Benchmark usage
===============

This part contains the usage of MACE benchmark tools.

Overview
--------

As mentioned in the previous part, there are two kinds of benchmark tools,
one for operator and the other for model.

Operator Benchmark
------------------

Operator Benchmark is used for test and optimize the performance of specific operator.

=====
Usage
=====

    .. code:: bash

        python tools/bazel_adb_run.py --target="//test/ccbenchmark:mace_cc_benchmark" --run_target=True  --args="--filter=.*BM_CONV.*"

======
Output
======

    .. code:: bash

        Benchmark                                                    Time(ns) Iterations Input(MB/s)   GMACPS

    * - Options
      - Usage
    * - Benchmark
      - Benchmark unit name.
    * - Time
      - Time of one round.
    * - Iterations
      - the number of iterations to run, which is between 10 and 1000,000,000. the value is calculated based on the strategy total run time does not exceed 1s.
    * - Input
      - The bandwidth of dealing with input. the unit is MB/s.
    * - GMACPS
      - The speed of running MACs(multiply-accumulation). the unit is G/s.

Model Benchmark
---------------

Model Benchmark is used for test and optimize the performance of your model.
This tool could record the running time of the model and the detailed running information of each operator of your model.

=====
Usage
=====

    .. code:: bash

        python tools/converter.py run --config=/path/to/your/model_deployment.yml --benchmark
