Some convolution algorithms in cuDNN use additional GPU memory as a temporary buffer. This is called “workspace,” and users can adjust the upper limit of its size. By increasing the limit of workspace size, cuDNN may be able to use better (i.e., memory consuming but faster) algorithm. The default size (in bytes) is: May also be a callable that takes numpy.ndarray or cupy.ndarray and edits its value.
