OpenBLAS in everyday R?
...the reference BLAS for reasons other
than speed.
For example, vecLib, Apple's multi-threaded BLAS library, is not the
default choice for macOS binaries due to concerns about 'precision'. See:

This doesn't appear to be Mac- or vecLib-specifc. R-Core seem wary of
non-reference BLAS implementations for several reasons:
'External BLAS implementations often make less use of extended-precision
floating-point registers and will almost certainly re-order computations.
This can result...

OpenBLAS in everyday R?
Hi R-devel list,
OpenBLAS is readily available for unix-likes:
https://cloud.r-project.org/web/packages/gcbd/vignettes/gcbd.pdf
However, my questions are:
1) Would R-devel consider using OpenBLAS for the main distribution of R for
all platforms including Windows?
2) If so, would R-devel set the default multi-thread level to the number of
(real) cores on a machine?
My sense is there're a
