Member Function Documentation

src_iter_desc()

memory::desc dnnl::lstm_backward::primitive_desc::src_iter_desc ( ) const

inline

Queries source recurrent hidden state memory descriptor.

Returns a zero_md if no src_iter was specified at op_desc creation time.

bias_desc()

memory::desc dnnl::lstm_backward::primitive_desc::bias_desc ( ) const

inline

Queries bias memory descriptor.

Returns a zero_md if no bias was specified at op_desc creation time.

dst_iter_desc()

memory::desc dnnl::lstm_backward::primitive_desc::dst_iter_desc ( ) const

inline

Queries destination recurrent hidden state memory descriptor.

Returns a zero_md if no dst_iter was specified at op_desc creation time.

workspace_desc()

memory::desc dnnl::lstm_backward::primitive_desc::workspace_desc ( ) const

inline

Queries workspace memory descriptor.

Returns a zero_md if no worspace is required.

diff_src_iter_desc()

memory::desc dnnl::lstm_backward::primitive_desc::diff_src_iter_desc ( ) const

inline

Queries diff source recurrent hidden state memory descriptor.

Returns a zero_md if no diff_src_iter was specified at op_desc creation time.

diff_dst_iter_desc()

memory::desc dnnl::lstm_backward::primitive_desc::diff_dst_iter_desc ( ) const

inline

Queries diff destination recurrent hidden state memory descriptor.

Returns a zero_md if no diff_dst_iter was specified at op_desc creation time.
