ONCS Year 1 configuration

C.Witzig

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
