Description
get_compute_device_paramget_compute_device_paramGetComputeDeviceParamGetComputeDeviceParamGetComputeDeviceParamget_compute_device_param returns parameters of the
compute device DeviceHandleDeviceHandleDeviceHandleDeviceHandledeviceHandledevice_handle for the current HALCON thread.
The following parameters can be queried (for more information
see set_compute_device_paramset_compute_device_paramSetComputeDeviceParamSetComputeDeviceParamSetComputeDeviceParamset_compute_device_param):
- 'alloc_pinned'
-
If 'true', the output image matrices of all operators
are created in page locked (so called 'pinned') memory.
- 'asynchronous_execution'
-
If 'true', operators executed on the compute device
do not wait for the device computations to finish but
return after initiation the computations.
- 'buffer_cache_capacity'
-
Maximum size (in bytes) of the compute device buffer cache.
- 'buffer_cache_used'
-
Current size (in bytes) of the compute device buffer cache.
- 'image_cache_capacity'
-
Maximum size (in bytes) of the compute device image cache.
- 'image_cache_used'
-
Current size (in bytes) of the compute device image cache.
- 'pinned_mem_cache_capacity'
-
Maximum size (in bytes) of the page locked (pinned) memory
cache.
- 'pinned_mem_cache_used'
Current size (in bytes) of the page locked (pinned) memory
cache.
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.

Result
The operator get_compute_device_paramget_compute_device_paramGetComputeDeviceParamGetComputeDeviceParamGetComputeDeviceParamget_compute_device_param returns the
value 2 (H_MSG_TRUE) if the parameters are correct. Otherwise
an exception will be raised.
