Hi Ravi, Like Ista, I have also had success in using R with OpenBLAS on our Linux compute cluster. This will involve installing R from source. If you'd like, I can send you the configure settings I used, as well as the environment settings used to control OpenBLAS multithreading. The CRAN site also has some good documentation of this. Note that I had issues using the latest version of OpenBLAS (0.3.x) with R 3.5.1. I'm not sure if you would have the same issues as me, but to be safe I would suggest using OpenBLAS 0.2.x instead.
