Meeting Notes

• Q/A

• Fixing issue with changes to spiderT.lua format

  • To support the new hide{} functionallity the hide key changed from hide = true to hide = {kind = 'hidden'}.
  • Code added to convert old way to new

• Work continues on support for non-reversible functions:

  • setenv{"A","B",mode={"load","unload"}}
  • prepend_path{}, append_path{}, ...
  • working on getting this to work: load("moduleA","moduleB",mode={"unload"})

• Changes to tracking module usage:

  • Removing support for old python MySQLdb
  • Adding support for python3 module mysql.connector as replacement.
  • Change in lmod db format: one table w: user,module, path, date, syshost instead of 3 tables
  • Conversion tool to move from gen_1 to gen_2
  • The program store_module_data now takes a ignore.txt of regex lines for modules to ignore
  • Big change: Only record one module usage per user per syshost per ingestion file (typically one per day)
  • At TACC, I see a reduction from 100 times to 300 times.
  • Some users loaded our TACC module which include 4 to 6 other modules 300 times or more.
  • A program provided will remove old data
  • Lev requested that the reduction to one entry per day be optional

• Next meeting: January 14th
