Hello Jimmy:
MongoDB does run on Intel processors (both X86 and IA64 (also called Itanium)).
The HP-UX operating system can run on IA64 (Intel) or PA-RISC processors from HP. The HP PA-RISC processor is big-endian. As Dwight mentioned, the MongoDB server doesn't run on big-endian processors.
Therefore, if you want to run MongoDB on HP-UX on HP PA-RISC processor that will not be possible right now.
The HP-UX operating system doesn't run on X86:
The Intel IA64 processor can run in either big-endian or little-mode. However, it's not clear if HP-UX works on IA64 in little-endian mode. From these links it looks like HP-UX is big-endian only on IA64.
I don't know HP-UX very well and the links above are a bit old. I'd suggest you look at the machine you have and check if HP-UX is running big or little endian.
If your HP-UX machine is IA64 and running in little endian mode you could build MongoDB on the machine from source code.
SCons (
http://www.scons.org/) is a software build tool which is "designed from the ground up for cross-platform builds, and known to work on Linux, other POSIX systems (including AIX, *BSD systems, HP/UX, IRIX and Solaris), Windows NT, Mac OS X, and OS/2."
MongoDB can be built with SCons:
I hope this helps,
