CUDA C Swift Package

CCUDA

C CUDA system module for Swift

This provides a direct C bridge. For native Swift CUDA APIs, cuda-swift is under active development. cuda-swift uses the CCUDA bridge.

Components

import CCUDA              // Equivalent to #include <cuda.h>
import CCUDARuntime       // Equivalent to #include <cuda_runtime.h>
import CNVRTC             // Equivalent to #include <nvrtc.h>
import CCuBLAS            // Equivalent to #include <cublas_v2.h>
import CNVBLAS            // Equivalent to #include <nvblas.h>
import CCuDNN             // Equivalent to #include <cudnn.h>

Dependencies

One or more of the following modules are required, when and only when you import them.

CUDA at /usr/local/cuda/

NVRTC at /usr/local/cuda/

cuBLAS at /usr/local/cuda/

NVBLAS at /usr/local/cuda/

cuDNN at /usr/local/cuda/

For instance, if you only need to use the CUDA driver library while you don't have cuBLAS/nvBLAS/cuDNN installed, the module will compile, instead of asking you to install uncessary libraries.

Use it in your Swift package

Add a dependency:

.Package(url: "https://github.com/rxwei/CCUDA", majorVersion: 1)

You'll need to specify the path to your CUDA headers and library at swift build. For example:

swift build -Xcc -I/usr/local/cuda/include -Xlinker -L/usr/local/cuda/lib
