About:
cpuid is a Go library that provides low-level CPU feature detection and identification. It allows Go applications to query the CPU's capabilities at runtime, enabling developers to optimize performance by selecting algorithms tailored to specific processor features like AVX2 or SSE4. This library is essential for building high-performance, hardware-aware Go software.

Key Features:

Runtime CPU feature detection (e.g., AVX, SSE, AES)
Access to CPU vendor, model, and family information
Cross-platform support for x86 and ARM architectures
Zero-dependency, pure Go implementation

Use Cases:

Optimizing cryptographic libraries by using hardware-accelerated instructions
Selecting the fastest math or data processing algorithm for the host CPU
Diagnostics and system information tools written in Go

Alternatives:

go-cpuid – Alternative library with similar goals, though cpuid is widely considered the standard for Go projects.
