Agenda

New issues

  • Devi asks about getting an updated overloaded postpan for certain runs to include ATs. Tao had tried to do this, but ran into directory permission issues. Probably *Robert* needs to run a chmod g+w in the output directories again.

Analyzer code updates

  1. Issue 269: diff* variables are missing in burst and muls trees
    • This is a labeling issue; Paul has a fix in testing
    • Paul will try to get back to this issue to see where he was in the testing


Other issues

  1. Cleanup of the web directory for plots
    • We should also be able to get rid of the files like "run####_###_all.pdf" that are in the individual run subdirectories under the prex2/summary folder, as those PDF files are the concatenation of the other files in the directory.
      • Robert will set up a script to check that the individual PDFs are present and then remove the "all" PDFs
  2. Missing output files from the respin
    • Devi had sent the list of runs that he had found missing output files to Robert. It seems like one or two runs in each slug.
    • Sakib will work on developing a script to systematically check all the runs in the run list.
  3. We should add a web directory for the PREX AT data, and do a respin for them
  4. We should start following up on cleaning up unnecessary files from the chafs2 work disk (where the prompt root outputs go). I also saw an alert about disk space on the chafs1 work disk; I think this is mostly used by the polarimetry group so I'll let them know.

Data sizes as of today

  • Raw data (parity_ALL and parity_INJ files from run 3000 onward): ~10TB.
    • About 4.7TB is still on the adaq cluster (from about run 5100 onward).
  • Prompt pass1/pass2 rootfiles: 26TB / 16TB === 42TB together
  • PREX2 Respin 1, all directories: ~11 TB
