That may be reason enough to run a 64-bit kernel while keeping a 32-bit userland (libraries, applications, etc.) Which some (including myself) do. The advantage of 32-bit software is a smaller memory footprint (e.g. 32 bits to represent an integer instead of 64). There is a much wider software availability, and fewer compatibility issues. Although many say "64-bit is well established, no need to worry about compatibility", I've had a few run ins. At one point, I was maintaining two parallel Debian systems, one 32-bit and one 64-bit, to track down such issues. Some disadvantages to mixed systems, from the amd64 faq at http://alioth.debian.org/docman/view.php/30192/21/debian-amd64-howto.html Q: I want to run i386 userland with a 64bit Linux kernel A: Running 32bit userland with a 64bit kernel is recommended only for servers needing the absolute stability of 10 years of 32bit debian, but without the memory limitations the IA32 architecture bears, for example a 64bit mysql server on a system with 8GB or 16GB memory. Running the mixed setup on a workstation is not recommended, because iptables, the XFS filesystem, non-free NVidia and ATI binary drivers do currently not support it. Iptables *does* appear to work for me in mixed environment, at least the user interface part. Cheers, Joel -- Joel Roth

For those of you that undestand the following code, try to compile a program that has int x = new int; That will warn you about asigning 64bit pointer to a 32bit integer (if it doesn't warn you about asigning pointer to non-pointer variable). Another thing, I use 64bit Gentoo, and do my share of audio production (recording demos of my band, nothing fancy). I haven't found any 32bit app that I miss so far (now that flash is working again). Can you tell us which 32bit programs you need?

I'm pretty sure most all the important points on 64 vs 32bit have been covered by now, I just couldn't resist chucking in my 2p too whilst I wait for A3 to compile. The whole worry over 64bit has 'bled over' from the Windows world where it was a much bigger problem for them than for Linux users. Things have improved a lot for 64-bit Windows users as 64-bit Windows is much more prevalent than it was but finding drivers for 64-bit XP was tough as it never really took off like 64-bit W7 has. As has already been mentioned, benchmarks show AV encoding/decoding to be significantly faster under 64bit than running a 32bit OS on the same hardware and apparently the same is true for compilation. Someone has mentioned there being no 64-bit guitar pro build yet but it has already been mentioned in another thread on this list that GP requires Pulseaudio so that may put you off as it did for me. There is thankfully FOSS gtp file viewer called DGuitar although its obviously nowhere near as fully featured as GP6. I've been using the 64-bit 'square' flash plugin under buntu lucid x64 for the last week or so with no probs and I've also successfully used Lacies' Lightscribe label printing app under x64 (with an LG burner) without problem too. There really aren't too many other binary-only Linux apps out there, thank your lucky RMSs. This being a Linux Audio list I would say your main question is how badly do you want to run VSTs under Ardour as this isn't an option if you're running x64?
