This article includes an overview of different BLAS libraries along with benchmarks: http://cran.r-project.org/web/packages/gcbd/vignettes/gcbd.pdf It looks like using single-threaded ATLAS is already an improvement over LAPACK in most cases. I use Debian and it's straightforward to replace one with the other: you only have to install the libatlas3gf-base package and remove liblapack3gf and libblas3gf. Unfortunately, Debian does not include a multi-threaded version of ATLAS although they provide instructions on how to recompile the package yourself with multi-threading enabled. I don't know about SUSE, sorry. -- Bye, Ernest ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
