get_compute_device_paramT_get_compute_device_paramGetComputeDeviceParamGetComputeDeviceParam (Operator)

Name

get_compute_device_paramT_get_compute_device_paramGetComputeDeviceParamGetComputeDeviceParam — Query compute device parameters.

Signature

Description

get_compute_device_paramget_compute_device_paramGetComputeDeviceParamGetComputeDeviceParamGetComputeDeviceParam returns parameters of the compute device DeviceHandleDeviceHandleDeviceHandleDeviceHandledeviceHandle for the current HALCON thread.

The following parameters can be queried (for more detailed descriptions sie set_compute_device_paramset_compute_device_paramSetComputeDeviceParamSetComputeDeviceParamSetComputeDeviceParam):

'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.

Parameters

Result

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