TensorRT
NVIDIA® TensorRT™ is an SDK for high-performance deep learning inference on NVIDIA GPUs. This repository contains the open source components of TensorRT.
Project mention: Generative AI Interview for Senior Data Scientists: 50 Key Questions and Answers | dev.to | 2025-05-06What is the purpose of using ONNX or TensorRT for deployment? When deploying a trained deep learning model into a real-world service environment for inference, optimization to increase execution speed and reduce resource consumption is crucial. ONNX and TensorRT are prominent tools and frameworks widely used for this purpose.

OpenCL-Wrapper
OpenCL is the most powerful programming language ever created. Yet the OpenCL C++ bindings are cumbersome and the code overhead prevents many people from getting started. I created this lightweight OpenCL-Wrapper to greatly simplify OpenCL software development with C++ while keeping functionality and performance.

ParallelReductionsBenchmark
Thrust, CUB, TBB, AVX2, AVX-512, CUDA, OpenCL, OpenMP, Metal, and Rust - all it takes to sum a lot of numbers fast!
I was asked this a few months back but don’t have the measurements fresh anymore. In general, I think TBB is one of the more thorough and feature-rich parallelism libraries out there. That said, I just found a comparable usage example in my benchmarks, and it doesn’t look like TBB will have the same low-latency profile as Fork Union: https://github.com/ashvardanian/ParallelReductionsBenchmark/...
