Why? I ask as someone who supports R rpms on HPC systems and knows a
bit about relevant libraries and compilers.
Please visit this blog[0] or many other talking about R-benchmark.R.
If you want to subvert R's BLAS (and other slower versions) with
something largely optimal, look at the openblas-compat package under
<
https://copr.fedoraproject.org/coprs/loveshack/livhpc/>. [Yes, linear
algebra in Fedora is a shambles, with at least one failed attempt to
sort it out, but adding Intel stuff will only make things worse, and
that package finesses the issue fairly handily.]
I agree than open-blas is a good soultion, but not as fast as the
Intel BLAS libraries.
