IDMLDevice1 interface (directml.h)
Represents a DirectML device, which is used to create operators, binding tables, command recorders, and other objects. The IDMLDevice1 interface inherits from IDMLDevice.
A DirectML device is always associated with exactly one underlying Direct3D 12 device. All objects created by the DirectML device maintain a strong reference to their parent device. Unlike the Direct3D 12 device, the DML device is not a singleton. Therefore, it's possible to create multiple DirectML devices over the same Direct3D 12 device. However, this isn't recommended as the DirectML device has no mutable state, so there's little advantage to creating multiple DML devices over the same Direct3D 12 device.
This object is thread-safe.
