Detailed Documentation¶
A descriptor of reduction operation.
Fields¶
dnnl_primitive_kind_t primitive_kind
The kind of primitive.
Used for self-identifying the primitive descriptor. Must be dnnl_reduction.
dnnl_alg_kind_t alg_kind
The kind of reduction algorithm.
Possible values: dnnl_reduction_max, dnnl_reduction_min, dnnl_reduction_sum, dnnl_reduction_mul, dnnl_reduction_mean, dnnl_reduction_norm_lp_max, dnnl_reduction_norm_lp_sum, dnnl_reduction_norm_lp_power_p_max, dnnl_reduction_norm_lp_power_p_sum.
dnnl_memory_desc_t src_desc
Source memory descriptor.
dnnl_memory_desc_t dst_desc
Destination memory descriptor.
float p
Algorithm specific parameters.
