Top 9 C++ parallel-programming Projects

  • codon

    A high-performance, zero-overhead, extensible Python compiler using LLVM

    • Project mention: Should I Open Source my Company? | news.ycombinator.com | 2024-01-22

    https://github.com/exaloop/codon/blob/develop/LICENSE

    Here are some others: https://github.com/search?q=%22Business+Source+License%22+%2...

  • 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 I’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.

  • 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.

  • cccl

    CUDA C++ Core Libraries

    • Project mention: GDlog: A GPU-Accelerated Deductive Engine | news.ycombinator.com | 2023-12-03

    https://github.com/topics/datalog?l=rust ... Cozo, Crepe

    Crepe: https://github.com/ekzhang/crepe :

    > Crepe is a library that allows you to write declarative logic programs in Rust, with a Datalog-like syntax. It provides a procedural macro that generates efficient, safe code and interoperates seamlessly with Rust programs.

    Looks like there's not yet a Python grammar for the treeedb tree-sitter: https://github.com/langston-barrett/treeedb :

    > Generate Soufflé Datalog types, relations, and facts that represent ASTs from a variety of programming languages.

    Looks like roxi supports n3, which adds `=>` "implies" to the Turtle lightweight RDF representation: https://github.com/pbonte/roxi

    FWIW rdflib/owl-rl: https://owl-rl.readthedocs.io/en/latest/owlrl.html :

    > simple forward chaining rules are used to extend (recursively) the incoming graph with all triples that the rule sets permit (ie, the “deductive closure” of the graph is computed).

    ForwardChainingStore and BackwardChainingStore implementations w/ rdflib in Python: https://github.com/RDFLib/FuXi/issues/15

    Fast CUDA hashmaps

    Gdlog is built on CuCollections.

    GPU HashMap libs to benchmark: Warpcore, CuCollections,

    https://github.com/NVIDIA/cuCollections

    https://github.com/NVIDIA/cccl

    https://github.com/sleeepyjack/warpcore

    /? Rocm HashMap

    DeMoriarty/DOKsparse:

  • oneMKL

    oneAPI Math Kernel Library (oneMKL) Interfaces

  • grab

    experimental and very fast implementation of a grep (by stealth)

    • Project mention: Ugrep – a more powerful, ultra fast, user-friendly, compatible grep | news.ycombinator.com | 2023-12-30

    Also look at https://github.com/stealth/grab from Sebastian Krahmer.

  • CPURasterizer

    CPU Based Rasterizer Engine

  • librapid

    A highly optimised C++ library for mathematical applications and neural networks.

    • Project mention: Huge LibRapid Update -- New Features, Performance Improvements and Bug Fixes | /r/cpp | 2023-08-04

    In addition to all of these changes, I used LibRapid and Surge to write a simple Flappy Bird genetic AI as a proof of concept. The code runs well on all platforms and can simulate over 20,000 birds without too much trouble. If you want to check it out, here's the GitHub page: https://github.com/Pencilcaseman/FlappyBirdAI

  • LLVM-Guide

    LLVM (Low Level Virtual Machine) Guide. Learn all about the compiler infrastructure, which is designed for compile-time, link-time, run-time, and "idle-time" optimization of programs. Originally implemented for C/C++ , though, has a variety of front-ends, including Java, Python, etc.

NOTE: The open source projects on this list are ordered by number of github stars. The number of mentions indicates repo mentiontions in the last 12 Months or since we started tracking (Dec 2020).
