== IPP Progress Report for the week 2009.11.02 - 2009.11.06 == [[PageOutline]] (Up to [wiki:IPP_Progress_Reports IPP Progress Reports]) === Eugene Magnier === === Heather Flewelling === === Bill Giebink === * Jury duty Monday * Spent a small amount of time on realtest. * Did further study and preparation for starting DB replication. * Got Josh's arclog.pl script running to collect Areca RAID card logs from nodes. * Started parsing of logs to isolate read errors. * RMA'd two boxes of WD drives. * Started looking into buildtest and psLib TAP test failures. === Paul Price === * Dual convolution (branches/pap) * Merged into trunk (rr25999,26000) * Ran on 4 diffs from ThreePi_SouthernRegion with DUAL=T, SPATIAL.ORDER=0. Some strange results for a small subset of skycells; otherwise good. * Some bad subtractions, clearly identifiable with chi^2^ > 100! One has 25453.6! Cannot fix merely by increasing ITER. * Softening errors produces nice behaviour --- fixed! * Some sources show up in the subtraction that should be masked --- fixed. * Happy with dual convolution again, pending testing on a few exposures. * Stacking (branches/pap): investigating rejection behaviour * Completed rework of combinePixels * On each rejection pass, throw out only the most variant pixel; change iterations parameter to iterations per input. * Happy with behaviour of stacking (r26011): * 4 inputs from stack_id = 14006 (the Draper stack) * stack_id = 25532 (full Draper stack from more recent warps) * Would benefit from threading the creation of the fake images * Moved TEMP.DIR from ppStack recipe to site configuration; updated production version === Bill Sweeney === * Modified the distribution tasks to spread the bundles over multiple hosts to improve performance. * Split up distribution bundle processing script into two pieces so that it can be used by the postage stamp server for 'get_image' requests. * Worked with Gene analyzing faults and fixing problems uncovered in the throughput tests. (some of these problems were introduced by the previous two tasks. Sorry.. * Fixed a couple of postage stamp bugs reported by Ken Smith. * Spent some time doing research into techonologies for creating the real web interface to the postage stamp server * Ran simtest and fixed some bugs found there. * Looked at the results of the backround restore program. Found out that compression is not appropriate for the background model file. Turned it off in the file rules. * Marked trac tickets assigned to bill that have been fixed to fixed. === Chris Waters ===
