• Taskflow

  24 9,608 7.9 C++

  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.

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)?

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

  1 2,484 0.0 C++

  A C++ library of Concurrent Data Structures

• HPX

  15 2,418 9.8 C++

  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

  31 2,340 7.8 C++

  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

  16 2,083 1.2 C++

  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
