Ultimate Linux Box (was RE: [R] optimal windows R machine)
Well, maybe this is sort of related... Eric Raymond has written an article for the Linux Journal on how to build an Ultimate Linux Box. You can find the whole thing at http://www2.linuxjournal.com/cgi-bin/frames.pl/articles/style/0014.html The machine is said to compile the Linux 2.4.9 kernel in 1 min. 50 sec. I wonder how long it might take to build R on this beast...

I > wonder how long it might take to build R on this beast...My guess is that it's about twice as fast as this beast (2xPentiumIII,866): [Current R-devel] 291.64user 13.57system 4:01.62elapsed 126%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (586156major+348522minor)pagefaults 0swaps The R builds spend quite a lot of time building the documentation, and are locked to uniprocessor mode for the duration. This is because it runs as a single perl script that processes all .Rd files in a package. There's a good reason for that, but splitting things across a couple of perl runs would speed things up considerably. The compile part can be done (setting MAKE="make -j5") in 165.89user 12.78system 1:46.26elapsed 168%CPU (0avgtext+0avgdata 0maxresident)k 0inputs+0outputs (634972major+360981minor)pagefaults 48swaps (This machine is still running RedHat 6.2 with it's default dodgy compiler, so make check doesn't run...) -- O__ ---- Peter Dalgaard Blegdamsvej 3 c/ /'_ --- Dept. of Biostatistics 2200 Cph.

[R] Updated tutorial [R / Epid] - Problem with .PDF file in archive
All, A handful of users have reported problems extracting the PDF file from the ZIP archive (Rex1031.zip). I don't know what caused the problem so I have recreated the archive and posted it to my website: http://www.myatt.demon.co.uk This morning (19 Oct 2001). I hope that this solves the problem. It may take some time for the file to migrate to the public facing servers ... better to wait a day before retrieving the new file (dated 19 Oct 2001). Thanks to all of you who reported the problems and sorry for any inconvenience caused. Best wishes, Mark -- Mark Myatt -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help 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 !)
