LIGO Weekly Site Telecon (Lindquist)
A site teleconference was held on Thursday, March 4, 2004.  The following were discussed:

• Apartment for Livingston Travelers: an action has been assigned (Action 123--E. Jasnow) to work with Livingston to study the feasibility and formulate a process for renting an apartment at Livingston to be used by travelers.  Mike Zucker provided a summary of information to date.  Ed Jasnow to see if we can negotiate competitive rates.
• Budget: Reports for the end of February were released March 2.
• A new schedule has been added to provide details on travel expenditures. Travel expenditures for the period are in excess of travel budget for the period by $18K. An analysis done by Dennis Coyne and Michael Zucker, of the Livingston commissioning travel indicates a significant amount of the Livingston travel expenditures to date were for S3 Sci Mon travel.
• CR040002 which added funds to the Hanford site budget, by reallocation of some funds from the Hanford Outreach budget and $39K from the Director’s budget, has been reflected on this report.
• Expenditures to date are approximately $1 million higher than the same period last year.  We are only running at about 74 percent of our FY 2004 budget (straight-lined).  However, this is misleading since we are significantly behind in the R&D accounts (and some major equipment charges should hit soon) and a significant amount is set aside in planning packages in the Director's Office account.  Other accounts are more or less on target.
• New Telephone Conference Call Carrier: It appears that we can get the same service that we get from AT&T with a company called Rain Dance at about 1/4 the cost.  We are going to try this carrier for our site teleconference meetings.
• LIGO Video: Tom Lucas (Lucas Productions) has been selected by the NSF to do a LIGO Video.  To visited MIT this week and will be at Livingston March 16 and 17.  We will try to fit in some discussions with people attending the LSC meetings.
• There will be no meeting next week due to travel for key participants of this teleconference.

LIGO Hanford Observatory (LHO) and Interferometer Operations (Raab)

Summary of Commissioning Activities at LIGO Hanford Observatory  (compiled by M. Landry)

Thermal compensation studies continued, occupying much of the time on the 4k
this week.  Initial studies with a state 4 full lock occured on Friday.
At this early stage, the assessment was that the TCS was doing a reasonable
job of correcting the phase front curvature error in the PRM.

Later studies incuded asymmetrical PRM heating (only ITMY), and here with ITMX.

TCS modelling has shown that 1cm offsets in the position of the central heating spot on
the test mass are tolerable.  Furthermore, the factor of ~3 more heating required (than
expected) to optimize the sideband power (noted last week) was shown to be not due
to this type of offset.

Other TC studies included an annulus mask test, another state 4 heating curve,
and another asymmetrical heating study.

Using the Spiricon frame grabber to estimate the position of IFO beam on the BS,
an alignment servo was formed, feeding back to MMT2.

Recall that dust falling through the beam on ISC tables produces glithes; a
HEPA filtering system was added to ISCT4 last Friday, intended for cleaning after
an entry onto the table.  Studies are underway to see if the filter is effective cleaning
agent.

Violin resonances (both ITMs and ETMs) appear to have RMS a factor of four
higher in S3 than in S2.  It is not easy to see how this could be the case, given
the differences in ITM and ETM drive configurations (radiation pressure?).

An effort was made to increase the power out of the H1 PSL, and confirm PMC loss
measurements (which followed on some measurements earlier in the week of PMC
losses and settings).

LIGO Livingston Observatory (LLO) and Interferometer Operations (Zucker)

---------------------------------------------------------------------
L1 commissioning (summary by MZ)
--------------------------------------------------------------------
This week was a mad rush to complete interferometer diagnostics
(mostly related to high power operation, thermal lensing, and
understanding the sideband buildup)
before we sealed the X end station off for the HEPI installation.
 

[Note: this is just a safety precaution, nothing is vented].
 

Unfortunately we were plagued by intermittent laser trouble; in the end,
this prevented us from getting much useful data for the week. The fault
presents itself as a thermal overload in the NPRO master oscillator,
although it is not clear if  recent cooling loop changes, a not-so-recent
increase in pump diode current, or a random unrelated
failure are contributing causes. We will investigate
further and determine if swapping in the spare MOPA is the best
way to go.
 

The good news: we sealed the X end station Thursday morning and
HEPI actuator installation is under way! (more below).
 

Education and Public Outreach (B. Wooley)
---------------------------------------------------------------------
LLO visited by 82 Seniors from Parkview Baptist.  Accompanied by their
physics instructor they enjoyed hands-science, a tour, and painting.
 
 

Safety (R. Riesen)
---------------------------------------------------------------------
The self-locking door handles on the 2 interior doors for the machine shop
have been replaced with non-locking handles.
 

Installed a UPS for the Laser Safety/ security system computer.
 

Completed the disposal of the GSA auction equipment that was at the
"in-town" warehouse.
 

I have "on-site" equipment ready for GSA removal.
 

Working on finishing the punch list for completion of safety items required
in the HPTF.
 

Found no safety concerns during my weekly site safety tour.
 

Continuing work on LLO's property audit paperwork for Ed Chargois.
 

