select_device_with_aspects	Selects the root dpctl.SyclDevice that has the highest default selector score among devices that have all aspects in the required_aspects list, and do not have any aspects in excluded_aspects list.

Platform discovery

get_devices	Returns a list of dpctl.SyclDevice instances selected based on the given dpctl.device_type and dpctl.backend_type values.
lsplatform	Prints out the list of available SYCL platforms, and optionally extra metadata about each platform.
get_num_devices	A helper function to return the number of SYCL devices of a given dpctl.device_type and dpctl.backend_type.
has_gpu_devices	A helper function to check if there are any SYCL GPU devices available.
has_cpu_devices	A helper function to check if there are any SYCL CPU devices available.
has_accelerator_devices	A helper function to check if there are any SYCL Accelerator devices available.

Exceptions

SyclDeviceCreationError	A SyclDeviceCreationError exception is raised when SyclDevice instance could not created.
SyclContextCreationError	A SyclContextCreationError exception is raised when SyclContext could not created.
SyclQueueCreationError	A SyclQueueCreationError exception is raised when a SyclQueue could not be created.
SyclSubDeviceCreationError	A SyclSubDeviceCreationError exception is raised by SyclDevice.create_sub_devices() when SyclDevice instance could not be partitioned into sub-devices.

Utilities
