Agenda

Analyzer code updates

  1. General discussion
    • Do we want the aggregator to be aware of file splits?
      • We probably should change the options for the engine to combine file splits. This would produce a single set of outputs. The rootfiles could end up getting split, if we take very long runs.
    • The prompt summary class initially had a bunch of hardcoded things, such as the pattern size
      • I would suggest having the prompt summary class directly request those values from the internal data objects, rather than having another parameter file which could become mismatched.
      • Cameron had made a series of log entries about what was needed to be done when we switched to 240Hz, so we can refer to them: Changing to 240 Hz summary notes
    • There have been some issues with doing widcarded "rm" operations of png files within the prompt scripts, and having this bogging down.
      • Maybe we should change the prompt script to produce the pngs into a temporary directory that we could just do a "rm -r <tempdirname>"
      • Cameron raises a question about using the ROOT "dataframes" mechanic.
      • Maybe we can use the engine's histogramming functionality for some things?
    • Analysis-minder is hanging sometimes
      • I'll try to look into it with Robert this week
  2. New feature plans
    • Continuing development of minirun functionality
    • Data-handlers which can process results from other data-handlers
      • Robert had been working on getting the "prompt" analysis chain working on the farm machines
      • Robert and I will pick up the data-handler-handler this week
    • BMW first pass extractor
      • Hooks are in place for an event-level data handler.
      • Wouter was going to set up a prototype general-purpose data extractor (selector), then hand off to Cameron: it just requests either specific variables or looks at the ErrorFlag and writes to a tree based on the values.
    • Issue #207: Cameron will follow up

Prompt analysis toolchain

    • Robert was having issues with file system permissions in getting the tootlchain working on the farm machines
      • I will follow up with him and Cameron later today.
