Not that I'm aware of, unless you mean something like
/sys/src/libmp/386/mpvecdigmuladd.s.
In my own "Beowulf-type applications" (domain decomposition for solving
partial differential equations) the 64-bit arithmetic was floating point.
64-bit fixed point seems more relevant to large SMP systems than to clusters.
