librtcx

RTCX (runtime-compiler extended) is a wrapper around NVRTC and nvJitLink designed to provide:

• User-controlled compilation, linking, caching, and pre-loading of CUDA kernels
• Zero-copy interfaces to manage JIT compilation and linking
• CMake script to embed compressed headers directly into an executable without incurring overhead at runtime on every compilation request
• Facilities to pre-load and teardown dynamic library dependencies (libcuda, libnvrtc, and libnvJitLink)

Platforms Supported

• Linux

• libzstd
• xxHash
• CUDA >= 12.2
