 ```
 * sess_options.session_thread_pool_size=2 controls how many thread do you want to use to run your model
 * sess_options.enable_sequential_execution=True controls whether you want to run operators in your graph sequentially or in parallel. Usually when your model has many branches, set this option to false will give you better performance.

 ### MKL_DNN/nGraph/MKL_ML Execution Provider
 MKL_DNN, MKL_ML and nGraph all depends on openmp for parallization. For those execution providers, we need to use openmp enviroment variable to tune the performance.
