Member Data Documentation

primitive_kind

mkldnn_primitive_kind_t mkldnn_eltwise_desc_t::primitive_kind

The kind of primitive.

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

prop_kind

mkldnn_prop_kind_t mkldnn_eltwise_desc_t::prop_kind

The kind of propagation.

Possible values: mkldnn_forward_training, mkldnn_forward_inference, mkldnn_backward, and mkldnn_backward_data.

alg_kind

mkldnn_alg_kind_t mkldnn_eltwise_desc_t::alg_kind

The kind of eltwise algorithm.

Possible values: mkldnn_eltwise_relu, mkldnn_eltwise_tanh, mkldnn_eltwise_elu, mkldnn_eltwise_square, mkldnn_eltwise_abs, mkldnn_eltwise_sqrt, mkldnn_eltwise_linear, mkldnn_eltwise_bounded_relu, mkldnn_eltwise_soft_relu, mkldnn_eltwise_logistic and mkldnn_eltwise_exp.

alpha

float mkldnn_eltwise_desc_t::alpha

Algorithm specific parameter.

Accordance table:

• mkldnn_eltwise_relu: alpha – negative slope, beta ignored
• mkldnn_eltwise_tanh: alpha and beta ignored
• mkldnn_eltwise_elu: alpha – negative slope, beta ignored
• mkldnn_eltwise_square: alpha and beta ignored
• mkldnn_eltwise_abs: alpha and beta ignored
• mkldnn_eltwise_sqrt: alpha and beta ignored
