Detailed Documentation
OP is an abstraction of computation logic for deep neural network operations.
An op object encapsulates an operation kind which describes the computation logic, an unique ID which differentiates operations with the same kind, and logical tensors which describes the input and output of the operation and its connections to other operations in the graph.
Typedefs
typedef struct dnnl_graph_op* dnnl_graph_op_t
An operation handle.
typedef const struct dnnl_graph_op* const_dnnl_graph_op_t
A constant operation handle.
