The latest news is that (1) the weak-table fix in Guile¹ helps in
general but does not significantly reduce memory consumption when
compiling gnu/packages/python.scm (which requires ~1.5G on x86_64), and
(2) we’ve identified the compiler’s slot allocator as a major cause of
memory consumption and CPU cost when compiling large files like
python.scm:
https://lists.gnu.org/archive/html/guile-devel/2017-10/msg00035.html
Andy may work on a simpler slot allocator for -O0 and/or large functions
that doesn’t exhibit this pathological behavior.
In the meantime, our best workaround to reduce memory consumption is… to
split large files into smaller ones. Per M-x guix-locations, the
candidates are:
gnu/packages/python.scm 986
gnu/packages/perl.scm 401
gnu/packages/haskell.scm 348
gnu/packages/bioinformatics.scm 274
gnu/packages/statistics.scm 222
gnu/packages/emacs.scm 213
gnu/packages/xorg.scm 196
gnu/packages/web.scm 188
gnu/packages/gnome.scm 162
gnu/packages/ruby.scm 159
gnu/packages/java.scm 149
gnu/packages/ocaml.scm 126
gnu/packages/tex.scm 107
gnu/packages/linux.scm 106
I think we could focus on the first two or three files. FTR, compiling
bioinformatics.scm peaks at ~500 MiB resident on x86_64.
Ricardo, WDYT?
If we do this, do we split arbitrarily? Like the second half of
python.scm goes to python-cont.scm (provided there are no cross
top-level references)? Or do you have a better idea?
Ludo’.
