I wonder if this can be categorized as galactic algorithm. I can't imagine systems where bulk of processing goes into integer to decimal string conversion but maybe there are such.
What will be the lifetime of AVX512? There have been many similar extensions before it. So it's a great result, but heavily marked by the target platform. I have the hope that RISC-V vector extensions will prove to be the more durable substrate to develop on, and a result there would be much more relevant for the future.
Decimal strings are for human consumption, I suppose. Not sure if the nanosecond timescale is relevant then (unless you send these numbers to billions of people which is unlikely). Sounds like a pointless exercise, or maybe they should have picked a better example.
AVX-512 is being discontinued in newer Intel consumer CPUs, particularly with the Alder Lake series, where it has been completely disabled through BIOS updates.
