Dear R-devel, A while ago Prof. Ripley had mentioned that g77 on AMD64 isn't the greatest, and the Salford Fortran is likely to be better. My question is, has anyone tried compiling R with Salford compilers (or other commercial compilers)? If so, do they offer performance advantages over GCC? TIA for any info.

compilers for R on AMD64

It's the Portland Group compilers which were recommended to us, and which we have been benchmarking as up to 50% faster than g77. http://www.pgroup.com/ If you (Andy) want to email hutchins@stats.ox.ac.uk she can put you in touch with our local expert.
