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.

Global Functions

dnnl_status_t DNNL_API dnnl_graph_op_create(
    dnnl_graph_op_t* op,
    size_t id,
    dnnl_graph_op_kind_t kind,
    const char* verbose_name
    )

Initializes an op with unique id, kind, and name.

Parameters:

op	Output op
id	The unique id of the output op.
kind	The op kind.
verbose_name	The string added as the op name.

Returns:
