I propose to make a synonym of and retag all questions.

Although is the bigger tag, it is not as unambiguous as which I would favour as master tag for that reason. The tag excerpts and wikis should be copied then of course.

Some stats about the two tags:

  • 18 questions
  • Excerpt:

    Running or compiling binaries made for CPU architectures different than the host system

  • Wiki: none

  • 86 questions
  • Excerpt:

    Architectures usually refer to the difference between 32-bit x86 (i386) and 64-bit x86-64 (amd64/em64t) processors. Both are distinct architectures.

  • Wiki:

    Architectures usually refer to the difference between x86 (i386) and x86-64 (amd64/em64t) processors. Both are distinct architectures. Use a tag specific to one architecture when a problem is believed to be architecture-specific.

    For example, if you're having a problem just with the amd64 live CD, and the i386 live CD worked fine, tag your question . Note that some architecture-specific problems are bugs (and Ask Ubuntu is not the place to report bugs, as detailed here).

    Ubuntu supports the following architectures:

    • amd64 (x64)
    • i386 (x86)
    • ARM
    • PPC/PowerPC (Old macs) -- This is unofficial.

    A processor that can run the amd64 architecture can run the i386 architecture also, as the processor is backward-compatible to a 16-bit architecture. Generally, most OSes start in 16-bit mode, then, very early, switch the CPU to i386, and optionally, amd64 mode.

    For questions about running 32-bit Ubuntu software on 64-bit Ubuntu systems, use the tag.

    The tag should not be used in the sense of design principles and decisions (unless, of course, they are also about computer architecture as described above). For such questions, please use the tag instead.

    Here is a merge needed too.