Property tagged all existing HEPI equipment with the new "LLO Seismic"
stickers.
 

Updated and revised the Laser Safety/ Security log-in and operation
procedures.
 

Attempting to streamline the shipping and receiving procedures.
 

I have spent most of today overseeing safety procedures during the
installation of the HEPI system at the X-end station.
 

Scheduled CPR training for LLO personnel for the 20th and 21st of April
'04.  15 people have signed up so far.
 
 

HEPI fabrication and installation (J. Giaime, R. Abbott & MZ)
---------------------------------------------------------------------
After a status review Wednesday afternoon gave the green light, all
the X end alignment data were baselined and verified by the installation crew.
The X end gate valve was shut first thing Thursday. By 3 PM the entire
FAS/CAS package was gone from the first pier, and the template was set
for drilling the new holes in the pier top.  The new precision lift jig and
procedure worked as advertised. Film at 11.
 

In other news, after persistent bad luck (including
galvanically incompatible pressure sensors and a
"surprise" connector pinout change by the valve
vendor) the valve calibration stand
is finally in business. Katrina and Tom are busily calibrating the
first 8 valves needed for the X end (just in the nick of time).
 

Piping contractors continue to beat the schedule; Ken Mailand is
working hard to keep ahead of them with connection details
and fittings.
 
 

L1 commissioning (Frolov)
---------------------------------------------------------------------
I worked on testing the upgraded daq system. I diagnosed a
problem with the summing of the signals from the lsc as port photodiodes.
This problem was likely the reason for 10x higher than nominal
interferometer noise in the low noise state.
 

With Andri's help I installed and successfully ran Rana's ifo noise model
on my computer for the analysis of the ifo characterization data that
were collected after S3 run.
 
 

L1 commissioning (Gretarsson)
---------------------------------------------------------------------
Began working to make Rana's noise model more
accessible and easier to modify.  Once the initial stage is done, I will
post it on a website with instructions.
 
 

LDAS (I. Yakushin)
---------------------------------------------------------------------
LDAS admin:
1) The power panel's unfortunate property to physically disconnect power
to LDAS in response to short outages has been fixed by Rusyl and Excel:
it is now powered through LDAS UPS.
2) Requested IP addresses for grid computers.
 

Data analysis:
1) Continue running simulations on the whole S2.
2) Preparing presentations for LSC meeting.
3) Trying to use Shourov's linear prediction filters with waveburst.
4) Regenerated all sky black hole merger MDC frames after Patrick Sutton
discovered that they were actually half sky.
5) On Erik's request working on generating MDC frames with events
injected not only at zero time lag but at time lags that are multiples of 5 s.
 
 

General Computing (S. Roddy)
---------------------------------------------------------------------
 

General Computing (Shannon Roddy):
 

* Current bandwidth usage can be seen at
http://teche.ligo-la.caltech.edu/mrtg/LLO-Router/130.39.245.1_1.html
 

* Archived bandwidth usage can be seen at
http://teche.ligo-la.caltech.edu/mrtg/archive/ under the dated folder
for the week of interest.
 

* Finished moving all of the home directories to the new file server.  I
began moving them manually and realized it was going to take too long,
so I wrote a script to move the directories and update the NIS+ tables.
The script took 2 1/2 days to complete so I would have been there
forever moving the directories by hand.  All of the home directories are
now on the  RAID server.  Still have a few things to finish up, but for
the most part this is complete.
 

* Set up two laptops for Bonnie and Katrina to use for two tours this
week.
 

* Set up a replica NIS+ server to get ready to move more stuff off of
our old file server.  Had some issues in the middle of this, since the
UPS that baronne is plugged into had some problems during the
replication.  It caused NIS+ to crash, then the machine was not stable
and I had to reboot it.  Commands like ps would hang and never finish.
Luckily, the NIS+ tables were not corrupted.  The last time this
happened it took us over 12 hours to get everything back.  Once I got
everything stable and running again with the replica server running, I
decided to leave things alone for a while.
 

* Promoted the replica server to be the master server, removed baronne
as a server, and then created a new replica server for redundancy.  The
old NIS+ server is now a client.  The mail server (abundance) is now the
NIS+ server and touro is the replica.
 

* installed a tape drive on abundance to back up the mail spools and the
system.  Set up a script to run ufsdump nightly to the tape drive.
Later this will be set up in a different fashion, but this will give us
backups for now.
 

* still working on compiling more apps and moving the old ones to the
new file server.  Need to make sure that when I compile things that they
do not link to libraries in /usr/local since not all machines will have
the same packages.
 

* set up another ntop server so that I can monitor bandwidth usage.  I
will later be setting up snort and ACID on the inside of the firewall.
The new Cisco 3550 works great for this and is much more flexible than
the old PIX.  I can now span ports and use them for IDS purposes.  I
could not do this with the PIX.  However, the PIX will be useful when I
internalize the PCs.
 

