Minutes of the LSUG Teleconference
Thursday, 12 September 2002  (10:00PST)
Attendance: 

        Duncan, Patrick, Xavier, Jolien, Kent, Stuart, Peter, Masha,
        Greg, Joe, John, Albert, 


Action:  

        1.  Changes to WrapperInterfaceDatatypes.h will be made by the
        Lab for LDAS 0.5.0.  The change will be made to LALWrapper CVS
        archive when 0.5.0 is released.  Jolien will push this change
        through the SCCB.

        2.  Stochastic group will develop new database tables as
        needed for that group.  This will be the first action for
        their group tomorrow.  


Agenda:

        LDAS status:  2.1 % at LHO,  2.6% at LLO,  1.1 at MIT.  Two
        cases - missing frames and DSO's seg-faulting were about
        equal.   Other causes were in 10^-3--10^-4 range mostly in
        user commands,  database issues at LHO,  power outage at LLO.  

        DSO failure rates:  tfclusters and slope were the ones causing
        the seg-faults.   This is far too high.   We need to get it
        under control.  

        LDAS code freeze will be roughly one week from today.  


        Proposed changes to WrapperInterfaceDatatypes:  request came up
        several months ago,  people wanted to send data to DSO's which
        are not time/freq or other series that exist.   Adding one new
        structure and modifying the structure.   Ed thinks he do it in
        a few hours when Masha is ready for it.   Unanimous to go
        ahead with change.   

        All sites have 0.4.0 except PSU.    Change will go in
        LALWrapper after 0.5.0 release and Jolien will push the change
        around SCCB loop just to say we did.  


        John Whelan:  Stochastic analysis has been putting some output
        into the search summary table.  But this means that there are
        some problems because everything goes into the same table.
        Idea is that there should be a table called multi-stochastic
        has been kicking around for a year.  Usually comes up when
        it's not a good time to make the change to LDAS.   Peter says
        that change can be made on dev system in a day or two.  The
        addition of the table has to happen in conjunction with a
        release.  This is a good time to do it.   Now the question is:
        what is the database?    After much discussion,  one or more
        database tables may be what they need.   Which ones they want
        will depend on what the search codes produce.   Action:  the
        stochastic group will need to come up with something
        reasonable.   Can add columns to a table as long as they are
        not unique ID's and things like that.   Are they close to
        using the new table design.    They need to get it in there
        before they are ready.   


        DSO's are not being used correctly:  there is a second type of
        analysis that is being done that is different to the basic
        algorithm.   


        Calibration:  we talked about it.
