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.

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.

Brian, Thanks for the note and apology for the misquote. I should probably see if there's anything I can do to help the Alzheimer's program here...
