The simplest SIMD practice: simd_memcpy() in C. It uses SIMD intrinsics and data types to copy memory 16bytes-by-16bytes, aka 128bits, not byte-by-byte. This is just a practice to have a glance at SIMD, which is a good facility provided by modern CPUs.

New record prime announced today. Here it is written in hexadecimal.
You asked for it, so here it is. Visualizing CPU cache speeds relative to RAM. Cache optimization is important too!
The wrong CPU scheduler can kill you. At one time, I used to work in aerospace. Most aircraft systems are separated into various levels of "criticality". Safety-critical systems are designed to lose <1 life per 10^9 hours of operation.
