BLAS-like Library Instantiation Software Framework

Project mention: Faer-rs: Linear algebra foundation for the Rust programming language | news.ycombinator.com | 2024-04-24

BLIS is an interesting new direction in that regard: https://github.com/flame/blis
>The BLAS-like Library Instantiation Software (BLIS) framework is a new infrastructure for rapidly instantiating Basic Linear Algebra Subprograms (BLAS) functionality. Its fundamental innovation is that virtually all computation within level-2 (matrix-vector) and level-3 (matrix-matrix) BLAS operations can be expressed and optimized in terms of very simple kernels.

osqp

4 1,559 6.1 C

The Operator Splitting QP Solver

Project mention: Best/Any Convex Optimization Solver for Rust? | /r/rust | 2023-05-31

There's also two bindings for the osqp library (which is written in C), osqp published 2 years ago and osqp-rust published 3 months ago. I don't know what are the differences between them, but they both target osqp 0.6.2 (released in 2021) while the last released version is osqp 0.6.3 which was released last week.

acados

5 674 8.7 C

Fast and embedded solvers for nonlinear optimal control
libfirm

2 451 5.2 C

graph based intermediate representation and backend for optimising compilers
FastDoom

18 345 9.6 C

Doom port for DOS, optimized to be as fast as possible!

Project mention: Doom(1993) on SSD1306 | /r/arduino | 2023-06-24

I'm 4 days late, but no, Doom won't run on an ESP32. The problem is RAM: original Doom requires 8 MiB. There's a port, FastDoom, that has been trimmed down to run on lower end computers, but even it requires 4 MiB. ESP32s typically have less than 512 KiB RAM.
