ROFL, with `SAGE_ATLAS_ARCH="AMD64K10h,SSE3,SSE2,SSE1,3DNow"` (which
involves self-tuning) it took
{{{
real 36m15.153s
user 31m23.290s
sys 5m56.960s
Successfully installed atlas-3.10.0
}}}
Also a bit strange is that the timing for `ptestlong` (all for Sage
5.2.rc0, GCC 4.4.3) was
`base` < `fast` < `AMD64K10h`
(i.e., fastest with `SAGE_ATLAS_ARCH=base`), although I think at least
during the last run the machine was partially loaded with other stuff as
well, and clearly `ptestlong` isn't very appropriate to benchmark ATLAS
performance... ;-)
[Not going to use the ATLAS tools for comparison right now, perhaps
later...]