* LSU contacted me about the old T1 router.  I think it is safe to say
that we will not need it anymore.  I have emailed them and told them
that I can return it since it is in their inventory.  I also contacted
Ric Simmons and asked him to turn off the T1 lines permanently now since
the GigE has been stable for the most part.
 

* Put in a request for 4 DNS changes for LDAS.  They are adding 4 new
gateways into the LDAS network.  In my opinion this violates the
"spirit" of the LIGO IT security plan, but there is probably not much
that can be done about it.  I count the number of gateways to internal
networks to be at least 12 now, though I am sure there are a couple I am
not thinking of off the top of my head.  This also puts the number of
operating systems at 4.  Many of the gateway machines do not have a
clear administrator responsible for the machines.  The only layer of
defense is the firewall and for some reasons this is not sufficient at
this point.  I am concerned that this will only get worse.
 

#MZ I'd like to be copied on reactions to this issue. I get
the distinct impression LDAS, GC, DMT and CDS admins need
improved coordination lab-wide, but would love to be reassured
if everything's truly peachy.
 

* Dell has provided a fix for the problems that I was experiencing on
the new Gigabit switch.  I have not implemented it yet, but it involves
a filter being put on our Foundry core switch.  Hopefully it will fix
the problem since I am only able to use 2/3 of the ports on the new
switch.  So far I am more pleased with Dell's support than I am with
their hardware.
 

#MZ hey, you can't have everything...
 
 

S2 Burst Analysis (K. Yoshiki Franzen)
---------------------------------------------------------------------
 

1) Finished my WaveMon veto study of the four interesting S2 burst events.
No L1, H1 or H2 WaveMon triggers have been found which can be used to veto
these events. Please find the complete result at
http://www.ligo-la.caltech.edu/~franzen/restricted/WBveto4.html
LSC Burst group password required.
 

2) Finished processing the remaining S2 playground H1 and H2 data with WaveMon.
We now have the complete set of WaveMon triggers from all three instruments. I
am now proceeding by calculating dead time fractions and WaveBurst veto
efficiencies.
 
 

CDS support (Ash Khan)
---------------------------------------------------------------------
1) Continuing the support and checking of the new DAQ system and upgrading
the procedures to reboot the controllers as we find new bugs.
 

2) Developing the software for the Laser power supply and the new Chiller
communication.

40 Meter Interferometer (Weinstein)

• Commissioning (Miyakawa, Vass, Ward):
• We closed up after a successful 4 week vent to install the two suspended recycling mirrors, PRM and SRM. We pumped down last Thursday with no problems, and now are at 9e-6 torr with the maglev turbopump alone.
• By Thursday evening, the mode cleaner was locked, and by Friday AM the FPMI was locked. Minimal re-alignment was necessary; the mirrors did not move much because of the pump down.
• All error signals are now much weaker, because only 7% of the light gets through the mis-aligned PRM; and the asymmetric port has an 8% transmitting mis-aligned SRM. As a result, the 60 Hz noise is now relatively much larger, and is a real problem for locking.
• Osamu hunted for the 60 Hz noise source. It's in the analog LSC crate, and it only goes away when all cables are unplugged and modules pulled out.
• The band-aid solution is to increase the gains on the RFPDs sensing the FPMI degrees of freedom at the POX, POY, and SP ports.
• Rob increased the gain on the POX RFPD, but couldn't do the POY; Ben is looking at it. Meanwhile, with this mod, the x-arm is locking robustly, with much-reduced relative 60 Hz noise.
• Osamu is now modifying the whitening filter gains and re-tuning the LSC servo filters, to optimize the control with these lower light levels.
• We will then want to recalibrate the FPMI and get a new calibrated noise curve.
• This past Tuesday, the HV cable(s) to the PZT steering mirror(s) at the end of the PSL table were bumped, and the mirror(s) moved (not sure which one, or both). Before understanding what happened, Osamu re-aligned the MC to the input PSL beam; as a result, the beam to the main IFO was different. Fortunately, we have QPDs monitoring the beam position / angle at the PSL and at the MC -> IFO hand-off. Osamu has now used these to re-establish the correct beam pointing at the PSL, and has brought the MC and and main IFO alignment back to where it was.
• Optical sensing (Kawazoe, Sakata):
• All 7 oplevs are working well after pumpdown.
• Shihori is checking out the installed beamline QPDs, and will install the last few (of 12). Then she'll calibrate them all.
• Fumiko did some more measurements to determine how well the oplevs sense the suspended optic pitch and yaw, above the noise. We remain unsure about how useful the oplev servos would be for us, whether we should bother to commission them, and over what frequency range they should act.
• Because of the large amount of light reflected from the PRM to the SP when it is aligned, we need to finally install and commission the electro-optic shutter (EOS) at the SP and AP ports. Fumiko and Shihori are working on this, and Bob is helping with the wiring.
• Bob is checking all the wiring for the remote control of the mechanical shutters for the PSL, SP, AP, MCR beamlines. We still need to complete the EPICS control software for these.
• All camera views are established for all 7 core optics and all 8 output beams, and all signals are going into the video switch. We still need a few more camera power supplies to make use of all cameras. Steve has them on order.
• All chamber illuminators are working and under EPICS control.
• Electronics (B. Abbott, Heefner, Taylor, Mageswaran)
• The monitoring readout of a couple (at least) of PSL channels (PMC transmitted DCPD and FSS transmitted DCPD) has been misbehaving badly for many months. This does not effect the servos. The cause is somewhere in the electronics rack, and Rob and Ben are searching for the problem.
• Jay reports that the PD needed for double demodulation has been tuned up and is ready for installation.The response has a notch at 166MHZ and peaks at 133 and 199MHz. The is ~30dB of suppression of the 166MHz. Better suppression will require a re-layout/redesign of the board.
• Mohana and Shihori are reviewing the long list of EPICS channels in the EPICS alarm handler, to establish good alarm limits on all channels.
• Steve and Bob spent some time cleaning up the PSL cable plant.
• We continue to think about the necessary mods to the LSC software to implement lock acquisition code.
• Digital suspension controllers (Sakata, B. Abbott, Heefner)
• On Wednesday, the DSC sensor ADCs (ICS 110b's) started to channel hop, and all the vertex suspension watchdogs tripped off. We rebooted the DSCs, and several suspensions came back, but not all. The DSC filtering computer c1suslinuxpc2, which services MC1, MC2, MC3 and SRM, wouldn't re-start; when manually restarted, it segfaulted (as if it was getting corrupted data from the sensors). Jay found a bad cable from the PRM side OSEM sensor; Ben fixed it; Alex restarted the DSC system. By the end of the day, all the DSC system is back up with all suspensions damping nicely.
• Shihori is diagonalizing the input matrices for the ETMX, PRM and SRM suspensions.
• Safety (all): We still need to document a satisfactory response to all of the action items from the safety inspection of 1/13/04. All the action items have been addressed, we just need to assemble documentation. Steve gave a safety lecture to new undergrad student Ben Olson who is looking at the STACIS system.
• South Annex Bake Ovens (Taylor):
• Bob continues to work with Larry and Dennis on rebuilding ovens C and F, aimed at achieving AdvLIGO cleanliness specs. He has placed orders for all parts for oven C.
• Bob is building hybrid OSEMs or Janeen, as well as spare OSEMs for the 40m suspensions.

