init_compute_deviceT_init_compute_deviceInitComputeDeviceInitComputeDevice (Operator)
Name
init_compute_deviceT_init_compute_deviceInitComputeDeviceInitComputeDevice
— Initialize a compute device.
Signature
Description
init_compute_deviceinit_compute_deviceInitComputeDeviceInitComputeDeviceInitComputeDevice
initializes a compute device and prepares a
list of operators given in OperatorsOperatorsOperatorsOperatorsoperators
for the execution on this
device. Further the device is activated for the current thread.
If init_compute_deviceinit_compute_deviceInitComputeDeviceInitComputeDeviceInitComputeDevice
is not called or operators other than
those in OperatorsOperatorsOperatorsOperatorsoperators
are used on the device, the initialization
is performed on demand.
Use get_operator_infoget_operator_infoGetOperatorInfoGetOperatorInfoGetOperatorInfo
to test if an operator qualifies for
execution on the compute device.
Attention
Be aware that the execution time of init_compute_deviceinit_compute_deviceInitComputeDeviceInitComputeDeviceInitComputeDevice
depends
on the number of OperatorsOperatorsOperatorsOperatorsoperators
and may last up to several seconds.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: local (may only be called from the same thread in which the window, model, or tool instance was created).
- Processed without parallelization.

(input_control) string-array →
HTupleHTupleHtuple (string) (string) (HString) (char*)
List of operators to prepare.
Default value:
'all'
"all"
"all"
"all"
"all"
List of values: 'all'"all""all""all""all", 'derivate_gauss'"derivate_gauss""derivate_gauss""derivate_gauss""derivate_gauss", 'sobel_amp'"sobel_amp""sobel_amp""sobel_amp""sobel_amp"
Result
The operator init_compute_deviceinit_compute_deviceInitComputeDeviceInitComputeDeviceInitComputeDevice
returns the
value 2 (H_MSG_TRUE) if the initialization was successful. Otherwise
an exception will be raised.
