 ### Experiment Root Directory
-Every experiment has a root folder, which is shown on the right-top corner of webUI.

-> For flexibility, we also offer a `logDir` option in your configuration, which specifies the directory to store all experiments (defaults to `~/nni/experiment`). Please refer to [Configuration](ExperimentConfig.md) for more details.

 Under that directory, there is another directory named `log`, where `nnimanager.log` and `dispatcher.log` are placed.
