I am curious about two things:
1) I have to build ATLAS 3.8.2 on an Core i7 and as mentioned above
you have your own tuning setting in 3.9.6, so how much of a bad idea
would it be to use the Core2 tuning info for 3.8.2 for the i7 core?
Right now we get an unknown arch and have to do a full tune which is
kind of annoying if you build ATLAS more than once a week on that CPU.
I don't want to switch to ATLAS 3.9.6 yet in the Sage project, but I
don't think the switch will be too far into the future.
2) A while back I asked about how to treat the Atom (at least the 64
bit models with SSE3 and all that good stuff) and I did not recall
that anyone answered. Somebody else did ask me off list a couple days
about that, so it would be nice to get an answer. My instinct is to
make everything being treated as a Core2 for now.
