About:
ConcurrencyKit provides a robust suite of highly optimized primitives for building concurrent and parallel systems in C. It offers lock-free data structures, atomic operations, and hash functions designed to maximize performance on modern hardware. The library helps developers avoid common concurrency pitfalls while ensuring portability across different architectures.

Key Features:

Lock-free data structures (arrays, hash tables, stacks)
High-performance atomic operations and memory barriers
Efficient hash functions and RNG utilities
Cross-platform support (x86, ARM, PowerPC, etc.)
Minimal dependencies and cache-conscious design

Use Cases:

Building high-performance multithreaded servers and applications
Implementing custom memory allocators and synchronization primitives
Optimizing low-level data structures for parallel processing

Alternatives:

Intel TBB – TBB provides higher-level parallel algorithms, while ConcurrencyKit focuses on low-level primitives and lock-free data structures.
libatomic – libatomic offers standard atomic operations, whereas ConcurrencyKit includes additional data structures and optimized utilities.
