Site and other Business Issues:


Special Announcements: The NSF included Advanced LIGO in their 2008 budget request, a very significant step forward for Advanced LIGO. It is the result of the hard work, but more importantly the high quality of the work, being done on Advanced LIGO and in the LSC more generally.


Weekly Report Highlights: LHO operating routinely above 15 Mpc!


LSC Issues (Saulson)

The S3/S4 known pulsar paper was posted to gr-qc and announced to GWIC. We are now waiting for two weeks for comments, and then will submit the paper to the journal. The S4 stochastic radiometer paper is about to be posted.

We have opened registration for the March 19-22 meeting of the LSC and Virgo Collaborations, our first joint meeting. Please register soon, if you haven't already.

Shortly after this week's meeting of the Virgo Steering Committee, Virgo and the LSC will formally appoint the joint Data Analysis Council, and also the joint Run Planning Committee. Those are the two bodies that will, when the time is right, make a recommendation to the two Collaborations to start data sharing between the LSC and Virgo. We hope those two bodies will start discussions soon.

Quality/Safety (Tyler)

>From: Bill Tyler tyler@ligo.caltech.edu

The last LIGO campus safety audit (40M Lab) is scheduled for Friday.

The LDAS Computing and LIGO Server Facilities safety audits were conducted earlier this week.  The audit team was pleased to find no significant safety or "housekeeping" issues during the audits.

We are working with the Advanced LIGO Project to establish a consulting contract for high power laser safety support.


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

Summary of S5 Activities at LIGO Hanford Observatory (compiled by K. Kawabe)

Peaceful week with solid performance after successful commissioning break.

Duty cycle (Thu Feb/1 to Wed Feb/7) of H1 was been 92.9 percent with 14 - 15.5 Mpc inspiral binary range. For H2 it was 92.8 percent with 6 - 7 Mpc range.

Summaries: Range and Duty Cycle update. Tuesday maintenance summary.

Highlights from the LHO elog are listed below:

LIGO:

  • Attempted to track source of IFO noise introduced when CDS EPICS backups are performed at LLO, normally once each hour. Even when running concurrent, multiple backups, we could not get noise to appear. So, for now, we will continue to perform backups only when not in science mode.

TCLGLOBUS

Mary Lei and Michael Samidi are still setting up
ldasbox1.ligo.caltech.edu (64-bit machine) instead of
ldasbox4.ligo.caltech.edu (32-bit machine) for running valgrind
to investigate LDAS managerAPI coredumps using Globus threaded
libraries.

Still investigating GSI authentication failure on Opteron systems.
Michael Samidi is still working on providing more details to Globus
team for Bug #4946. Tested with OpenSSL from command line and it
seems there is certificate misconfiguration.

OpenSSL memory leaks within Globus Toolkit 4.0.3 has been addressed
in Bug #4743 (http://bugzilla.globus.org/globus/show_bug.cgi?id=4743).
Michael Samidi will find out if this bug will be included in Globus
Toolkit 4.0.4 (est. March 2007)


GRID APPLICATION DEVELOPMENT:

Testing several OSG sites (PSU, Purdue_ITaP, UWMilwaukee, Fermilab and
STAR_BNL) for meeting the second OSG milestone, running LIGO workflow
on OSG with 100 or more CPU slots for one week.
After running 2 days (Feb 5 - Feb 6) with 100 or more CPU slots, all
workflows died at 7 PM on Feb 7, 2007. This could be due to bug
discovered in the latest Condor version (6.9.x) installed on
osg-itb-se.ligo.caltech.edu.

Still testing full HIPE at LDG CIT cluster with job clustering with
a new Pegasus property to enable sysmlinks and third-party trasnfer
at the same time. Submitting HIPE workflow to ldas-grid is still
causing high load on the gatekeeper. This is due to the workflow is
submitted through Condor-G. Michael Samidi is still working with
Karan Vahi to investigate the problem.

Completed moving LIGO GWFs from CIT repository to UCSD SRM server.

Still working on SRM problem at UCSD with Karan Vahi.
The problems are submitting srmcp jobs using Condor-G fails
and missing a single quote surrounding SRM URL in the submit
script.

OPEN SCIENCE GRID VALIDATION TESTBED

Attended VTB telecom related to CEMon problems

OPEN SCIENCE GRID INTEGRATION TESTBED

Validated one additional ITB sites with nanoHIPE application.

Installed Condor 6.8.4 after bug appeared in Condor-G 6.9.1 on
submit host. Upgraded TclProxy host to be a second Condor-G
submit host to allow more jobs on the OSG.

Reorganized ITB Twiki SiteValidationTableITB052 to segment
sites based upon capabilites and functionality.

Continued to test new fixes provided by FNAL developers of
CEMon.

Worked with Michael Samidi and Kent Blackburn to refine
submission sites for OSG milestone.

Successfully tested ws-gram interface on LIGO-CIT-ITB.

Attended weekly DASWG, ITB and Pegasus telecoms.

Duncan Brown

- Continued to generate more numerical waveforms and work comparison
between these and post-Newtonian templates.

- Found and fixed bugs in the LAL 3.5pN inspiral phasing code.

- Constructed a set of data quality flags that can be used to perform
a blind hardware injection challenge on the 1 calendar year BNS run,
as a prelude to the real blind challenge.

- Worked with Drew on S5 1yr search.

- Worked with Diego in implementation of physical template family.

- Helped Patrick with some xpipeline work.

- Release a new version of glue.

Gregory Mendell

I have generated more "fscan" spectrograms and spectra of channels
during times from last month's commissioning period when Robert
Schofield connected ripple boards to various power supplies. The latest
elog is here:
