why doesn't radfft support AVX on PC?

So there's two separate issues here: using instructions added in AVX and using 256-bit wide vectors. The former turns out to be much easier than the latter for our use case.

Problem number 1 was that you positively need to put AVX code in a separate file with different compiler settings (/arch:AVX for VC++, -mavx for GCC/Clang) that make all SSE code emitted also use VEX encoding, and at the time radfft was written there was no way in CDep to set compiler flags for just one file, just for the overall build.

[There's the GCC "target" annotations on individual funcs, which in principle fix this, but I ran into nasty problems with this for several compiler versions, and VC++ has no equivalent, so we're not currently using that and just sticking with different compilation units.]

The other issue is to do with CPU power management.

The case for deadlines

The case for deadlines

Rust aims to be the foundation of fast and robust software. A thorn in that side is the choice of timeout-centric APIs for I/O and multithreading. I posit this was a bad choice and it needs to be remedied as soon as possible before more APIs proliferate this (possibly accidental) design decision.

Motivating example: time limited network client request

Task: connect to a remote server, send a request, receive response with an end-to-end timeout of 10 seconds.
