Lock Free Spsc Ring Buffer, . In this demonstration, I just "let it hang". Avoid cache thrashing of shared head/tail. The example doesn’t check the return value of push() because exactly 100 numbers are added to the queue. Also, you would probably make the producer in charge of freeing the shared memory segment in due time. Buffer Management That Saved Our Physics System Our circular buffer implementation reduced physics event drops from 18/second to zero in UE5 Chaos tests: Pre-allocate 2x peak memory (we use 8MB buffers) Implement lock-free SPSC queues Add heartbeat monitoring every 50ms Pro Tip: We caught 83% of buffer issues by adding this simple Unity Lock-Free SPSC Ring Buffer. hpp) - Lock-free SPSC ring buffer with power-of-2 sizing for optimal performance. Because boost::lockfree::spsc_queue is implemented with a circular buffer, the queue in Example 46. A collection of lock-free data structures written in standard C++11 - DNedic/lockfree Aug 29, 2025 · I'm excited to share a deep-dive into my latest project: a lock-free ring buffer implemented in modern C++17, designed specifically for the ultra-low latency demands of high-frequency trading and real-time financial systems. - avhz/ringbuffer ⚡ Features 🔄 Lock-Free Ring Buffers SPSC - Single Producer Single Consumer (~5ns latency) MPSC - Multi Producer Single Consumer MPMC - Multi Producer Multi Consumer Cache-line aligned to prevent false sharing Power-of-2 sizing for branchless modulo Bulk operations for batching See `tests/` directory for C client FFI compatibility tests. I'm hoping that the focus can be of the correctness of the atomic operatio Nov 8, 2025 · This lock-free ring buffer idea is not just theory — it powers real ultra‑low‑latency systems. Its aim is to be as simple as possible, while being correct. Producer is used to insert items to the ring buffer, consumer - to remove items from it. Jun 10, 2025 · A compact, header-only single-producer / single-consumer (SPSC) ring buffer for lock-free communication between exactly one writer thread and one reader thread. + +## Implementation Status + +### Implemented + +- Connection handshake (SOCK_STREAM setup socket) +- Authentication via SO_PASSCRED (uid/gid/pid) +- QB_IPC_SHM transport (shared memory ring buffers) +- Lock-free SPSC ring buffers +- Async I/O via tokio +- Abstract Unix sockets for The following binary packages are built from this source package: librust-ringbuf-dev Lock-free SPSC FIFO ring buffer with direct access to inner data - Rust source code Producer-Consumer Ring Buffers This project implements several variations of single-producer, single-consumer (SPSC) ring buffers in C++17, progressing from a simple mutex-based implementation to a high-performance lock-free version. Write requests that cannot fit in an available contiguous area will wait till space is newly available (after the consumer has read the data). 2 days ago · 1. 9 timings for tiny call sites.
