Hi,
We are planning to buy a 64-bit Linux machine which will mainly run R. There was an interesting thread on 64-bits on r-help back in April that basically confirmed that the 64-bit R is fine as long as the length of an atomic object is less than 2^31 - 1.
That's an R limitation, not a 64-bit version one.
My specific question is on which 64-bit Linux distros (SUSE or RedHat) and processors R is *known* to build out-of-box and run well. Ease of maintenance is essential here. We have RedHat 7.3 on other (32-bit) machines and would try not to proliferate the OS-s.
Not RHEL 3: we sent that back for a refund and its compilers are too old to work well on AMD64. Fedora Core 3 is fine on AMD64, and is what I would recommend. We also run SuSe 9.1, but for people used to RH, Fedora is more familiar.
CRAN will have 64-bit RPMs for x86_64 FC3 come R 2.0.1 (released on Monday)
