[Users] Meeting Minutes for 2014-11-24

[Roland Haas]

Present: Frank, Roland, Ian, Matt, Erik

Post release tickets:
* #980 "Remove support for felsh base library mechanism": Ian with help
* #1642 "GRHydro should not depend on ADMMacros": Roland
* #1698 "The ET tickets should be tidied up": want proposal on how to
proceed on wiki page, Ian has already created such an one and will
update it until the next call so that we an discuss it
* #1252 "Thorn configuration scripts should not be run if there are
missing thorns":
** problem is related to build of ExternalLibraries takes a long to finish
** conflicts with desire to collect all errors in one place and report
them once
** suggestion to have early check for missing thorns, this may be
possible early on since all configuration.ccl are parsed before CST
build begins
** preferred solution is have two-stage build of ExternalLibraries
however we lack a volunteer with time to implement this
** Frank will look at the short term solution
* #1490 "ExternalLibraries/PAPI contains testsuite, but no data":
assigned to Peter
* #1518 "Parameter parse and CCTK_ParameterSet interpret leading zeros
in numbers differently": assigned to Steve
* #1537 "Deprecate complex number functions": Roland will take care of
updating the documentation and hunting down ET thorns that use the old
functions
* #1595 "Is *) allowed as upper boundary for a parameter range?": change
the parsers to allow flexibility where unambigious ie. accept *) in
place of * . Update Kranc to produce *:* instead of "*:*".

Staggered vector potential operators:
* current implementation is not yet ready to merge into master
* would like to have branch that is ready to merge, ie a proposed solution
* preference for having all vector field components in a single groups
* suggestion to allow staggering to be defined per variable in Carpet
and eventually in the flesh

Duplicate stdout output into CCTK_Proc0.out:
* hard to implement tee-like functionality in C
* compromise on having extra option to also redirect stdout and stderr
on rank 0 when -redirect is specified

Plans for next release:
* discuss next week
* Frank has some thorns that he'd like to make public
* AEI svn server likely going to be reinstalled, thorns accessed from ET
may migrate to git and bitbucket into an "External" repository of Cactus
for the non-GR related thorns

Yours,
Roland
