C++ API

The FlexFlow backend is at the core of FlexFlow Train and FlexFlow Serve. It is written entirely in C/C++ and CUDA/HIP. This section documents the API, which is generated by Doxygen and it is available at the following links:

• CUDA version (default version)

• HIP version

The two versions only differ when it comes to the GPU kernels, so the great majority of the entries are identical. If you are unsure which version to use, take a look at the CUDA version.
