Name

init_compute_deviceT_init_compute_deviceInitComputeDeviceInitComputeDeviceinit_compute_device — Initialize a compute device.

Signature

init_compute_device( : : DeviceHandle, Operators : )

Herror T_init_compute_device(const Htuple DeviceHandle, const Htuple Operators)

void InitComputeDevice(const HTuple& DeviceHandle, const HTuple& Operators)

void HComputeDevice::InitComputeDevice(const HTuple& Operators) const

static void HOperatorSet.InitComputeDevice(HTuple deviceHandle, HTuple operators)

void HComputeDevice.InitComputeDevice(HTuple operators)

def init_compute_device(device_handle: HHandle, operators: Sequence[str]) -> None

Description

init_compute_deviceinit_compute_deviceInitComputeDeviceInitComputeDeviceInitComputeDeviceinit_compute_device initializes a compute device and prepares a list of operators given in OperatorsOperatorsOperatorsOperatorsoperatorsoperators for the execution on this device. Further the device is activated for the current thread. If init_compute_deviceinit_compute_deviceInitComputeDeviceInitComputeDeviceInitComputeDeviceinit_compute_device is not called or operators other than those in OperatorsOperatorsOperatorsOperatorsoperatorsoperators are used on the device, the initialization is performed on demand.

Use get_operator_infoget_operator_infoGetOperatorInfoGetOperatorInfoGetOperatorInfoget_operator_info to test if an operator qualifies for execution on the compute device.

Attention

Be aware that the execution time of init_compute_deviceinit_compute_deviceInitComputeDeviceInitComputeDeviceInitComputeDeviceinit_compute_device depends on the number of OperatorsOperatorsOperatorsOperatorsoperatorsoperators and may last up to several seconds.

List of operators to prepare.

Default value: 'all' "all" "all" "all" "all" "all"

List of values: 'all'"all""all""all""all""all", 'derivate_gauss'"derivate_gauss""derivate_gauss""derivate_gauss""derivate_gauss""derivate_gauss", 'sobel_amp'"sobel_amp""sobel_amp""sobel_amp""sobel_amp""sobel_amp"

Result

The operator init_compute_deviceinit_compute_deviceInitComputeDeviceInitComputeDeviceInitComputeDeviceinit_compute_device returns the value 2 (H_MSG_TRUE) if the initialization was successful. Otherwise an exception will be raised.
