memory-ordering

atomics and memory ordering related stuff

Lock-free queues in Rust: SPSC ring, bounded MPMC and unbounded Michael-Scott with hazard pointers. Orderings explained and checked with loom, ABA demo, benchmarks.

Wait-free single-producer single-consumer ring buffer in C++20. Cache-line padded, index-caching, TSan-verified memory ordering, and a benchmark that refuses to publish ratios it cannot trust.

Zero-copy IPC between Linux processes. Lock-free SPSC ring buffer over POSIX shared memory - 8.6 GB/s, 14.5 KB binary, zero dependencies.

Zero-dependency high-performance synchronization library for Linux x86-64

Pthreads litmus tests for hardware memory ordering — SB/MP/SPSC/Peterson on x86 TSO and ARM RMO: observe the reordering, fix it with barriers.
