permutes

This is in contrast to something like the the Fisher-Yates shuffle which permutes the elements in O(n) time.

Whenever it outputs a value, it further permutes the state by swapping some bytes of the state.

GPUs have a crossbar that allows for high speed lane-to-lane permutes and bpermutes, but it's still slow compared to butterfly shuffles.

The Update functions permutes the world and the Render function draws the new world.

For every 64 bytes, the avx512 version has one load&store and does two permutes, which Zen5 can do at 2 a cycle.

It's also slightly less optimal on x86, because it alway uses lane crossing permutes.

There are a lot of such instructions, including shuffles and permutes.

Rate of Congruence Coverage: - Ergodic Iteration: For a fixed prime $$ p $$, the map $$ n \mapsto 3n + 1 \mod p $$ permutes residues.

> the hardware detects which way it's plugged in and permutes the signals For USB3/4 signals, yes.

For example, check the simplest commutator LTL'T' and figure out how to use that as part of a larger commutator that permutes the three corners of a cube.

For example, less permutes/shuffles and more arithmetic instructions.

IMO the software ecosystem needs to steer the hardware here, in place of ARM for neon, and Intel/AMD for AVX, stopping people from implementations with disproportionately slow permutes.

Anything one does to “align” AI necessarily permutes the statistical space away from logic and reason, in favor of defending protected classes of problems and people.

It's called a "Sponge" because it splits hash into two distinct stages: one in which the hash function "absorbs" data, applying the hash core function to permute an internal state, and another in which the hash is "squeezed" to produce output (which further permutes the state).

And in fact USB-C is not really physically reversible, because the hardware detects which way it's plugged in and permutes the signals, as opposed to mirroring all the wires, so there is indeed a "right" way of inserting an USB-C plug, except it's impossible to tell which it is without a dedicated hardware tester.
