[Users] Meeting Minutes

[Roland Haas]

Present: Frank, Peter, Steve, Roland, Erik, Matt, Ian

upcoming release:
* tutorial currently refers to QueenBee which will go away in 2 weeks
* will rewrite to tutorial to use Eric (also LONI) instead, once Eric is
ready for use
* will not hold release because of this

complex parameter files:
* apply patch #1554 [1] since it is only an incremental change of
complexity compared to currently implemented functionality
* including scripting language in Cactus is separate issue
** cannot call system() from within Cactus
** python is well known to users, but hard to include (Steve and Erik)
** lua is easy to include but not as well known to current user base
* option for declarative style file rather than imperative style (ie
setting parameters only once)
* would like errors to be detected as close as possible to line
introducing parameter error (so not first create parameter block then
verify once the script finishes)

* Ian to create ticket and implement code to have the Cactus flesh write
fully parsed parameter file with all options by default (in addition to
what is currently done). No objections to this feature.
* decide on whether to also generate (rather than copy) parfile with
only "set" parameter
* interested parties to come up with "mock" complex parfiles so that we
can then have a starting point for further discussion

Ongoing issues:
Gallery:
* small examples of non-trivial code
* BBH (qc0): Ian
* BH: Peter: working version on Peter's laptop
* NSNS to BH: currently fails
* TOV collapse: Roland was volunteered, but suspects this will fail

Yours,
Roland
