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.

Project mention: How exactly would you go about writing a program to simplify algebraic expressions? | reddit.com/r/cpp_questions | 2023-01-20
https://beltoforion.de/en/muparser/ is a good example of such a parser.

Does anyone know what's the way to help with the OM-1 camera support? There's a PR that works really well (https://github.com/darktable-org/rawspeed/pull/357).

I wrote the Fortran version of BabelStream (https://github.com/UoB-HPC/BabelStream/pull/135) to compare all of these, which might be useful as well. There is also MiniWeather, which supports all OpenMP, OpenACC and StdPar for GPU: https://github.com/mrnorman/miniWeather/tree/main/fortran.

mixbench
A GPU benchmark tool for evaluating GPUs and CPUs on mixed operational intensity kernels (CUDA, OpenCL, HIP, SYCL, OpenMP)

Project mention: 1000x speedup on interactive Mandelbrot zooms: from C, to inline SSE assembly, to OpenMP for multiple cores, to CUDA, to pixel-reuse from previous frames, to inline AVX assembly... | reddit.com/r/programming | 2022-07-16
I verified that the limiting factor is memory bandwidth - and that once we switch to a fully CPU-bound mode (with option -p 100) the computation speed scales linearly with more cores.

ParallelReductionsBenchmark
Thrust, CUB, TBB, AVX2, CUDA, OpenCL, OpenMP, SyCL - all it takes to sum a lot of numbers fast!

parallel-cellular-automata
Framework for building parallel cellular automata in C++. In it you can also find a work-stealing threadpool and a reusable barrier that you can use in other projects.
Project mention: Small C++ framework for building parallel cellular automata | reddit.com/r/cellular_automata | 2022-08-07A few months back I made a small framework for building parallel cellular automata in C++ for a university project. The code is here: https://github.com/gerzin/parallel-cellular-automata. Let me know what do you think about it.
