NVIDIA Runtime Compiler
nvrtc
The NVIDIA Runtime Compiler (nvrtc) is a runtime compilation library for CUDA
C. It compiles CUDA C++ to
PTX without requiring
a separate launch of the
NVIDIA CUDA Compiler Driver (nvcc) in
another process. It is used by some libraries or frameworks to, for example, map
generated C/C++ code to
PTX code that can run
on a GPU.
Note that this PTX is then further JIT-compiled from the PTX IR to the SASS assembly . This is done by the NVIDIA GPU drivers and is distinct from the compilation done by NVRTC. CUDA binaries that contain PTX , as required for forward compatibility, also pass through this compilation step.
NVRTC is closed source. You can find its documentation here .
