Member Data Documentation

◆ primitive_kind

dnnl_primitive_kind_t dnnl_convolution_desc_t::primitive_kind

The kind of primitive.

Used for self-identifying the primitive descriptor. Must be dnnl_convolution.

◆ prop_kind

dnnl_prop_kind_t dnnl_convolution_desc_t::prop_kind

◆ alg_kind

dnnl_alg_kind_t dnnl_convolution_desc_t::alg_kind

The kind of the convolution algorithm.

Possible values: dnnl_convolution_direct.

◆ padding

dnnl_dims_t dnnl_convolution_desc_t::padding[2]

Padding in each spatial dimension.

padding[0] is a padding in the beginning (padding_l), padding[1] is a padding in the end (padding_r).
