Member	Description
moduleId	Module ID. You are advised to set this parameter to 33, indicating the application. In this situation, the memory is allocated by the user application, which facilitates fault locating in maintenance and debugging scenarios.
deviceId	Device ID. If the device ID configured here is different from the device ID used for compute, an error is reported. You are advised not to set this parameter.
vaFlag	Whether to use the virtual address (VA) consistency function when the host memory is allocated by using the aclrtMallocHostWithCfg call. 0 (default value): The function is not used. 1: The function is used. After the host memory is registered by using the aclrtHostRegister call, the returned devPtr is the same as the ptr (indicating the host memory address). The host and device can use the same VA for access. Only some product models support the VA consistency function. For those not supporting this function, an error is reported when this function is used. The following product models support this function: Atlas A3 training products/Atlas A3 inference products Atlas A2 training products/Atlas A2 inference products
rsv	Reserved. The value is fixed at 0.
