  1. ONCS Year 1 configuration C.Witzig PHENIX DC meeting Aug 12, 99

  2. 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

  3. 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

  4. 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)

  5. 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)

  6. Conclusions The online system took data The two sides of developing/debugging online system/code and helping detector people to using it
