I see. Even then, to outperform, say, ATLAS, Intel's MKL, or nVidia's
CUBLAS, is extremely challenging. I think this will already hold for a
serialized execution model. On top of that, when taking into account that a
BLAS (or LAPACK for that matter) can be replaced by parallel and/or
distributed execution models (threaded/PBLAS/ScalaPACK) I would say it's
near impossible.

Besides, what is nicer to be able to plug-in a new GPU and to be quickly
able to use its power to full extend? Or, given the dominance and vendor
support of the BLAS API, some other future piece of hardware?
