Name
init_compute_deviceT_init_compute_deviceInitComputeDeviceInitComputeDeviceinit_compute_device — Initialize a compute device.
Signature
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.
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.
Parameters

List of operators to prepare.
Default value:
'all'
"all"
"all"

Result
The operator init_compute_deviceinit_compute_deviceInitComputeDeviceInitComputeDeviceInitComputeDeviceinit_compute_device returns the
value TRUE if the initialization was successful. Otherwise
an exception will be raised.
