Hmm, not that I'd be an expert...
If you want to use so much RAM you want to use a 64-bit
architecture and software (OS, libraries, compilers,...), right?
AFAIK, that's been known to work well with Opterons and different
flavors of Linuxen (e.g. we have dual
Opterons, one with Redhat Enterprise and two with Ubuntu 6.06).
Now I read that there are 64-bit Xeons with "EMT64" (which is
said to be Intel's emulation of AMD64), so in principle the same
versions of Linux and R should run there as well.
Since I haven't heard of any success stories
I'm interested as well, in reports from R users.
