Sets the timeout (in seconds) for operator execution. If this API is called for multiple times in a process, the last configured interval is used.

For the following product models, you are advised to use the aclrtSetOpExecuteTimeOutV2 API, which returns the actual timeout interval:

Atlas 350 Accelerator Card

Atlas A3 training product/Atlas A3 inference product

Atlas A2 training product/Atlas A2 inference product

aclError aclrtSetOpExecuteTimeOut(uint32_t timeout)

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

Parameter

Input/Output

Description

timeout

Input

Timeout interval, in seconds.

0 means using the maximum timeout.

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

If this API is not called, the default timeout interval of the operator is as follows:

Model	Default Timeout of AI Core Operators	Default Timeout of AI CPU Operators
Atlas 350 Accelerator Card	1091 seconds	28 seconds
Atlas A3 training product/Atlas A3 inference product	1091 seconds	60
Atlas A2 training product/Atlas A2 inference product	1091 seconds	28 seconds
Atlas 200I/500 A2 inference product	1091 seconds	28 seconds
Atlas inference product	547 seconds	28 seconds
Atlas training product	68 seconds	28 seconds

The maximum timeout interval of AI Core and AI CPU operators varies according to the architecture of the product model.

Model	Maximum Timeout Interval
Atlas 350 Accelerator Card Atlas A3 training product/Atlas A3 inference product Atlas A2 training product/Atlas A2 inference product	interval x 254, in microseconds. The value of interval can be obtained by calling aclrtGetOpTimeoutInterval.
Atlas 200I/500 A2 inference product	1091 seconds
Atlas inference product	The maximum timeout interval of AI Core operators is 547s, and the maximum timeout interval of AI CPU operators cannot be set.
Atlas training product	2176 seconds
