Present: Zach, Steve, Roland, Peter, David Bradley, Maria, Ken Sible, Leo
Werneck, Liu Haoyang, Miguel Gracia, Sam Cupp, Bill Gabella, Yosef
- *SPEC benchmark*: Steve reports no progress, but says we should do it.
Roland wrote a to-do list for this task:
https://bitbucket.org/einsteintoolkit/tickets/issues/2470 . Some details
regarding this to-do list were discussed.
- *Webserver issues*: einsteintoolkit.org was down for ~70 hours
(including Dec 5-6 weekend).
- Roland: was it a glitch or something systemic?
- Steve: glitch. Machine hosting virtual webserver went down -- just
needed LSU CCT support to reboot machine. Will work with Roland
& Peter to
ensure there's more redundancy in the future. After ticket, machine was
back within an hour.
- Bill: cactuscode.org has problems redirecting to new github.io
page. Roland: Only sometimes, and not with Chrome. Firefox indeed doesn't
redirect unless www.cactuscode.org is used. Roland: *Always* use
*www.cactuscode.org
<http://www.cactuscode.org>*
- *Updates for next release*:
- POWER: Used for waveform extraction on Scri+ -- Maria & Zach are
interested in this code. Roland is improving interface, etc.
- GRHydro con2prim updates -- Roland: A number of improvements have
been reported from various groups.
- selfforce1D updates -- Peter: new features are in progress,
depending on progress might be a candidate for inclusion
- Canuda updates -- Roland has been in touch with authors, privately.
- *Unanswered mailing list queries*: One MPI query (failure) discussed,
will need more details to help. Peter said he'd send an email.
- *Tickets*:
- #2335 (
https://bitbucket.org/einsteintoolkit/tickets/issues/2335/switch-simfactory-to-use-python3
) Steve: Patch makes SimFactory compatible with Python3. Pull request
ready for review. Bill said he'd test it out. Roland has started
to review.
- Roland: other tickets ready for review, nothing super urgent at the
moment.
- *NRPy+ LaTeX parser update*: Ken Sible reports ability to now parse
another of the BSSN equations. \gamma and \phi (using W variable) can now
be parsed. Continued robustness improvements. Hope to have remaining
equations parsed within the week. Bill asked for a progress report on
parsing non-tensorial expressions, like those in PN expressions. Ken: we're
very close to being ready to parse those expressions.
- *Tabulated EOS with single TOV star*: Some discussion on whether this
has been done with GRHydro. Roland pointed out a TOVHot code that may be on
stellarcollapse.org (
https://svn.einsteintoolkit.org/incoming/TOVSolverHot/); Miguel: RNS
thorn may have a parfile with tabEOS as well, could try out (HydroRNSID:
test/RNS_a2.par).
- *Jan 7 meeting*: Minute taker: Bill. Chair: Maria
-Zach
