A C99+ library providing concurrency primitives, safe memory reclamation mechanisms, and non-blocking data structures for high-performance concurrent systems.
Concurrency Kit is a C library that provides a comprehensive suite of concurrency primitives, safe memory reclamation mechanisms, and non-blocking data structures. It is designed to aid in the research, design, and implementation of high-performance concurrent systems, offering architecture-optimized components for building scalable applications.
Systems programmers, researchers, and developers working on high-performance concurrent applications in C, particularly those implementing custom lock-free data structures or requiring fine-grained synchronization primitives.
Developers choose Concurrency Kit for its extensive collection of battle-tested, architecture-specific implementations, its focus on both performance and correctness, and its role as a reference for state-of-the-art concurrency algorithms—all in a portable C99+ library.
Concurrency primitives, safe memory reclamation mechanisms and non-blocking (including lock-free) data structures designed to aid in the research, design and implementation of high performance concurrent systems developed in C99+.
Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Provides specialized assembly code for multiple CPU architectures like x86, ARM, and PPC, with fallbacks for portability, ensuring peak performance as noted in the supported architectures list.
Includes a wide array of lock-free data structures such as FIFOs, stacks, queues, and hash sets with various concurrency specializations, detailed in the README's data structures section.
Offers battle-tested mechanisms like epoch-based reclamation and hazard pointers, essential for correct lock-free memory management in high-performance systems.
Features numerous lock implementations, barriers, and NUMA-aware locks like cohort locks, providing tools for fine-grained synchronization, as highlighted in the synchronization primitives section.
Requires manual compilation and installation via configure and make, which is more cumbersome than package-manager-based libraries, and the README offers minimal guidance beyond basic steps.
The README is brief and lacks detailed usage examples or API references, forcing users to rely on source code or external resources for practical implementation.
Assumes deep knowledge of memory models, concurrency patterns, and C programming, making it inaccessible for developers without systems programming experience.
