Comment(by leif):
P.S.: This would perhaps even allow specifying cache sizes manually,
though the proper way would be something like
{{{
#!sh
$ export M4RI_EXTRA_OPTS="--L1-cache-size=32 --L2-cache-size=1024" #
passed to M4RI[E]'s 'configure'
$ sage -i m4rie
}}}
(And similar options for other cache parameters like the cache line
sizes.)
Specifying these may at least ''speed up'' the tuning (by omitting a lot
of tries); don't know if you could skip tuning, given these, in whole.
Storing and using tuning parameters analoguous to GMP's `gmp-mparams.h`
(including defaults for a couple of platforms / processors) wouldn't be
bad either; then [optionally] bypassing self-tuning would really make
sense.
[Disclaimer: Haven't looked at the spkg at all, so there might be better
or other ways to achieve this.]
