I just bought a premier subscription/upgrade, and asked a sales representative some questions about this, because I'm toying with the idea of get a dual Opteron. I was told that the current release of Mathematica supports 64 bit on Linux, but is a "Class B" license (which is more expensive). In the next release (5.1, due out any day now), the 64-bit version will be reclassified as "Class A". The news release referred to below, which specifically addresses optimization for Linux on AMD 64, states that "Mathematica 5 is among the first technical computing platforms specifically optimized for the AMD64 architecture--and it delivers impressive performance. The optimized Mathematica port outperforms a regular Linux version of Mathematica on AMD64 systems by up to 50 percent in typical scientific and technical calculations...". I don't think the distro matters, except possibly for testing. Is that correct? Since I'm likely to get Fedora Core 3, I'll have to find out if Wolfram has tested it.

WRI advertise Mathematica 5 for AMD64, see: http://www.wolfram.com/news/amd64.html. I presume that this is the "Linux (64 bit optimized) " version . They have checked compatibility with SUSE Linux Enterprise Server 8 which supports 64 bit technology, hopefully this means that its OK on SUSE's desktop version; see http://www.suse.com/us/private/products/suse_linux/prof/64bit.html. So it looks as though a cheap 64 bit Mathematica is possible. Has anybody done it?
