rust-cuBLAS • Join the chat at Build Status Coverage Status License

rust-cuBLAS provides a safe wrapper for CUDA's cuBLAS library, so you can use cuBLAS comfortably and safely in your Rust application.

As cuBLAS currently relies on CUDA to allocate memory on the GPU, you might also look into rust-cuda.

rust-cublas was developed at [Autumn][autumn] for the Rust Machine Intelligence Framework Leaf.

rust-cublas is part of the High-Performance Computation Framework Collenchyma, for the BLAS Plugin. For an easy, unified interface for BLAS operations, such as those provided by cuBLAS, you might check out Collenchyma.

For more information,

Getting Started

If you're using Cargo, just add rust-cuBLAS to your Cargo.toml:

cublas = "0.2.0"

If you're using Cargo Edit, you can call:

$ cargo add cublas


rust-cublas depends on the cuBLAS runtime libraries, which can be obtained from NVIDIA.

Manual Configuration

rust-cublas's build script will by default attempt to locate cublas via pkg-config. This will not work in some situations, for example,

  • on systems that don't have pkg-config,
  • when cross compiling, or
  • when cuBLAS is not installed in the default system library directory (e.g. /usr/lib).

Therefore the build script can be configured by exporting the following environment variables:

    If specified, a directory that will be used to find cuBLAS runtime libraries. e.g. /opt/cuda/lib

    If specified, cuBLAS libraries will be statically rather than dynamically linked.

    If specified, will be used to find cuBLAS libraries under a different name.

If either CUBLAS_LIB_DIR or CUBLAS_INCLUDE_DIR are specified, then the build script will skip the pkg-config step.

If your also need to run the compiled binaries yourself, make sure that they are available:

# Linux; for other platforms consult the instructions that come with cuBLAS
cd <cublas_installpath>
