Device object

class dpnp.tensor.Device(*args, **kwargs)

An object representing Data-API concept of device.

This is a wrapper around dpctl.SyclQueue with custom formatting. The class does not have public constructor, but a class method dpnp.tensor.Device.create_device() to construct it from device keyword argument in Array-API functions.

Instance can be queried for sycl_queue, sycl_context, or sycl_device.

create_device([device])	Creates instance of Device from argument.
sycl_queue	dpctl.SyclQueue used to offload to this Device.
sycl_device	dpctl.SyclDevice targeted by this Device.
sycl_context	dpctl.SyclContext associated with this Device.
print_device_info()	Outputs information about targeted SYCL device
wait()	Call wait method of the underlying sycl_queue.