LASTI (Ottaway)

LASTI WEEKLY (Allen, Mason, McInnes, Mittleman, Ottaway, Sarin, Ruet)
 

HEPI
We have finished reinstalling the actuators onto the BSC. After releasing
all of the stops we found that the springs were not acting as if they were
free (see LASTI ilog entry ilog for 2/27/04 entitled BSC - MOVING THE
PLATFORM WITH THE SPRINGS). It is likely that the springs are binding in
the housings near where they are secured. We are waiting on new equipment (to
replace what has been returned to Livingston) so that we can lift the
platform, release the tension in the springs and make adjustments. This
should not be a problem at the observatory since the design
has been changed. We have some improved isolation results for the HAM
chamber, which are
 

posted on the LASTI ilog, 2/27/04 - HAM Performance Results. The main
change in the controls was in the STS sensor correction filter. This
filter is still limited at low frequencies by the tilting of the floor, we hope
that there is less tilting at the observatory which will allow more low
frequency gain and improved performance.
 

Electronics design and fabrication
 

During the month of February, the following tasks were completed:
1] the fab, assembly, test and shipment of phase camera chassis #2 to Hanford.
2] the fab, assembly, test and shipment of position sensor tester #2 to
Livingston.
3] the transfer of my office essentials to the lab to eliminate inefficiences.
4] the compilation of critical parts shortages in the lab for restocking order.
 

HEPI VME Controls development
 

Developing and testing software for performing system identification on
the HEPI-HAM using the VME controls system. The motivation for doing this
is to test the infrastructure here at LASTI before we do system-ID at the
LLO HEPI installation starting about March 15. The software is DTT based,
i.e. uses DTT libraries for doing things like swept-sine measurements and
talking to EPICS. The notable additions are that saturations of
measured channels are monitored, so that drives to actuators are reduced
whenever saturations are detected. In addition, a number of channels are
tracked as 'safety channels' - a deviation from nominal of values of any
of the safety channels trips a safety trigger and shuts down the actuator
drive.
 

Mode Cleaner Fit Check Structure
 

Janeen Romie has sent us a structure that will allow us to check the fit
of MC Tripple suspensions to our Xend-Ham.
 

HEPI Installation
Ken spent two weeks at Livingston assisting in the preparation for HEPI
installation. Myron is now there for two weeks assisting in the
installation at the x-end.
A finite element model was created of a new BSC lift plate allowing the
stack to be lifted over the HEPI springs
 

Thermal Compensation Design
A meeting was held with the team which installed the thermal compensation
at Hanford. It was discovered that the mounts for the camera housing was
inadvertently installed upside down resulting in problems with the
installation.  A list of improvements was gathered for the camera housing
and laser enclosure for future systems
 

Data Analysis and Computing (Lazzarini)

Simulation and Modeling (Bhawal)
SimLIGO noise hunting:
-------------------------
(Matt) Mysterious noise source (in the model) which dominates around 100 Hz found
 to be the digitized REFL_I feeding into the MICH and PRC loops
 through off-diagonal elements.  Because of the CM loop closed on
 it, REFL_I only explores one or two bits and is thus a non-linear
 noise source.  Removal of the off-diagonal elements (which did
 nothing good) removed this noise source and put the SimLIGO
 seismic-only noise curve well below the SRD.
 

