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?

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).

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)

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.

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

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.

ConcurrentDeque
Fast, generalized, implementation of the Chase-Lev lock-free work-stealing deque for C++17
-
-
Lazy
Light-weight header-only library for parallel function calls and continuations in C++ based on Eric Niebler's talk at CppCon 2019.

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)
