcnet server:
      • it remembers what has been downloaded when and can determine whether a new download is needed without operator intervention
      • speed up the corba server part
      • work on core arcnet code
  • DCM control:
      • allow crate/partition wide operation [logical unit is partition module]
  • DD/Logger/Monitoring:
      • allow parallel logging based on trigger types
      • have more than one monitor process
      • monitoring on other hosts in real time
  • User interface to run control
  • Central control of >1 granule (partition server)
  • Look into HV speed improvements (low priority), finish and use of HV OODBMS
new hardware software
New Hardware/Software
  • Counting house network/RCF connection:
      • purposely left out for ER
        • email on phenix-online-l and phenix-dc-l on Mar 23, 99
        • formally adopted in April 99 core week
      • need to specify hardware first
  • More computing (PCs/Linux) in 1008
  • Adding support for databases
      • run log
      • arcnet server
      • storing configuration information
  • More online diagnostic tools of all of the online system (ONCS and non-ONCS)
  • LV remote control (replace Genie with EPICS control)
online monitoring
Online Monitoring
  • Interface between detector groups and online group
  • Common setup between offline and online (RCF/1008)
  • Consistent interface between offline/online (fileEventIterator / ddEventIterator)
  • Preparations:
      • One day online monitoring workshop Nov 98
      • Presentations in
        • a) computing meetings Jan (MLP), Feb(MLP), April (CW), May (MLP)
        • b) run meeting (July/MLP)
  • Code templates available on
      • common tool box
      • oMonitor classes
      • Manuals in place (ONCS homepage)
  • Importance of adopting this framework by all subsystems
  • PHENIX-wide monitoring czar (we have one candidate)
conclusions
Conclusions

The online system took data

The two sides of

developing/debugging online system/code

and helping detector people to using it
