Top 23 C++ Performance Projects

  • C++ Format

    A modern formatting library

    Project mention: Print statement in JaVa | reddit.com/r/ProgrammerHumor | 2022-05-10

    Any idea how it compares to FMT?

  • Halide

    a language for fast, portable data-parallel computation

    Project mention: Currently, what are some of the worst things about C++? | reddit.com/r/cpp | 2022-04-28

    I also maintain the build system for Halide, but as it's less greenfield, there are some things I would need team buy-in to change. It's also much more complex (building code generators necessarily is). I'm still pretty happy with it, though. See here: https://github.com/halide/Halide

  • SonarQube

    Static code analysis for 29 languages.. Your projects are multi-language. So is SonarQube analysis. Find Bugs, Vulnerabilities, Security Hotspots, and Code Smells so you can release quality code every time. Get started analyzing your projects today for free.

  • tracy

    C++ frame profiler

    Project mention: Jane Street Magic-Trace | news.ycombinator.com | 2022-04-22

    If you aren't adverse to manual instrumentation there's also Tracy[1].

  • ArrayFire

    ArrayFire: a general purpose GPU library.

    Project mention: [D] Neural Networks using a generic GPU framework | reddit.com/r/MachineLearning | 2022-01-04

    Looking for frameworks with Julia + OpenCL I found array fire. It seems quite good, bonus points for rust bindings. I will keep looking for more, Julia completely fell off my radar.

  • hotspot

    The Linux perf GUI for performance analysis.

    Project mention: Linux Perf Examples | news.ycombinator.com | 2022-03-18

    > [...] how Perf compares to vendor tools like vTune [...] ?

    Regarding the hardware events that Perf can capture on x86, it has pretty much all of them. So it should be equivalent to vTune for all practical purposes.

    The big difference is in the UI -- or absence thereof. Perf is a low-level tool and its output is mostly text files. There is a curses-based TUI for perf-report (and even gtk version, but it is essentially the same as the TUI, just using GTK2 widgets), but that's about it.

    By contrast, vTune comes with a heavy (electron-based?) GUI and is quite helpful in guiding beginners, with many graphs and explanations.

    Of course, one can (and is expected to) complement Perf with an assortment of tools that process its output for visualization. For example, the flamegraph [1] and heat map [2] tools described in the article. But also KDAB hotspot [3] or HPerf for a vTune-style perf-report.

    C/C++ Performance Profiler

    Project mention: How come I can only see the main page on master branch? | reddit.com/r/git | 2022-04-06

    If using the command line, just open gitk. If using GitHub, look under the network tab.

  • palanteer

  • ultimatepp

    U++ is a C++ cross-platform rapid application development framework focused on programmer's productivity. It includes a set of libraries (GUI, SQL, Network etc.), and integrated development environment (TheIDE).

    Project mention: New 3.1.6 release of wxWidgets, free and open source library for creating portable native GUI applications, adding transparent support for high DPI artwork and much more, is now available. | reddit.com/r/cpp | 2022-04-05

    Have you tried Ultimate++? It's cross-platform, but unlike Qt, it uses native widgets on Windows.

  • reckless

    Reckless logging. Low-latency, high-throughput, asynchronous logging library for C++.

  • oneMKL

    oneAPI Math Kernel Library (oneMKL) Interfaces

  • timemory

    Modular C++ Toolkit for Performance Analysis and Logging. Profiling API and Tools for C, C++, CUDA, Fortran, and Python. The C++ template API is essentially a framework to creating tools: it is designed to provide a unifying interface for recording various performance measurements alongside data logging and interfaces to other tools.

    Project mention: Best way to track cpu and i/o time? | reddit.com/r/cpp | 2021-10-29

    timemory is my recommendation as the backend if you want to build something custom

  • flamethrower

  • opencl-intercept-layer

    Intercept Layer for Debugging and Analyzing OpenCL Applications

    Project mention: Useful Tools and Programs list for OpenCL | reddit.com/r/OpenCL | 2022-03-28

    Somewhat selfishly, one of the tools I see missing from your guide is the OpenCL Intercept Layer. This is an open-source tool we've developed and we use it every day to debug and analyze OpenCL programs.

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). The latest post mention was on 2022-05-10.
