Top 20 C++ parallel-computing Projects

  • Taskflow

    A General-purpose Parallel and Heterogeneous Task Programming System

    Project mention: gcl v1.1 released - Graph Concurrent Library for C++ | reddit.com/r/cpp | 2023-01-27

    Cool. Thanks! How does it compare to taskflow?

  • Vc

    SIMD Vector Classes for C++

    Project mention: The Bitter Truth: Python 3.11 vs Cython vs C++ Performance for Simulations | reddit.com/r/cpp | 2022-12-30

    Most high-performance math libraries perform a lot of vectorization (Eigen, etc) under the hood. And you've got stuff like Klein, Vc (which is reminiscent of std::valarray), etc. Then there's OpenMP's #pragma omp simd (assuming version 4.0 or greater).

  • Sonar

    Write Clean C++ Code. Always.. Sonar helps you commit clean C++ code every time. With over 550 unique rules to find C++ bugs, code smells & vulnerabilities, Sonar finds the issues while you focus on the work.

  • kokkos

    Kokkos C++ Performance Portability Programming EcoSystem: The Programming Model - Parallel Execution and Memory Abstraction

  • mfem

    Lightweight, general, scalable C++ library for finite element methods

    Project mention: rodin alternatives - mfem and FreeFem-sources | libhunt.com/r/rodin | 2023-03-08
  • Kratos

    Kratos Multiphysics (A.K.A Kratos) is a framework for building parallel multi-disciplinary simulation software. Modularity, extensibility and HPC are the main objectives. Kratos has BSD license and is written in C++ with extensive Python interface. (by KratosMultiphysics)

    Project mention: Open-source FEA software | reddit.com/r/engineering | 2022-06-16
  • CTranslate2

    Fast inference engine for Transformer models

    Project mention: [D] Faster Flan-T5 inference | reddit.com/r/MachineLearning | 2023-02-22

    You can also check out the CTranslate2 library which supports efficient inference of T5 models, including 8-bit quantization on CPU and GPU. There is a usage example in the documentation.

  • dolfinx

    Next generation FEniCS problem solving environment

    Project mention: rodin alternatives - mfem and FreeFem-sources | libhunt.com/r/rodin | 2023-03-08
  • InfluxDB

    Access the most powerful time series database as a service. Ingest, store, & analyze all types of time series data in a fully-managed, purpose-built database. Keep data forever with low-cost storage and superior data compression.

  • oneMKL

    oneAPI Math Kernel Library (oneMKL) Interfaces

    Project mention: Stable Diffusion on AMD RDNA™ 3 Architecture | reddit.com/r/hardware | 2022-12-21

    I think there's already been work done to just use intel MKL on any device: https://github.com/oneapi-src/oneMKL

  • RAJA

    RAJA Performance Portability Layer (C++)

    Project mention: Cuda application question | reddit.com/r/CUDA | 2022-04-24

    Since the ability to use C++ parallel algorithms on the GPU is a relatively new thing, some applications have used other C++ abstraction libraries instead, such as Kokkos (https://kokkos.org/) and RAJA (https://github.com/LLNL/RAJA). These both have multiple backends that support GPUs and CPUs without needing to change your application code.

  • PothosCore

    The Pothos data-flow framework

  • feelpp

    :gem: Feel++: Finite Element Embedded Language and Library in C++

    Project mention: rodin alternatives - mfem and FreeFem-sources | libhunt.com/r/rodin | 2023-03-08
  • parlaylib

    A Toolkit for Programming Parallel Algorithms on Shared-Memory Multicore Machines

  • ConcurrentDeque

    Fast, generalized, implementation of the Chase-Lev lock-free work-stealing deque for C++17

  • CPURasterizer

    CPU Based Rasterizer Engine

  • Lazy

    Light-weight header-only library for parallel function calls and continuations in C++ based on Eric Niebler's talk at CppCon 2019.

  • Bulk

    A modern interface for implementing bulk-synchronous parallel programs.

  • cppRouting

    Algorithms for Routing and Solving the Traffic Assignment Problem

    Project mention: Using R to Cluster Points by Road Networks | reddit.com/r/Rlanguage | 2022-12-14

    cppRouting: I've just discovered this package. I use it if I require fast routing and can provide my own spatial graph data. So if I can't use OSM (maybe because of licence issues) this package will provide very fast results, too! I didn't compare the performance against the sfnetworks package, but I guess it's a lot faster and memory efficient especially for large networks. It also supports many implementations of different routing algorithms.

  • parallel-dfs-dag

    A parallel implementation of DFS for Directed Acyclic Graphs (https://research.nvidia.com/publication/parallel-depth-first-search-directed-acyclic-graphs)

  • cudnnxx

    cuDNN C++ wrapper.

  • kmer-signatures

    High-performance kmer-signatures
