That should be no problem on a 64 bit architecture. > I want to know if this is possible before spending 10,000 euros on a machine > that has 16 GB of memory. If you want to spend that amount of money on memory anyway, the extra cost for an AMD64 machine isn't that large. > The machine we plan to buy is a HP Proliant Xeon machine and I want to run a > 32 bit linux kernel on it (the xeon we want doesn't have the 64-bit stuff > yet) AFAIK you can't use a 15 GB tmpfs on i386 because large memory support is basically a hack to support multiple 4GB memory spaces (some VM guru correct me if I'm wrong). Just get an Athlon64 machine and run a 64 bit kernel on it. If compatibility is a problem, you can still run a 32 bit i386 userland on an x86_64 kernel.
