* A40, A100, RTX 3080 Ti, RTX 3090, RTX 4090.
* 🤯: RTX 3090/4090 is faster than A40/A100 for gRASPA
* gRASPA has a SYCL version (experimental) that supports other devices, available in [Releases](https://github.com/snurr-group/gRASPA/releases)

### Pybind Extension (testing)
* Pybind extension for gRASPA allows user to interact with the **internal variables** of gRASPA, break down **MC moves**, add their **modifications**
* Access the pybind-gRASPA extension [here](https://github.com/Zhaoli2042/gRASPA_pybind), as a patch to the original code

## Quick Start
* Go to [```Examples/```](Examples/) folder and read more!
