Function

Sets the timeout interval (in seconds) for operator execution. If this API is called multiple times in a process, the last configured interval is used. If a timeout interval is carried during operator delivery, the timeout interval takes precedence over the timeout interval set by this API.

For the Ascend 950PR/Ascend 950DT, Atlas A3 training products/Atlas A3 inference products and Atlas A2 training products/Atlas A2 inference products, you are advised to use the aclrtSetOpExecuteTimeOutV2 API, which returns the timeout interval that actually takes effect.

Prototype

aclError aclrtSetOpExecuteTimeOut(uint32_t timeout)

Parameters

Parameter	Input/Output	Description
timeout	Input	Timeout interval, in seconds. 0 means to use the maximum timeout interval.

Parameter

Input/Output

Description

timeout

Input

Timeout interval, in seconds.

0 means to use the maximum timeout interval.

Returns

0 on success; otherwise, failure. For details, see aclError.

Restrictions

If this API is not called, the default timeout interval of AI Core and AI CPU operators varies depending on the product model.
- For the Ascend 950PR/Ascend 950DT, the default timeout interval of AI Core operators is 1,091s, and that of AI CPU operators is 28s.
- For the Atlas A3 training products/Atlas A3 inference products, the default timeout interval of AI Core operators is 1,091s, and that of AI CPU operators is 60s.
- For the Atlas A2 training products/Atlas A2 inference products, the default timeout interval of AI Core operators is 1,091s, and that of AI CPU operators is 28s.
- For the Atlas 200I/500 A2 inference products, the default timeout interval of AI Core operators is 1,091s, and that of AI CPU operators is 28s.
- For the Atlas inference products, the default timeout interval of AI Core operators is 547s, and that of AI CPU operators is 28s.
- For the Atlas training products, the default timeout interval of AI Core operators is 68s, and that of AI CPU operators is 28s.
The maximum timeout interval of AI Core and AI CPU operators varies depending on the architecture of the product model.
- For the product models below, the maximum timeout is interval × 254 (unit: μs). interval can be obtained through the aclrtGetOpTimeoutInterval API.
