S3 Planning

KR went through a list of S3 planning issues / ideas discussed at the June 20 telecon to give status updates or to query participants for updates -->  See list with annotations from this meeting

DMT Software Status Review:

 
• Status of DMT infrastructure

 
• John Zweizig: Version updates, etc.

John reported on a new Monte Carlo feature in the DMT that allows merging of real data files with simulated data, where the simulated data is created from a number of newly supported waveforms (sinusoids, sine-Gaussians, white noise, etc.). The simulated, merged data can also be subjected to "filtration" which includes fir & iir filters, time delays and limiters to mimic parts of the DAQ system. This new facility should be useful in testing DMT monitors. John will give a more detailed report at the Hannover meeting.
A new DMT release that includes the new Monte Carlo code is imminent at the observatory sites. There remains an update delay between the online DMT machines and the GC machines (fortress at LHO, decatur at LLO) which may impede certain DMT developers using the latest DMT infrastructure tools.
 
• Status of DMT monitors

 
• Dave Chin / Tim Bodiya: LockLoss and ServoMon/SpecMon

KR reported that SpecMon (new gui-driven version of ServoMon) will not be ready for testing at the end of August, as planned. It looks touch and go for being ready for production use in S3.
 
• Masahiro Ito: glitchMon

Aside from new channel additions (discussed above under S3 planning), work continues on incorporating Shourov Chatterji's linear predictive filtering code into the glitchmon front end. The filtering will be available as an option.
 
• Sergey Klimenko: LineMonitor and WaveMon

No update.
 
• Szabi Marka: IRIG-B, TimeMon, and ShapeMon

No update.
 
• Tim Olson: SpectrumArchiver

Following a suggestion from Daniel, Tim has put together a list of all fast (16 kHz) channels and all PEM channels for atuomated spectrum archiving. At LLO alone, this amounts to about 1100 channels, 2.7 GB/day, and 980 GB/year, which seems like a lot. He would like guidance on which of those channels should really be stored. John noted that about a quarter of all 16 kHz channels in the data stream are excitations that need not be stored unless non-zero. KR suggested that Tim post his LLO and LHO channel  lists and implied data rates, then send e-mail to the detchar and commissioning mailing lists requesting input. KR reminded everyone that storing a huge number of seemingly obscure channels is not necessarily crazy, since these are meant to provide a spectral history for not only data runs, but also for commissioners working between runs.
 
• Steve Penn / Vijay Chickarmane: BicoMon

Steve continues work on a new GUI interface for the foreground version of BicoMon. He has had some technical troubles with getting the framecpp library working on his local Hobart machine.
 
• Brian Stubbs: SuspensionMon

See S3 planning discussion above.
 
• Patrick Sutton / Mike Ashley: SenseMonitor / CalMonitor and RayleighMonitor

See S3 planning discussion above.
 
• John Zweizig: BitTest,  DataQual, HistCompr, PSLMon, and SegGener

No recent changes.

A.O.B.

• KR continues revising the agenda for the Hannover meeting's detchar sessions
