SIMD getting started

SIMD (Single Instruction, Multiple Data), in simple terms, refers to CPU instructions that allow computations to take place in parallel. While standard instructions typically execute one at a time (scalar), SIMD performs multiple calculations simultaneously. For example, you can process 8 data points in a single clock cycle, significantly optimizing both performance and power efficiency.

This post focuses on NEON (ARM's SIMD architecture) rather than Rust's standard SIMD library, simply because I prefer the control of specialization over generalization.

Hot reloading

Hot reloading is an effective way to keep development iterations fast. Furthermore, it could—and probably already does—help solve some production issues. Here, we will take a naive and simplified look at how it could be used for a live trader to reload a critical component without restarting the entire suite, but instead only a specific component.
