compiling R with tuned BLAS
Which OS are you using (Windows, Linux (distro), Mac)? When you mention .so files I tend to assume you are using a Linux system. If you are using ubuntu, changing the BLAS used by R is relatively trivial by using 'update-alternatives'. More detail is provided at the following link: http://www.stat.cmu.edu/~nmv/2013/07/09/for-faster-r-use-openblas-instead-better-than-atlas-trivial-to-switch-to-on-ubuntu/ Charles

I am looking at the instructions on http://cran.r-project.org/doc/manuals/r-patched/R-admin.html#ATLAS I have noticed that ATLAS produces two shared libs in addition to the *.a files: http://math-atlas.sourceforge.net/atlas_install/node22.html contents of the ATLAS lib directory: libatlas.a libcblas.a libf77blas.a liblapack.a libptcblas.a libptf77blas.a libsatlas.so libtatlas.so The instructions do not appear to match up with the *.a files & *.so files as described. (it appears to want me to use shared libs, but the names defined are static libs, not shared libs). should I simply be having it link against libtatlas.so (and pthreads) for shared threaded atlas and libsatlas.so for shared sequential atlas? do I need shared versions of the other static libraries? I think the help is a bit out of date, or at least unclear as to what it intends of me. M. Gooch
