For distributed scenarios where the architecture, language and library are unspecified and effectively random, it is not. Not so long ago x87 80-bit precision was common while non x87 systems typically used single and…
This is just aggressive loop unrolling. Duff's device is specifically the syntactic curiosity in C/C++ that allows implementing unrolls with a switch and inner while statement.
