## Requirements
MatX support is currently limited to **Linux only** due to the time to test Windows. If you'd like to voice your support for native Windows support using Visual Studio, please comment on the issue here: https://github.com/NVIDIA/MatX/issues/153.

**Note**: CUDA 12.0.0 through 12.2.0 have an issue that causes building MatX unit tests to show a compiler error or cause a segfault in the compiler. Please use CUDA 11.5-11.8 or CUDA 12.2.1+ with MatX.

MatX is using features in C++17 and the latest CUDA compilers and libraries. For this reason, when running with GPU support, CUDA 11.5 and g++9, nvc++ 24.5, or clang 17 or newer is required. You can download the CUDA Toolkit [here](https://developer.nvidia.com/cuda-downloads).

MatX has been tested on and supports Pascal, Turing, Volta, Ampere, Ada, and Hopper GPU architectures. Jetson products are supported with Jetpack 5.0 or above.

System Requirements
-------------------
MatX requires **CUDA 11.5** or higher, and **g++ 9.3+**, **clang 17+**, or **nvc++ 24.5** for the host compiler. See the CUDA toolkit documentation
