It's not an acronym, it's the word "fat". On Linux x86 systems (either 32-bit or 64-bit), the MPIR binary is built with support for various kinds of processors. At run-time, the library checks the CPU it's running on and then decides which routines to run. So, if you're running a Sandy Bridge CPU, it will use Sandy Bridge instructions. On other systems (e.g. OS X or non-x86 Linux), there is no fat binary support but the binaries are built "generic", without assuming any particular CPU. So, the same binary should run on any CPU of a given architecture. -- To post to this group, send an email to sage-devel@googlegroups.com To unsubscribe from this group, send an email to sage-devel+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URL: http://www.sagemath.org
