I've been considering upgrading from 1 Gbps to 5 Gbps. Have you noticed any significant benefits for any particular use cases?

The author mentions Rust's portable SIMD library [0]. The only issue with portable SIMD is it's only available on nightly. I used it in my FFT crate, but we had to switch to the fearless_simd crate in order to get a portable SIMD

This argument usually depends on how you quantify defense spending, no? [0] In terms of PPP, the U.S. is falling behind. To be perfectly clear, that doesn't somehow absolve the size of U.S. defense spending. If anything, it's damn

I always remember it as the opposite of what I think is typically called the granny knot. In the case of the square knot, it's just right over left, then left over right.

Wow. I was not expecting that topic when I clicked on the link you provided. When I went through such a selection process years ago, we took all sorts of tests before and even after the selection process. Towards the end, the head instructo

The recently announced "Golden Dome" project intends to get around this issue by putting a vast constellation of satellites into orbit. Each satellite would likely need a serious source of power in order to use its laser. Assuming

That's also great for letting the compiler unlock auto-vectorization opportunities without delving into the world of manual SIMD. Even storing something simple such as an array of complex numbers as a structure of arrays (SoA) rather t

Hi, One of the authors of PhastFT here. Thank you for your interest. We went out of our way to configure FFTW for AVX-512. The Rust bindings don't do it, but the FFTW itself in the benchmark does. It's worth noting that with FFTW
