描述

get_compute_device_paramget_compute_device_paramGetComputeDeviceParamGetComputeDeviceParamGetComputeDeviceParamget_compute_device_param returns parameters of the compute device DeviceHandleDeviceHandleDeviceHandleDeviceHandledeviceHandledevice_handle for the current HALCON thread in GenParamValueGenParamValueGenParamValueGenParamValuegenParamValuegen_param_value。

The following parameters can be queried (for more information see set_compute_device_paramset_compute_device_paramSetComputeDeviceParamSetComputeDeviceParamSetComputeDeviceParamset_compute_device_param) by setting them for GenParamNameGenParamNameGenParamNameGenParamNamegenParamNamegen_param_name:

'alloc_pinned'"alloc_pinned""alloc_pinned""alloc_pinned""alloc_pinned""alloc_pinned"

If 'true'"true""true""true""true""true", the output image matrices of all operators are created in page locked (so called 'pinned') memory.

'asynchronous_execution'"asynchronous_execution""asynchronous_execution""asynchronous_execution""asynchronous_execution""asynchronous_execution"

If 'true'"true""true""true""true""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'"buffer_cache_capacity""buffer_cache_capacity""buffer_cache_capacity""buffer_cache_capacity""buffer_cache_capacity"

Maximum size (in bytes) of the compute device buffer cache.

'buffer_cache_used'"buffer_cache_used""buffer_cache_used""buffer_cache_used""buffer_cache_used""buffer_cache_used"

Current size (in bytes) of the compute device buffer cache.

'image_cache_capacity'"image_cache_capacity""image_cache_capacity""image_cache_capacity""image_cache_capacity""image_cache_capacity"

Maximum size (in bytes) of the compute device image cache.

'image_cache_used'"image_cache_used""image_cache_used""image_cache_used""image_cache_used""image_cache_used"

Current size (in bytes) of the compute device image cache.

'pinned_mem_cache_capacity'"pinned_mem_cache_capacity""pinned_mem_cache_capacity""pinned_mem_cache_capacity""pinned_mem_cache_capacity""pinned_mem_cache_capacity"

Maximum size (in bytes) of the page locked (pinned) memory cache.

'pinned_mem_cache_used'"pinned_mem_cache_used""pinned_mem_cache_used""pinned_mem_cache_used""pinned_mem_cache_used""pinned_mem_cache_used"

Current size (in bytes) of the page locked (pinned) memory cache.

执行信息

• 多线程类型：可重入（与非独占算子并行运行）。
• 多线程作用域：局部（仅可在创建窗口、模型或工具实例的同一线程中调用）。
• 未采用并行化处理。
