Ho, ho. I've been told by a NAG representative that we should pay them to talk to our own academics who actually do the serious linear algebra! Also I was told they were contracted to do the old AMD proprietary BLAS, which was inferior to OpenBLAS, and has been dropped in favour of BLIS. I don't wish to slight the general quality of their stuff, though. Their Fortran compiler is notable in this context.
You don't get the large scale parallel libraries from NAG anyway.

do 'we'?
considering a huge amount of common numerical software (esp with any kind of fortran lineage whatsoever) is based in some way on netlib.org code that itself was heavily developed in the BSD UNIX on Vax+ARPANET era within the academic/research community, I'm not really sure that, based on this comment, 'we' do..