Effect of Thermal heating on WFS 3 and 4
-------------------------------------------
(Biplab) The contribution of common mode misalignments from Recycling
 mirror (RM), End mirrors (CEM) and Input mirrors (CIM) in the reflected
 port (non-resonant sideband frequency demodulated) Wave Front Sensors
 (No. 3 and 4) were calculated as a function of (i) Gouy phase and
 (ii) for different heated states.
 Results show that proper isolation of degrees of freedom at either
 WFS 3 or 4 needs a careful choice of Guoy phase in telescopes.
 With heating and proper choice of guoy phases, RM signal can increase
 by a factor of 3. CEM signal does not change at all by either common
 or differential heating simply because sidebands do not get affected
 by CEM mode of misalignment.
 

 Sent all results to Luca and Daniel. Also results can be looked at enote
 [elog-like but subject-based not date-based; Recently introduced
  by Bruce Sears]:  http://ldas-sw.ligo.caltech.edu/enote
 

Code for Dual-recycled Michelson
-----------------------------------
(Hiro) The fast but approximate field evolution calculation in a dual
 recycling Michelson cavity has been refined, and a code has been
 written in matlab for quick prototyping and debugging. The debugging
 is in the last stage. By the middle of next week, a preliminary
 document and completed matlab code will be ready for release.
 

Code development and maintenance
----------------------------------
(Hiro) Modeler code revision:
 Matt and Hiro worked to revise a template matrix class to implement
 the expression template technique. Now, most of the matrix and vector
 calculations can be coded as is, like
 

 E_front_reflected = FrontReflectionMatrix * E_front_in +
                     TransmissionMatrix * E_back_in
 

 without worrying about the C++ operator overloading overhead.
 

 The sparse matrix handling has been revised as well, which is
 important for the state space model simulation used for the many of
 the mechanical subsystems.
 

 Hayakawa of ICRR (Institute for Cosmic Ray Research, Japan) has 64bit machine in ICRR and has been serving as a
 very good guiena pig. For the release of e2e-1.9.0, he found a
 problem related to 64 bit architecture, and we could fix the problem
 very quickly with his concise debug information.
 

(Matt adds) Matrix Expression Templates:  new implementation allows for
 evaluation of any expression and can be specialized to evaluate
 specific expressions optimally. This seems to be ideal.
 

(Melody) Modeler:
 Working on some enhancements to the FUNC_X code.
 Worked on the FUNC_X technical document to describe the use of
 dynamic linking and shared libraries in E2E.
 

(Ed Maros) Worked on modifying installation according to Matt's
 experiences.
 

Alfi
-----------
(Bruce)
  - Redesign and implementation of connection building
    object in preparation for completing bundler rework.
 

(Melody) Working on executing the user's editor (specifically vi
  or emacs) as the default editor for the primitive settings.
 

LIGO Data Analysis System
 

Software Systems (Blackburn)
We've spent the last week and a half migrating to newer third party software
development tools. These have been tested on a tandem system and are being
moved onto the LDAS-DEV system today. This is primarily a maintenance related
activity with only minor bug fixes being addressed by the newer packages. The
list of upgraded packages is:
 

          * cURL - 7.11.0
          * coreutils - 5.2.0
          * binutils - 2.14
          * gcc - 3.3.3
          * lam - 7.0.4
          * xerces - 2.4.0
          * BWidget - 1.7.0
          * tth - 3.33
          * tkcvs - 7.2
 

We have begun the porting of LDAS and its dependencies over to the Solaris C/
C++ compiler. So far only the third party software in LDCG required to build
and run LDAS has been ported to the Solaris compilers. No issues have been
discovered at this phase of the port.
 

We have finally "cracked the nut" with regard to upgrading to the new DB2
database server. This is after over a year of frustration from lack of DB2
support on RH 9. IBM is now supporting DB2 under Redhat Enterprise and as
such has had to post several fixpacs and specialized install procedures. We
took these RH Enterprise procedures and applied them to RH 9 and with a bit
of juggling were able to find the combination of sequences to get the DB2
version 8.1 to run with LDAS 1.0.0. This database is expected to provide
new table support that potentially can greatly improved query times. It is
also expected to be about 20% faster all around. However, the real pay off
with this version is the ability to Federate the LDAS databases! This has
been on hold for over a year because the Java Administration tools didn't
work properly under RedHat 9 prior to this week's effort.
 

Several diskcacheAPI related bugs have been discovered in the LDAS 1.0.0
release when migrated to the sites. These are being worked on and should
be resolved in a week or two.
 

