[Roland Haas]

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

open tickets
* TwoPunctures d3tensor patch: Roland to test Erik's patch in valgrind,
to report back
** hard-coding lower bound to zero would likely not significantly
simplify the code
* some version of subversion fail in parallel checkout
** Frank has written workaround
https://trac.einsteintoolkit.org/ticket/1395 needs review
* no objections against moving common GF tags into interface.ccl, Roland
to propose a list

Kranc changes:
Ian had replied to Roland via email and said:
--8<--
Here is a summary of what I have done:

• Developed some unit and regression tests for Kranc.  In addition to
standard unit tests which test individual functions (of which there are
few), I also generate small thorns and compare the generated output code
with the previous version.  I include cut-down versions of McLachlan in
their many forms (plain, vectorised, OpenCL, CaKernel, DGFE), as well as
several examples of specific features.
• Major long-overdue cleanup of the internals of Kranc.  The external
interface has not changed.  The only effects should be in the formatting
and ordering of the generated code.  Some items in CCL files will be
reordered and some variable declarations in the code will be made
slightly more consistent.
• Lots of very old code has been removed or rewritten.  A lot of "cruft"
accumulates over 10 years!
• Aim is to make Kranc significantly more modular; very long functions
have been broken up, and each "feature" has been moved to its own source
file (e.g. vectorisation, opencl, DGFE etc).
• Have taken a conservative and incremental approach to the cleanup,
ensuring that the tests pass after each small change.
• Still much left to do
• Please report any problems you encounter

ET seminar talk by Zach Etienne:
* wait for Zach to finish the code, then schedule a seminar at a
convenient date some weeks afterwards to leave enough time for announcements

Yours,
Roland
