While reading though the dsp code, I was wondering if the chunking for auto-vectorization is…

* I defined 2 function **Map_Center_Of_Mass_CPU** and **foo_noalias**, we can see the only different is that the function **foo_noalias** has extra **__restrict__** for the argument **int * crd**. Ac…

I tried kmeans fit_predict performance on 0.23-dev0 with mnist_all.csv dataset (http://ratml.org/datasets/mnist_all.csv). It seems elkan cost more time than lloyd (no matter dense or sparse format inp…

Chapel has the [`foreach`](https://chapel-lang.org/docs/technotes/foreach.html) construct to indicate a loop where the iterations are independent and may therefore be reordered or vectorized. However,…

A fundamental limitation of our auto diff tool JAX is it is [unable to handle dynamic size arrays](https://github.com/jax-ml/jax/discussions/18790) or jagged tensor operations. Both of these operation…

Two use cases:
1. More significantly, sometimes auto-vectorization with SIMD makes a function slower. There are the environment variables to disable auto-vectorization, but that affects _all_ code …

There are quite a few algorithms which can be vectorized, or one should at least look into doing so. This issue lists all the algorithms which I think can be vectorized (and a few that shouldn't be wi…

Auto-vectorization can improve performance for some loops. Because auto-vectorization reorders operations it violates strict IEEE floating point compliance so compilers require "fast math" options be …

I tried this code:
Compiler flags: `-C opt-level=3 -C target-feature=+avx2`
```rust
pub fn check(data: &[u8], lut: &[u8; 256]) -> bool {
let mut flag = 0;
for &x in data {
