#SSE2

@aeva Currently the "dogshit wall" is #i486SX because #Linux dropped support for #i386 with Versions 3.4.99 & 3.6.9 respectably, tho most people would say anything below #amd64 w/ #SSE2 (or #i686) is out of #mainstream support already, with #RHEL6 being EoL'd & #Debian being the last major distros offering #32bit support.

Much discussion in my feeds around the rustc problem/bug generating bad code to do with SSE2;

lists.debian.org/debian-releas

Can't say I understand what is the root case there, but rust is not making friends in the vintage/retro computing world.

Nor the folks maintaining old kit for customers.

@cleantext well, it depends on what your productivity tool is.

  • 99% of my productivity is in #SSH so any #i486 "#shitbox" with #SSE2 acceleration is gonna be sufficiently fast (I could propably work from a #Pi0W with screen & keyboard attached.

It's also an exercise in #FrugalComputing and asking "What do I actually need to be able to work?" and the answer is pretty simple: An SSH-Terminal!

"A library that abstracts over SIMD instruction sets, including ones with differing widths. SIMDeez is designed to allow you to write a function one time and produce SSE2, SSE41, and AVX2 versions of the function."

#PaleMoon will be requiring #AVX support in CPUs for its official binaries starting from version 33.3.0, which can be expected to release on the second Tuesday of this August.

For those still stuck with #SSE2 you will either have to upgrade your processor to something more recent (AVX support has been commonly available for 10 years now) or switch to a community build that still builds support for SSE2.

EDIT: Oh and I forgot to mention too that this is only for 64-bit. 32-bit Windows binaries will still support SSE2 (there are not 32-bit only processors that supports AVX as far as I know anyway, and even if there are it would most likely result in worse performance due to how 32-bit x86 and AVX work)

#nibrans is a #publicdomain nibble based rANS coder.

nibrans is an #singleheader #SSE2 accelerated encoder and decoder for the rANS arithmetic coding format. rANS offers near-optimal data compression while having an adaptable frequency structure, unlike Huffman coding which uses a static structure. nibrans encode and decode data at a rate of up to 75-95 megabytes per second.
