This could be a replacement for Atlas (these blas are supposed to be
faster).
t.d.
How active is the project? The second sentence in the above page is:
"This product is no longer under active development by TACC, but it is
being made available to the community to use, study, and extend."
Thanks,

According to the developer's wikipedia page [1], Kazushige Gotō joined
Microsoft's Technical Computing Group in 2010. I wonder if that's why
the library appears to be abandoned to the open source community.
Thanks,

According to a colleague of mine; there is a ticket to include the Goto
blas in a forthcoming Debian distribution. And according to many friends
doing numerics, these blas are faster than atlas blas.
But may be the question, for Sage, is: how long does it takes to install
Goto blas, compared to atlas ?
t.d.
.....
It is active, but there is now a gotoblas2 which is active as far as I
know:
http://www.tacc.utexas.edu/tacc-projects/#blas
From memory gotoBlas (version 1) was compiling faster on my old machine
than the latest atlas. We had to remove gotoblas-1 source from the gentoo
tree because TACC didn't want us to redistribute them anymore.
The next thing to check is whether it provides both cblas and f77blas.
Version 1 only provided f77blas and we need cblas as well.

So it isn't actively developed by the TACC
anymore, it is given to the community to
maintain and take over development.
It only provides f77blas. I guess it would
be possible to create a cblas interface using
f2c but it is not really something anyone would
want to maintain.
So unless someone can suggest an alternative
cblas implementation as well, gotoblas is not
a viable alternative.
The LAPACK it downloaded also seems to be BSD licensed. It's written
in Fortran I believe.
The documentation says you can customise the build process in various
ways.
.....
Lapack is indeed Fortran, there are two CLapack implementation floating around
one produced by ATLAS and an f2c version of the netlib reference fortran implementation.
