Insights Parallel Programming on a CPU with AVX-512

[Mark44]

This article is the second of a two-part series that presents two distinctly different approaches to parallel programming. In the two articles, I use different approaches to solve the same problem: finding the best-fitting line (or regression line) for a set of points.
The two different approaches to parallel programming presented in this and the preceding Insights article (Parallel Programming on an NVIDIA GPU | Physics Forums) use these technologies.

Single-instruction multiple-thread (SIMT) programming is provided on the Nvidia® family of graphics processing units (GPUs). In SIMT programming, a single instruction is executed simultaneously on hundreds of microprocessors on a graphics card.
Single-instruction multiple data (SIMD) as provided on x64 processors from Intel® and AMD® (this article). In SIMD programming, a single instruction operates on wide registers that can contain vectors...

That's an interesting, and surprising, result. Most people seem to have assumed the opposite. Thank you for this work!
