Scheduler API reference
***********************
The scheduler is exposed to the experiments via a virtual device called ``scheduler``. It can be requested like any regular device, and then the methods below can be called on the returned object.
The scheduler virtual device also contains the attributes ``rid``, ``pipeline_name``, ``priority`` and ``expid`` that contain the corresponding information about the current run.
