Binds a model running instance to a stream.

aclError aclmdlRIBindStream(aclmdlRI modelRI, aclrtStream stream, uint32_t flag)

Parameter	Input/Output	Description
modelRI	Input	Model running instance. The value of modelRI here must be the same as that of modelRI in aclmdlRIBuildBegin.
stream	Input	Stream. The stream must be created by calling aclrtCreateStreamWithConfig, which is used to create a stream of the ACL_STREAM_PERSISTENT type. Passing NULL is not supported. A stream cannot be bound to multiple modelRIs.
flag	Input	Whether the stream runs from the beginning of model execution. ACL_MODEL_STREAM_FLAG_HEAD: Runs from the beginning of model execution. ACL_MODEL_STREAM_FLAG_DEFAULT: Activated based on the branch operator or loop operator during model execution. The stream can be activated by calling aclrtActiveStream. The macros are defined as follows: #define ACL_MODEL_STREAM_FLAG_HEAD 0x00000000U #define ACL_MODEL_STREAM_FLAG_DEFAULT 0x7FFFFFFFU

Parameter

Input/Output

Description

modelRI

Input

Model running instance.

The value of modelRI here must be the same as that of modelRI in aclmdlRIBuildBegin.

stream

Input

Stream.

The stream must be created by calling aclrtCreateStreamWithConfig, which is used to create a stream of the ACL_STREAM_PERSISTENT type.

Passing NULL is not supported. A stream cannot be bound to multiple modelRIs.

flag

Input

Whether the stream runs from the beginning of model execution.

ACL_MODEL_STREAM_FLAG_HEAD: Runs from the beginning of model execution.
ACL_MODEL_STREAM_FLAG_DEFAULT: Activated based on the branch operator or loop operator during model execution. The stream can be activated by calling aclrtActiveStream.

The macros are defined as follows:

#define ACL_MODEL_STREAM_FLAG_HEAD    0x00000000U 
#define ACL_MODEL_STREAM_FLAG_DEFAULT 0x7FFFFFFFU

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