[Users] Einstein Toolkit Meeting

[Frank Loeffler]

Hi,

Todays minutes of the Einstein Toolkit Meeting:

- attending:
 LSU: Frank, Dennis
 RIT: Joshua
 PI: Erik
 Caltech: Philip
 AEI: Eloisa

- Einstein Toolkit Workshop
  Time and location are not decided yet, the doodle poll for the time
    http://doodle.com/ritukz79hhuvhben
  is still open, and so far LSU (Frank) and RIT (Joshua) volunteered to
  host it, but no other opinions have been raised.
- CoordGauge was added to the 'potentially to be removed' component list
    https://docs.einsteintoolkit.org/et-docs/Usage_poll
  Please add more if you can think of something that fits and please
  comment if you think something there should not be removed.
- It was pointed out that a new version of Cactus was not released
  with the last version of the ET (but a corresponding release branch
  was created). Expect a new version of Cactus probably sometime within
  the second half of this year, maybe again coinciding with the fall
  release of the ET.
- Planned, larger changes to Cactus (especially the flesh) include:
  - Some better support for Mojave (the Cactus Eclipse plugin)
  - Expect to have to use lssh instead of lsh in the future to be able
    to use padding of grid functions.
    - lssh is the size of a GF as seen from a users point of view
      (How much was requested in the parameter file)
    - lsh is the actual size of the GF in memory. This might be larger
      than lssh and thus, contain unused points. While this uses more
      memory it can make execution faster in some cases.
    lssh and lsh always had that meaning, but so far they simply have
    been always the same and people got used to use lsh instead of
    lssh in places where lssh should really be used - so some thorns
    will need to be changed.
- Roland Haas will host the ET meetings from next week on until the end
  of July.

Frank
