R Tools + OpenBlas / Intel MKL: Optional Feature

Open jtelleria opened this issue 6 years ago • 1 comments

Would it be possible to deliver an R Tools Version with an optional feature that enables compiling R with OpenBlas / Intel MKL?

Being optional it would allow to those concerned about accuracy in some applications to not use the Multi-threaded BLAS version, and use regular single-threaded BLAS instead.

Here are some Dirk Eddelbuettel articles which show how to compile R with Intel MKL on Ubuntu:

Thank you!

Best, Juan

This repository seems to have achieved this for OpenBLAS: https://github.com/thequackdaddy/R-OpenBLAS

However, I'm a bit nervous using it as my antivirus doesn't like his releases: https://github.com/thequackdaddy/R-OpenBLAS/issues/12

Even if it's legit, it would be nice to have an official/@jeroen build for peace of mind.
