  Linear algebra foundation for the Rust programming language

the former is run with no parallelism, and the latter with `parallelism::Rayon(0)`, which presumably means that it has some parallelism, though I don't write rust or know what Rayon is.

• good_lp

  4 203 7.7 Rust

  Linear Programming for Rust, with a user-friendly API. This crate allows modeling LP problems, and lets you solve them with various solvers.

  

How exactly does this dovetail with https://github.com/rust-or/good_lp ? Will it be a replacement, an enhancement, or something else?

  1 20 - Rust

A bit of a tangent, but the same author has something like a libdivide (C++) for Rust: https://github.com/sarah-ek/fastdiv . Cool.

  BLAS-like Library Instantiation Software Framework

  

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.

  Python powered Fortran preprocessor

most of it's just general programming niceness. If you have to spend a few hours to wrestle with make/bazel/etc every time you need to reach for a dependency, you don't depend on things and have to rewrite them yourself. If your programming language doesn't have good ways of writing generic code, you either have to write the code once per precision (and do all your bugfixes/perf improvements in triplicate) or do very hacky metaprogramming where you use Python to generate your low level code (yes the Fortran people actually do this https://github.com/aradi/fypp), or use the C preprocesser which is even worse.
