Description
When multiple tasks are delivered to a stream, you can use this API to specify the task scheduling mode to determine whether to continue the next task after a task fails.
Prototype
- C Prototype
| aclError aclrtSetStreamFailureMode(aclrtStream stream, uint64_t mode)
|
- Python Function
| ret = acl.rt.set_stream_failure_mode(stream, mode)

Parameters
Parameter

Description
|
|---|
stream
|
Int, pointer address of the stream to be operated.
The support for the default stream (that is, this parameter is set to 0) varies according to product models.

mode
|
Int, the task scheduling mode to determine whether to continue the next task after a task fails, when multiple tasks are delivered to a stream.
The options are as follows:
- ACL_CONTINUE_ON_FAILURE = 0: default value. If a task fails, the system continues to execute the next task.
- ACL_STOP_ON_FAILURE = 1: After a task fails, the subsequent tasks are stopped.

Description

ret

Int, error code. 0 on success; else, failure.

Restrictions
- This API can be called only once for a specified stream to set the task scheduling mode.
- If the stop-on-failure mode is set for a stream, the stop-on-failure mode also applies to other streams in the context of the stream. This restriction applies to the following product models:
