R on 64-bit Linux machine

I've built (and routinely use) 64 bit R on the following platforms: Red Hat Enterprise Linux AS release 3 (AMD Opteron 848) Fedora Core 2 x86_64 (AMD Athlon 64 3800+) SuSE SLES 8 (AMD Opteron 248)
Nice to know about the Enterprise variants. FC2/3 and SUSE 9.1 are known good too (did anyone check 9.2 yet?).
One problem that has come up is that if you want to link R with ATLAS, you need to build shared ATLAS libraries (rather than static). This requires some modifications to the configuation files for ATLAS. But my experience shows that R itself builds out of the box on these systems.
Actually, you can just go through configuration and add -fPIC to the compiler flags. Then at the end, run ld --shared --whole-archive -o libatlas.so libatlas.a etc. [If you don't accept architectural defaults (as you probably shouldn't), the compile/optimize is going to take a while. I wouldn't know how big the difference is, but -fPIC _will_ force code differences.]

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. 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. Your information will be highly appreciated, Thanks, Vadim [[alternative HTML version deleted]]
