P106 Reprocessing

status: Indefinite HOLD Complete
last update: 13 May 30 June 2010

This page is a record of the configuration for the P106 reprocessing project. It targets 200 runs of L&EO data for processing with a new alignment calibration and other improvements to investigate issues with the Pass7 classification.

...

  • P106-LEO-MERIT - this task reads DIGI, runs the full reconstruction code in Gleam and produces reprocessed RECON + MERIT + CAL + GCR P106-LEO-FITS - this task will read MERIT and produce FT1 (photons)+ FT1

Datafile names, versions and locations

The currently defined data sample for P110 and P110-LEO reprocessing includes:

Total MERIT events

484,421,935 ~488M

Total FT1 events

Note that the L&EO data represent a discontiguous set of runs.

P106-LEO-MERIT

Status chronology

  • 29 June 2010 task continues with little impact on xroot/nfs servers (at least as ganglia is concerned). But wait. The processClump step ran without undue stress on xroot, but the mergeClumps was not so lucky. Both of the newest wains (60,61), which are 12-CPU machines, both got overloaded and lost contact with the world, as shown in the Ganglia plot.

    By 21:00 task complete.
  • 28 June 2010 14:15 - begin full task...slowly
  • 27 June 2010 - update task with new calibration flavor, add back in 200th run, and fire off test stream (4)
  • 11 May 2010 - Prepare task
  • 13 May 2010 - four test streams submitted...formally successful. Anders has given cursory glance at first few events of first stream (recon/merit only) and the log file, saying all looks okay. However, it has been discovered that the alignment issue thought to be an issue with the L&EO data is a non-issue. So put this task ON HOLD.
  • 11 May 2010 - Prepare task

Configuration

The configuration for this reprocessing is nearly the same as for the ordinary science data with three exceptions: the run list was provided by Anders (and consists of a discontiguous set of runs); fewer data products are produced; and, the algorithm for finding FT2 files was modified to accommodate these earlier data (in fact, Warren produced a new set of 1-second FT2 files specifically for this reprocessing project). Note that the original list of runs counted 200, but a single run proved troublesome, 238781852, and was removed from the list, leaving 199 runs to reprocess.

Status chronology

Configuration

...

All 200 runs were fully reprocessed within 30 hours elapsed time. A longer task will not necessarily scale from these numbers, as this elapsed time includes all phases of the task: ramp-up, steady-state, xroot troubles, ramp-down, clean-up. In addition, for the first part of this reprocessing the heavy-lifting jobs were run in the long batch queue which at the time had a per user limit of 1000 jobs (this has subsequently been changed to 'no limit'). The latter part of the task was run in the xlong queue which had no per user limit - but a global limit of 3000 jobs.
