R help - Jul 2013 - Installing OpenBLAS in R

Hello again,

I was wondering if it is possible to install OpenBLAS linear algebra
library in R running under windows.

I found some study saying working with OpenBLAS would significantly
speed-up the calculations in R.

Thanks for your pointer.

Thanks and regards,

You will have to re-compile R from source and re-install it.

http://cran.r-project.org/doc/manuals/r-devel/R-admin.html

and in particular

http://cran.r-project.org/doc/manuals/r-devel/R-admin.html#BLAS

For what it's worth, on my Core i5 processor running linux I found
that ATLAS BLAS is somewhat faster than OpenBLAS.

HTH,

Peter
