Top 23 C++ Concurrency Projects

  • Swoole

    šŸš€ Coroutine-based concurrency library for PHP

  • Project mention: Performance benchmark of PHP runtimes | dev.to | 2024-01-17

    Swoole

  • Taskflow

    A General-purpose Parallel and Heterogeneous Task Programming System

  • Project mention: Improvements of Clojure in his time | /r/Clojure | 2023-06-16

    For parallel programming nowadays, personally I reach for C++ Taskflow when I really care about performance, or a mix of core.async and running multiple load balanced instances when Iā€™m doing more traditional web backend stuff in Clojure.

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.

  • ZeroMQ

    ZeroMQ core engine in C++, implements ZMTP/3.1

  • Project mention: Lightweight and fast AMQP (0-9-1) server | news.ycombinator.com | 2024-04-07

    Slightly OT:

    Are ZeroMQ and NanoMQ still widely used (and recommended)?

  • moodycamel

    A fast multi-producer, multi-consumer lock-free concurrent queue for C++11

  • ArrayFire

    ArrayFire: a general purpose GPU library.

  • readerwriterqueue

    A fast single-producer, single-consumer lock-free queue for C++

  • C++ Actor Framework

    An Open Source Implementation of the Actor Model in C++

  • NCCL

    Optimized primitives for collective multi-GPU communication

  • Project mention: MPI jobs to test | /r/HPC | 2023-06-06

    % rm -rf /tmp/nccl ; git clone --recursive https://github.com/NVIDIA/nccl.git ; cd nccl ; git grep MPI Cloning into 'nccl'... remote: Enumerating objects: 2769, done. remote: Counting objects: 100% (336/336), done. remote: Compressing objects: 100% (140/140), done. remote: Total 2769 (delta 201), reused 287 (delta 196), pack-reused 2433 Receiving objects: 100% (2769/2769), 3.04 MiB | 3.37 MiB/s, done. Resolving deltas: 100% (1820/1820), done. README.md:NCCL (pronounced "Nickel") is a stand-alone library of standard communication routines for GPUs, implementing all-reduce, all-gather, reduce, broadcast, reduce-scatter, as well as any send/receive based communication pattern. It has been optimized to achieve high bandwidth on platforms using PCIe, NVLink, NVswitch, as well as networking using InfiniBand Verbs or TCP/IP sockets. NCCL supports an arbitrary number of GPUs installed in a single node or across multiple nodes, and can be used in either single- or multi-process (e.g., MPI) applications. src/collectives/broadcast.cc:/* Deprecated original "in place" function, similar to MPI */

  • libcds

    A C++ library of Concurrent Data Structures

  • HPX

    The C++ Standard Library for Parallelism and Concurrency

  • Project mention: Does anyone know any good open source project to optimize? | /r/cpp | 2023-06-07
  • parallel-hashmap

    A family of header-only, very fast and memory-friendly hashmap and btree containers.

  • Project mention: The One Billion Row Challenge in CUDA: from 17 minutes to 17 seconds | news.ycombinator.com | 2024-04-13

    Standard library maps/unordered_maps are themselves notoriously slow anyway. A sparse_hash_map from abseil or parallel-hashmaps[1] would be better.

  • concurrencpp

    Modern concurrency for C++. Tasks, executors, timers and C++20 coroutines to rule them all

  • Project mention: Is anyone using coroutines seriously? | /r/cpp | 2023-12-05

    I am using concurrencpp for my project. What I like about it is that it's basically a thread pool factory with coroutines. It allows for better structuring / organizing of multithreaded work. So for me the main advantage of coroutines is that the code looks easier to follow

  • thread-pool

    BS::thread_pool: a fast, lightweight, and easy-to-use C++17 thread pool library

  • moderngpu

    Patterns and behaviors for GPU computing

  • Boost.Compute

    A C++ GPU Computing Library for OpenCL

  • junction

    Concurrent data structures in C++

  • CacheLib

    Pluggable in-process caching engine to build and scale high performance services

  • MPMCQueue.h

    A bounded multi-producer multi-consumer concurrent queue written in C++11

  • stdgpu

    stdgpu: Efficient STL-like Data Structures on the GPU

  • C++React

    C++React: A reactive programming library for C++11.

  • RaftLib

    The RaftLib C++ library, streaming/dataflow concurrency via C++ iostream-like operators

  • SPSCQueue.h

    A bounded single-producer single-consumer wait-free and lock-free queue written in C++11

  • continuable

    C++14 asynchronous allocation aware futures (supporting then, exception handling, coroutines and connections)
