Hi list,
I have been wondering if ATLAS should consider the Intel Atom N270 (and
the other members of the Atom family) Core2 cores for tuning purposes?
Currently they are not supported, so an ATLAS build takes 12 hours, but
adding them should be a three lines patch which I am more than happy to
do in case we agree it is a Core2 or something else that is already
supported :).
An overview over available models can be found at
http://en.wikipedia.org/wiki/List_of_Intel_Atom_microprocessorsand I tried to get more info from the Intel website, but I didn't seem
to find the right info (maybe being unfamiliar with their docs?)
Anyway, the CPU info reads from a N270:
