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]]
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) 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. -roger Vadim Ogranovich wrote:> 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.

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) -- Brian D.

We've had good experience so far with the threaded Goto BLAS (on Opteron 244/248/250, SLES8). Has anyone tried building R with supposedly more optimized compilers (PGI, EKO, etc.)? If so, how do they stack up against GCC? Best, Andy> From: Roger D.

Thanks to everyone for the info. It is very valuable. I am a little bit uneasy about conflicting reports regarding RHEL 3, but I guess at this point I just need to try and see. It's also very soothing to know that there is an "official" 64-bit build on CRAN. Thanks again for taking time to answer, Vadim
