R devel - Jan 2016 - Possibly useful idea

I've not worked changing underlying computational infrastructure, but
developers who do might want to use ideas from FlexiBLAS. Apologies in
advance if this is well-known.

You have been able to do that at the OS level, given a suitable OS variant
like Debian, since the 1990s. My timing comparison package/vignette gcbd does
just that (adjusting before calling R).

I see nothing really new here. It's just dispatching. Sure, if your OS
allows
it you can roll it up into the OS. But not all OSs will so appeal to R is
limited.
