Can one of you give me an R program that displays the benefits an accelerated BLAS in R?
I thought the standard benchmark was (the somewhat artificial) R-benchmark-25.R from http://r.research.att.com/benchmarks/R-benchmark-25.R . I have some examples using this to show the benefit of an external (optimized, multi-threaded) BLAS at http://www.cybaea.net/Blogs/Data/Faster-R-through-better-BLAS.html .
(But I have also seen R run slower with external BLAS, e.g. with Radford Neal's benchmarks in a recent post here on “Speeding up matrix multiplies”. YMMV.)
