Verbose mode

It is possible to enable tracing execution of plugin nodes to cout and collect statistics, such as:

• node implementer:
  • cpu (CPU plugin)
  • dnnl (oneDNN library)
  • ngraph_ref (ngraph reference fallback)
• node name
• node type
• node algorithm
• node primitive info
• input / output ports info
• fused nodes
• execution time
• etc

Format:

    ov_cpu_verbose,exec,<node_implemeter>,\
    <node_name>:<node_type>:<node_alg>,<impl_type>,\
    src:<port_id>:<precision>::<type>:<format>:f0:<shape> ...,\
    dst:<port_id>:<precision>::<type>:<format>:f0:<shape> ...,\
    post_ops:'<node_name>:<node_type>:<node_alg>;...;',\
    <execution_time>

To turn on verbose mode the following environment variable should be used:

    OV_CPU_VERBOSE=<level> binary ...

Levels enable printing of:

• 1 - executable nodes only
• 2 - same as 1 plus Input and Output nodes
• 3 - same as 2 plus constant path nodes (executed in scope of compile_model())

To have colored verbose output just duplicate level's digit, for example:

    OV_CPU_VERBOSE=11 binary ...

NOTE: Shell color codes are used