Other APIs that have had bug fixes applied are:
 

* cntlmonAPI - fixed parsing of non-standard dso
* ligolwAPI - added code to handle ligolw time out and testing on tandem-iii
* eventmonAPI: - removed extra killJob call; added capture of thread states
  for dataRecv to debug missing objects from wrapper.
* cmonClient: - working on all pages to be created when as needed rather than
  at startp and to reset only as needed.
 

There are currently 175 non-closed problem reports on LDAS of which 166 are
software and 19 are hardware issues.
 

Hardware Systems (Anderson)
No report this week
(AL note) However, the status of the CIT production system can now be viewed at the following URL:
http://ldas-gridmon.ligo.caltech.edu/ganglia/?r=day&c=CIT&h=&sh=0
This tool was adopted from the GriPhyN development effort and is being used by a
number of grid projects with large clusters.
 

Data Analysis Activities (Lazzarini)
Mendell:
The StackSlide code has been updated to better estimate the noise to
improve calculation of SNR. (Options were added to remove peaks from
noise estimation; an option to use the running median will be added once
the LAL code for this is ready.)  I also added the option to output a
Hough number count instead of StackSlide power. Validation and
benchmarking are going well so far, good enough to get preliminary
results for the LSC meeting. Much more work will be needed (along with
Monte Carlo studies) to get final results. I also added updated
documentation in README_ComputeStackSlideSums and
README_CommandLineArguments to the lscdocs/pulgroup/stackslide cvs
archive; eventually all will get moved to LAL and LALapps.
 

Shawhan:
* Prepared report about Matlab for the Data Analysis Software Working
Group (DASWG).
* Generated list of S3 time intervals, for each interferometer, during which
pulsar injections were on AND the interferometer was in science mode.
* Tracked down a recent problem with conlog as being due to the fact that
the /cvs filesystem on the LHO CDS cluster filled up, causing file
corruption.  Repaired the files and index to a self-consistent state.
 

Sylvestre:
o Worked on running tfclusters on the full S2 data.
o Checked that the Poisson hypothesis for the background noise was right.
o Generated triple coincidence datasets for the r-Statistics analysis,
worked towards tuning the false rate of the triple coincidence analysis to
maximize efficiency.
 

Weinstein:
- Worked on report on LDAS for DASWG
 

Yakushin:
1) Continue running simulations on the whole S2.
2) Preparing presentations for LSC meeting.
3) Trying to use Shourov's linear prediction filters with waveburst.
4) Regenerated all sky black hole merger MDC frames after Patrick Sutton discovered that they were actually half sky.
5) On Erik's request working on generating MDC frames with events injected not only at zero time lag but at time lags that are multiples of 5 s.
 

Lazzarini:
*       Finalizing paper on optimal combination of H1+H2 for use in stochastic searches;
*       Started work with the calibration team on the generation of time-domain h(t) frames. These will be a new class of RDS frames,
RDS_Cvv (C for calibrated, vv for version of calibration). I am writing a specification for these frames with the calibration team. Intent is to have something to circulate by the LSC meeting. The calibration team is preparing a presentation at the LSC meeting on this subject. Document
number is T040026 (not yet in DCC).

LDAS System Administration
--------------------------
 

Caltech
-------
(Dan Kozak)
 

* Continued to focus on getting data out of HPSS and into SAM-QFS.
 

* Worked on getting hpssmvr2 back online, first by working on it
myself,
  then by trying to get the other HPSS support staff to work on it,
  both without success.  Finally figured out a workaround and continued
  copying data.
 

* Dealt with an outage of the STK silo and worked with STK to resolve
it.
 
 

(Al Wilson)
 

* Tested NIS+ client with fedora. The RPM build that I have for RH9
  worked just fine.
 

* New firmware installed on the switch in Millikan. This firmware
allows the
  switch to work with copper Gig-E gbit. Tested, and this does allow
these
  adapters to work. But we still have the auto sense problem with
copper
  Gig-E.
 

* Doing some HTML editing with the BB home page for CIT. Trying to
create a
  one page overview of the systems at CIT.
 

* Replaced disk drive on datacache3 and 5. These systems are back to
full
  working order.
 
 

(Stuart Anderson)
 

* Worked with Sun to fix memory problem in V880 at Caltech
 

* Worked with Foundry to hopefully solve a network switch
  lockup problem in the large LDAS-CIT cluster.
 
 
 

MIT
---
(Keith Bayer)
 

* Ordering replacement harddrives for cluster machines.
 

* Getting dns entries for condor hosts.
 

* Replaced bad hdd in pcraid1 and rebuilt fs raid.
 

* Adjusted diskcacheAPI to read data shifted over to
  pcraid1a/1b from other pcraids.
 
 
 

Livingston
----------
(Igor Yakushin)
 

* The power panel's unfortunate property to physically disconnect power
  to LDAS in response to short outages has been fixed by Rusyl and
Excel:
  it is now powered through LDAS UPS.
 

* Requested IP addresses for grid computers.
 
