[Users] Meeting Minutes

[Tanja Bode]

Present: Frank, Steve, Eloisa, Ian, Tanja, Erik, Josh, Bruno (did I miss anyone?)

Minutes:

  * Reminder: Loni allocation changed from loni_cactus07 to loni_cactus08
      See meeting announcement and emails to lists.

  * Parameter files:
      Small representative parameter files are requested. These should not 	
      necessarily be confinable to a workstation, but should not require many SUs.
      There is a growing list at http://einsteintoolkit.org/about/gallery . We should
      include typical simulated systems, with typical parameters. That is,
      simulations should include standard analysis thorns and output choices. These
      should also show the typical yet diverse practices, e.g. of handling output
      directories and checkpointing files.

      We can adapt parameter files from the ET paper, but only some fit the above
      requirements. We need to clean these up, update them, and include details on
      resources required (memory, runtime, & thornlist). We should also expand the
      list from the ET paper to include more example systems to show what the ET is
      capable of.

  * CactusExamples:
      Currently part of the Cactus release but not the ET.
      https://trac.einsteintoolkit.org/ticket/809
      Erik will look at these one by one to see whether the demonstrated methods
      are ones we wish to push others to use. Somebody else will need to review.

  * TmunuBase:
      Default of support_old_CalcTmunu_mechanism is currently "yes". Frank will
      change the default to "no" after call in development since it slows down
      simulations. Removing support completely would break BSSN_MoL among others, so
      this will be discussed later.

  * Compiler Warnings:
      Please look at the compiler warnings and fix. Still of order 1000 lines of
      warnings with Frank's compiler flag settings. See the following graphic for
      current flag status:
