you.

Would it still be possible to include (commented out) the IllinoisGRMHD
code? This was in the minutes
http://lists.einsteintoolkit.org/pipermail/users/2014-April/003548.html
but apparently never actually done in the thorn list. I just tested a
modified thornlist (see attached patch) and it compiles and links (and
Zach tells me it also passes tests when compared to the older Illinois
GRMHD code).

We also have some thorns in there that are to be archived and a handful
of new thorns, see

http://lists.einsteintoolkit.org/pipermail/users/2013-December/003343.html

During the phone call we reached agreement to include:

* PAPI: want documentation, include
* MemSpeed: want documentation, test case, include
* dylib: include if compiles, WARN loudly if it cannot run at runtime
* F5: want documentation, include
* WaveToyCUDA: keep commented out, assuming testsuites and docs
* Boost: objections to size of repo. ran out of time to reach conclusion

During the phone call we reached agreement to remove:

* uncontroversial: move ADMConstraints into EinsteinArchive and replace
with ML_ADMConstraint which provides the same functionality. Reason:
ADMConstraints uses old Tmunu interface (optionally) which is deprecated
and will be removed. ADMConstraints also uses ADMMacros (is 4th order
only etc) which are hard to maintain (we also found a bug in 2010: r107
"Undefine the guts instead of the declare")
* uncontroversial: remove old Tmunu interface. Reason: eat up ~30% of
total CPU time since it contains a CCTK_IsThornActive in the innermost
loop
* uncontroversial: retire ADMCoupling since it is only used for the
deprecated Tmunu interface, FRIEND mechanism in Cactus is also no longer
advertised as good usage. Requires fixes in Exact.
* DistortedBHIVP, IDAxiBrillBH, IDAxiOddBrillBH, RoatingDBHIVP: mark as
archived using comment. Remove from manifest (comment out) if tests
fail. There are objections to moving the repository.

Retiring ADMCoupling at this stage may not be possible unless we already
have the fixes for Exact in.

Yours,
Roland
