- Sounds familiar. If one of the authors Lemire? Of course.

- 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.

- This is just a worse copy of the original ifma method.
Sneller is even better for max throughput.
- Very impressive! But yeah AVX-512 is an awkward requirement.

- Our design exploits the AVX-512 instruction set
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.