 
 

Hanford
-------
(Greg Mendell)
 

* My LDAS sys admin work this week is a continuation of testing the
v1.0.0
  release of LDAS with the createrds process, and setting up archiving
and
  reducing of 1000 seconds of data every 100,000 seconds during the
postS3
  period.
 
 

(Ben Johnson)
 

* Completed most of the Condor harware/network setup. Including 4 new
  DNS entries for the condor computers. ldas-grid and ldas-gridmon have
  been set up as has autofs on the nodes.
 

* Backup scripts have been successfully tested at LHO. Next step is to
  setup LLO to perform the backups, or perform any usage modifications
as
  necessary.
 

* Continuing work on data corruption. We believe we're seeing the
  smoking gun, but we'll try doing more analysis next week on the DAQ
  system itself to confirm our findings.
 

General Computing (Wallace)
MIT:
(Keith)
-Spec-ing out new gc mail server
-Spec-ing out new cad pc for Ken
-Added urops to gc:
  Philip Richerme
  Matt Abernathy
-Removed several old accounts from gc
 

Livingston:
(Shannon)
-Current bandwidth usage can be seen at
http://teche.ligo-la.caltech.edu/mrtg/LLO-Router/130.39.245.1_1.html
-Archived bandwidth usage can be seen at
http://teche.ligo-la.caltech.edu/mrtg/archive/ under the dated folder
for the week of interest.
-Finished moving all of the home directories to the new file server.
I began moving them manually and realized it was going to take too
long, so I wrote a script to move the directories and update the NIS+
tables. The script took 2 1/2 days to complete so I would have been
there forever moving the directories by hand.  All of the home
directories are now on the  RAID server.  Still have a few things to
finish up, but for the most part this is complete.
-Set up two laptops for Bonnie and Katrina to use for two tours this
week.
-Set up a replica NIS+ server to get ready to move more stuff off of
our old file server.  Had some issues in the middle of this, since the
UPS that baronne is plugged into had some problems during the
replication.  It caused NIS+ to crash, then the machine was not stable
and I had to reboot it.  Commands like ps would hang and never finish.
Luckily, the NIS+ tables were not corrupted.  The last time this
happened it took us over 12 hours to get everything back.  Once I got
everything stable and running again with the replica server running, I
decided to leave things alone for a while.
-Promoted the replica server to be the master server, removed baronne
as a server, and then created a new replica server for redundancy.  The
old NIS+ server is now a client.  The mail server (abundance) is now
the NIS+ server and touro is the replica.
-Installed a tape drive on abundance to back up the mail spools and
the system.  Set up a script to run ufsdump nightly to the tape drive.
Later this will be set up in a different fashion, but this will give us
backups for now.
-Still working on compiling more apps and moving the old ones to the
new file server.  Need to make sure that when I compile things that
they do not link to libraries in /usr/local since not all machines will
have the same packages.
-Set up another ntop server so that I can monitor bandwidth usage.  I
will later be setting up snort and ACID on the inside of the firewall.
The new Cisco 3550 works great for this and is much more flexible than
the old PIX.  I can now span ports and use them for IDS purposes.  I
could not do this with the PIX.  However, the PIX will be useful when I
internalize the PCs.
-LSU contacted me about the old T1 router.  I think it is safe to say
that we will not need it anymore.  I have e-mailed them and told them
that I can return it since it is in their inventory.  I also contacted
Ric Simmons and asked him to turn off the T1 lines permanently now
since the GigE has been stable for the most part.
-Put in a request for 4 DNS changes for LDAS.  They are adding 4 new
gateways into the LDAS network.  In my opinion this violates the
"spirit" of the LIGO IT security plan, but there is probably not much
that can be done about it.  I count the number of gateways to internal
networks to be at least 12 now, though I am sure there are a couple I
am not thinking of off the top of my head.  This also puts the number
of operating systems at 4.  Many of the gateway machines do not have a
clear administrator responsible for the machines.  The only layer of
defense is the firewall and for some reasons this is not sufficient at
this point.  I am concerned that this will only get worse.
-Dell has provided a fix for the problems that I was experiencing on
the new Gigabit switch.  I have not implemented it yet, but it involves
a filter being put on our Foundry core switch.  Hopefully it will fix
the problem since I am only able to use 2/3 of the ports on the new
switch.  So far I am more pleased with Dell's support than I am with
their hardware.
 

Hanford:
(Christine)
- Purchased the yearly maintenance contract for Matlab.
- Put in a PR to buy 5 Sun blade 1500s.
- Notified users of a disk full problem, requested they clean up their
unnecessary files.  I was also able to move some user directories to
another disk to make more room.
- Over the weekend a disk containing user directories died.  I had spare
disks and everything was backed up to tape, so I was able to fully
recover in only 2 hours.
- Everyone received multiple emails containing the latest viruses.
Thanks to all the reminders and announcements from Caltech and Sysadmin
we were able to come through this latest round unscathed.
- Worked on a user's pcard problem.  Something in the registry or
software files has become corrupted.  The pcard is looking for a file
that doesn't exist and it won't run without it.  Multiple reinstalls of
the software have not fixed the problem.  Still trying to fix it.
- A user complained of multiple virus containing emails being sent to
him via Caltech ITS servers.  I contacted Caltech ITS, their spam/virus
filter was not catching that these emails contained a virus.  ITS agreed
to block the originating IP address, which came from an ISP in France,
and to notify the technical support at the ISP.
- Other misc. user support.
 

