Just for completeness, here are the MacPro timings using the R-devel nightly from Simon's website. Hilbert is slower than with my version of R-devel, and loess is faster (though still slower than on the G5).

This gives timer.R, as well as results for -- a quad G5 with 4GB RAM and R-devel compiled with vecLib and gcc-3.x-- a quad MacPro with 5GB RAM and R-devel compiled with vecLib and gcc-4.2.0You'll see the MacPro/G5 time ratio is about 0.60, almost twiceas fast, for the hilbert and sort tasks. For loess the MacPro is slower (!!), but that probably is a function of the two different versions of vecLib.I'll try the Intel compilers and the appropriate ATLAS (or Intel MKL/IPPframeworks) later. <timings_MP.R> <timings_G5.R> <timer.R> ===Jan de Leeuw; Distinguished Professor and Chair, UCLA Department of Statistics; Editor: Journal of Multivariate Analysis, Journal of Statistical Software US mail: 8125 Math Sciences Bldg, Box 951554, Los Angeles, CA 90095-1554 phone (310)-825-9550; fax (310)-206-5658; email: [EMAIL PROTECTED].mac: jdeleeuw ++++++ aim: deleeuwjan ++++++ skype: j_deleeuw homepages: http://gifi.stat.ucla.edu ++++++ http://www.cuddyvalley.org---------------------------------------------------------------------- ---------------------------No matter where you go, there you are. --- Buckaroo Banzai http://gifi.stat.ucla.edu/sounds/nomatter.au---------------------------------------------------------------------- ---------------------------
