I just got a new machine with a Intel 1.3 P4 chip in it. I am aware that many (most) software companies have not optimized their code specifically for the chip. Furthermore, I have found that this machine is even slower, on many apps, than a 8xx P3 we have here. I enjoy using R and was wondering if there are any plans to create a version that accommodates this chip. -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)

Under what OS? AFAIK the only thing one can do is to find a compiler that optimizes for the P4, but I don't know of one, nor if it actually helps. As far as I am aware under both Linux and Windows the binary versions of R are not even optimized for an i686 (Pentium Pro/II/III), but I find that under Windows (and VC++) using the optimizations for i686 makes only negligible differences.