CIT:
(Mike)
-Worked on a few computers that were infected with viruses. This was the
W32.Beagle.B@mm & W32.Netsky.D@mm, W32.Netsky.C@mm. I have cleaned these
viruses with anti-virus removal tools, cleaned up the registries and
deleted other trails that were left behind from these viruses.
-I work on Calum Torries computer troubleshooting his solid works installation.
Every time he works on a drawing it ends up crashing. I have looked for
viruses and came up with nothing. I then installed a current service pack for
solid works and am testing this right now. This is looking more like a video
card incompatibility issue with solid works.
-Backup all NTSRV's for an end of month backup. I also included the PDMWorks
server.
 -Loaded firewall software on Florence, Dot and Ryans computer. I have a list
generated by Larry Wallace, on who is to have this software loaded. I still
have many more users to load this software on.
-Moved some equipment around with Larry to make room to store additional
computers and monitors, down in the sub-basement.
-I removed a workstation from DCC that is being reloaded for Bob Taylor over in
40 Meter. I am just about finished with this PC and will be swapping out
Bob early next week.
-Swapped over Ruth Brambila & Easter Cunningham to the ITS network. This was due
to an authentication problem that these users were having upon
logging in to the Business domain, located on the ITS network. This was taking
anywhere from a œ hour to an hour just to login going through the LIGO
network. Plus there were many other issues they were having on the LIGO network.
Everything seems to be running smoothly now.
 -This is another week of many onsite and phone user support that included
printing and software issues. I check out many computers that users had
questions with on the latest round of viruses. The majority of our users are
doing great job on being conscientious when receiving e-mail with attachments
from unknown users or even legitimate users with strange attachments. Any
questions on strange e-mail, please do not hesitate to call General Computing.
 
 

(Lisa)
- Spent most of the week getting the acrux replacement server tested and ready
to go online.  This included upgrading becrux so that the 2 servers can use the
same spam database.
- Have started digging into the details of clamav, the virus software that will
be running on the mailservers henceforth.  Since clamav is an open source
project, updates may occasionally include checking out the code from source.
- Looked into using logrotate to manage the logs on the mailserver.
Unfortunately, it doesn't work.  Am going to look into rottlog next.
- Helped Larry chase down a couple of infected pc's.
 

(Veronica)
- CaJAGWR: Recorded the video of the last talk by Adam Burrows. Addressed
issues of remote participation from Hanford; at the end LHO decided to go
with a dial-in and indicated they might be interested in a webcast in the
future.
Compressed and posted the video of the talk. Adam had a lot of animated
simulations in his talk, and I am trying to compress them to add to the
posting. Updated the seminars webpage and provided user support. Burned
the 2004 talks on DVD and sent off to LHO, as requested by Vernon
Sandberg.
- LSC web: Posting the MOUs/PRs as they keep (and keep and keep) arriving.
Updating the March meeting website. Working on the Contact Information
webpage of the collaboration.
Installed a webpage for motions to be discussed at the upcoming meeting.
- LIGO: Usual upkeep. Assisted Calum Torrie in choosing the navigation for
a webpage on which he works. Provided a set of scripts for him to try.
Prepared high-resolution images per a request from Caltech Media Relations
office.
Updated seminars webpages.
 

(Larry)
-This has been an interesting week with the viruses that have been going around.
We've had a number of machines that have been infected through a backdoor on the
machine. They have all been taken care of.
As for the users they have been great. So far no major incidents from someone
opening up an infected e-mail message. Many have contacted us(the sysadmin
group) concerning suspicious e-mail messages which is the correct thing to do.
-Spent time with Shannon going over a number of items he is working on at
Livingston. The NIS+ issue did work out in the long run but for a short time it
looked like it was going to be a show stopper.
-Worked a number of printer issues. A number of them were paper jams but others
appear to be the drivers on the computers needing to be reset in-order for the
print to come out correctly. Still have a few drivers to setup for the E2E
machines.
-Worked on a couple of the E2E servers to get them back into correct working
order.
-Helped a couple of people out with licensing issues.
-Setup a second audio enabled webcam. Reprogrammed a couple of webcams.
Presently, we are doing some testing on the units. The one thing that is a
problem is that so far we can only get the audio from the webcam to work under
IE. This is something we will continue working on to try and find another
solution.
There will be one audio webcam setup for checkout. We are getting the full
package put together and it should be ready by next week.
-Ordered a number of computers and related items. Working on get a couple more
SUN orders out.
-Albert informed me that there is a new update for the VRVS but we have not had
time to test it out yet.
-Worked a little on some of the engineering pkgs. being used. This is something
that will probably need more support in the near future.
-A lot of regular user support.
