Hotspot has support for [auto-vectorization](https://cr.openjdk.java.net/~vlivanov/talks/2017_Vectorization_in_HotSpot_JVM.pdf). That is, the jvm will identify certain looping patterns on arrays and g…

I tried this code:
```rust
pub fn count_non_ascii(buffer: &[u8]) -> u64 {
let mut count = 0;
for &b in buffer {
if b >= 0x80 {
count += 1;
}
}
co…

Thanks for developing SIMD.jl which I use in a number-crunching project of mine for explicit vectorization.
When experimenting with SIMD I realized that many math functions (e.g. exp, log), when gi…

**Describe the solution you'd like**
IEEE Superscalar SIMD architecture / loop parallelism or vectorization in code here can significantly speed up FP calculations, depending on the levels of floatin…

There are 8 np loops in limiter_optim_iter_full subroutine in prim_advection_mod.F90. In most cases, np is 4 and most of the loops have trip counts of 4-by-4, 4, or 16. Since the call to this subrouti…

@Dandandan raised the idea of considering the `slipstream` crate for SIMD / auto-vectorization.
I agree that we should consider it - if anything, to offload that part of the code-base to `slipstre…

I've been working with some other database things recently and it seems that Rust compiler cannot automatically vectorize array-array operation.

As discussed here:
https://github.com/rust-lang/rust/issues/21690
`-ffast-math` can be very useful to speedup floating point operations, particularly allowing easier vectorization. I'm seeing a …
