+== IPP Progress Report for the week ending 2009.09.06 == 
+
+(Up to [wiki:IPP_Progress_Reports IPP Progress Reports])
+
+Most of the IPP team were at the meeting at Harvard last week, so not
+a lot of progress was accomplished.  We had a major incident on the
+MHPCC cluster, losing the RAID that hosted the home directories.  The
+RAID was recovered eventually, thanks to Brad, Cindy, & Gavin, and in
+the processed we learned that the drive bays are mis-labeled. In the
+mean while, we took the opportunity to re-assign the home directory
+machine temporarily to ipp053, with the goal of moving to a pair of
+mirrored 1U compute nodes.  We'll need to buy some raid hardware to
+make that a easy-to-recover setup, but it will mean a more reliable
+home directory in the long run.  This also gives us the chance to fix
+or address the drive bay in ipp004 that is inactive (we've been
+running at raid 5 as a result for > 2 years).  There is still some
+re-organization work needed, which was made difficult to arrange with
+nearly the whole team gone to Harvard, but that should be finished by
+early the coming week.
+
+For my part, in addition to recovery from too much travel, I've been
+working on the extended source analysis.  I'm now fairly happy with
+the radial profile extraction + petrosian analysis, and I'm
+incorporating it back into the psphot code base.  I'm also making some
+tests and fixes at a low level of issues that have been reported
+lately, including some trouble converging on a good 2D psf model.  the
+coming week, I will continue to focus on psphot.
+
+Paul Price:
+
+* Cluster woes
+ + Checked operations pantasks scripts into repository
+* MOPS support: branches/pap_mops/
+ + Revised publish_file.pl to support revised ppMops, following "ICD
+lite"
+ + System working again
+ + Republished ThreePi_SouthernRegion.090818 and
+ThreePi_NorthernRegion.090818 to MOPS
+ + Merged into trunk
+* Destreaking: fixed doCopyExtraExtensions in streaksremove --- wasn't
+actually doing the write, wasn't setting compression appropriately
+* Detection efficiency: branches/pap/
+ + Got first cut of code done
+ + Discovered psphotSignificanceImage doesn't seem to be using correct
+smoothing size: decreased sensitivity, but not too bad?
+ + Finally worked out how to calculate rough limiting magnitude
+ + Working now, next concern is formatting for output

+Bill Sweeney
+During the week ending August 28 bill worked on improving the
+performance of the postage
+stamp request processing. This led to a factor of 10 improvement for
+typical MOPS
+request.
+
+He spent the week ending Septmber 4 at the PS1SC conference in Cambridge.
+
+In the upcoming week he will be 'releasing' the IPP postage stamp
+server to the consortium.
+
+Heather Flewelling:
+3 weeks ago
+*culled a few million raw science files. I hope we never have to do
+that again. Learned a few more things about nebulous in the process.
+
+2 weeks ago
+
+*contacted Natalia. Gave her instructions on compiling ipp and some
+links to read on dvo for when she gets an account on the manoa
+cluster.
+*worked on dvo stats for smf/cmf. Started writing macros to make dvo
+more idl like, but also useful for the dvo stats I'm working on.
+Should be useful for other ipp-users.
+*investigated other raw images files with >2 copies
+*investigated raw image files with <2 copies that are not replicated
+(caused by ipp008 being pulled out of nebulous and the raw image files
+not having the proper xattr bit set)
+*flew to boston for conference
+
+last week
+
+*Attended panstarrs conference in boston
+*ate lobster for the first time
+*met with harvard
+*installed ipp on my mac laptop
+**forced cfitsio, libtool, and libjpeg to install, coped glibtool to
+psLib and psModules directory (renamed to libtool, thanks to a helpful
+hint from our consortium members from NCU), and hacked a few of the
+header files to make it work. Probably forgetting a few other things.
+Not pretty, but it works.
+*spent thursday and friday in michigan (go blue!!)
+
+Bill Giebink:
+*Continued working on psLib tap tests throughout week
+*Restart and maintenance of DIMM on Tuesday
+*Observed with Natalia Wednesday night
+
+Chris Waters:
+- Changes to ppImage to allow optional masking of unfit burntool
+ trails as well as pixels repaired by burntool.
+
+- Harvard meeting.
+
+- Began investigation of spurious transient sources noted by Armin
+ Rest to determine if they are really caused by burntool, and whether
+ ppImage masking could fix this.
