名称

签名
Herror T_init_compute_device(const Htuple DeviceHandle, const Htuple 算子)
描述
init_compute_deviceinit_compute_deviceInitComputeDeviceInitComputeDeviceInitComputeDeviceinit_compute_device initializes a compute device and prepares a
list of operators given in 算子算子算子算子算子算子 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 算子算子算子算子算子算子 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.
注意
Be aware that the execution time of init_compute_deviceinit_compute_deviceInitComputeDeviceInitComputeDeviceInitComputeDeviceinit_compute_device depends
on the number of 算子算子算子算子算子算子 and may last up to several seconds.
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。
