Cuda 11.0 : libcublas_device not found

Hello,

This is the link to the release notes of cuda 11.0. https://docs.nvidia.com/cuda/cuda-toolkit-release-notes/index.html .
It says that it supports:

  • cublas (BLAS) and
  • cublas_device (BLAS Kernel Interface).
    Hence, my simple question: where is it? there is no library for cublas_device inside cuda 11.0 toolkit.

Kind regards,

So, should I understand that the official release notes do not correspond to the released toolkit ?
