Robert Bradshaw did a list of what he considered the most important
parts of Sage, and includes BLAS in that. I have just checked and see
there is no self-test package for BLAS.
So I'm wondering if we need BLAS or not.
Me too. FWIW, that was one of them that I was unsure of, but figured
better safe than sorry and assumed it was used somewhere in the linear
algebra, so I put it on the important list.
I suspect it is currently used, but perhaps we can remove it. That will probably
mean changing a few packages which currently link with BLAS, to force them to
link with ATLAS instead. Unfortunately, many of the packages which link to blas
have lots of platform specific code, so things behaving differently on different
platforms. Testing that sort of thing becomes difficult when you don't have
access to all the platforms.
I'm glad 'ghmm' has gone from 4.4.4.rc0. That looked like it was going to be
difficult to build on OpenSolaris,
Dave
