- TODO list for inhomog
* Add some mechanism for checking that required values in the
structures background_cosm_params and rza_integrand_params have
been initialised and are valid. [high priority; usability;
robustness]
* Documentation: doxygenisation. Rough initial draft done, as of
v0.1.1. [high priority; usability]
* Throwing errors - which suspicious choices should be considered
warnings vs fatal errors? which should be thrown up through
the hierarchy of routines using e.g. the <errno.h> library?
According to https://lintian.debian.org/tags/shlib-calls-exit.html,
*all* errors, including fatal ones, should be thrown up
the hierarchy and the C exit() function should not at all be
used. [medium priority]
* Libtool - in the extended regular expression of the libtool
option -export-symbols-regex in lib/Makefile.am, restrict
this to routines ("symbols") that really need to be used
externally; this will require increasing the V number of
the library, since this means removing symbols from the
interface. [low priority]
* Re-read IEEE and GNU guidelines and play with lib/test_gsl_ieee
to see if gsl ieee modes can be usefully integrated into inhomog.
[low priority]
- ---------- DONE -------------------------------------------------
* LCDM speed - try out Kasai (2010, arXiv:1012.2671) equation (5)
for the flat, non-EdS FLRW growth function: use maxima to obtain
polynomial+sqrt ratios for the first and second derivatives;
combine this with a_dot_flatFLRW to get the two time derivatives of
the growth function. Benchmark the Kasai vs Bildhauer et al
expressions; Kasai also refers to a less accurate Lahav
approximation used by Carroll. It's not clear if any of these
alternative expressions have less than about 20-30 operations
to compute, so the time invested might not improve the speed
by much. DONE: significant speedups - see notes in git, then in
ChangeLog or briefly in NEWS.
* LCDM speed - benchmark EdS vs LCDM calculation speed for
a call to Omega_D. Work out why LCDM seems to be about 80 or so
times slower than EdS and see if the LCDM case can be sped
up. FLRW_background.c has analytical formulae for the LCDM (generic
flatFLRW) a(t), t(a), and \dot{a}(t) functions, so the slowdown for
LCDM should not need to be so great. 2019-01-05: DONE: the non-EdS
growth function is the slowdown factor, by a factor of about
20-30.
* Debianisation - as of version >= 0.1.5 (debian: 0.1.5-1), inhomog
is available in source code at
https://anonscm.debian.org/cgit/debian-astro/packages/inhomog.git
or more generally, see
http://tracker.debian.org/inhomog for studying Debian warnings
and errors in the debianised version of inhomog; fixes should
preferably be done upstream at bitbucket so that they are available
for all users.
