Descriptor for reduction.
Construction
desc()
Default constructor. Produces an empty object.
desc( algorithm aalgorithm, const memory::desc& src_desc, const memory::desc& dst_desc, float p, float eps )
Constructs a descriptor for a reduction primitive using algorithm specific parameters, source and destination memory descriptors.
Destination memory descriptor may be initialized with dnnl::memory::format_tag::any value of
format_tag
. Parameters:
aalgorithm | reduction algorithm kind. 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. |
p | algorithm specific parameter. |
eps | algorithm specific parameter. |
src_desc | Source memory descriptor. |
dst_desc | Destination memory descriptor. |
