Rust binding to CUDA Driver (libcuda.so) and Runtime (libcudart.so) APIs

This crate does NOT include CUDA itself. You need to install on your own.

CUDA Installation

  • You should install CUDA from the official installer.
  • or use nvidia/cuda container
    • This container does not add libcuda.so to dynamic link path. You need to add it to your ld path LD_LIBRARY_PATH=/usr/local/cuda/lib64/stubs or using ldconfig.

CUDA_LIBRARY_PATH environment variable

  • If you use system installer (e.g. apt, yum, pacman, and so on), the install path may be different.
  • $CUDA_LIBRARY_PATH (e.g. /opt/cuda/lib64) environment value adds paths to the list of library searching.
  • To verify that cuda-sys can find your CUDA installation, you can check that the CUDA_PATH environment variable has been set.

Q & A

Q. Program does not start (can be compiled) with following error message:

error while loading shared libraries: libcuda.so.1: cannot open shared object file: No such file or directory

A. Driver API (libcuda.so) is sometimes installed in a separate directory. You need to find it, and add to LD_LIBRARY_PATH:
