NVIDIA NVJITLink

NVIDIA NVJITLink is a Python package that distributes the native NVIDIA NVJITLink shared library (libnvjitlink). This library provides JIT (Just-In-Time) compilation services for NVIDIA GPU code, acting as a low-level component within the NVIDIA ecosystem. It's primarily used as a backend dependency by higher-level Python libraries and frameworks (e.g., Numba, CuPy, PyTorch with NVFuser) that need to compile GPU kernels at runtime. Its version is often tightly coupled with the NVIDIA CUDA Toolkit version. The current version is 13.2.51, and it's updated in conjunction with CUDA Toolkit releases.
