Description

Obtains the device resource limits of a specified stream.

If the acl.rt.set_stream_res_limit API is not called to set the device resource limits, the device resource limits obtained by this API call are prioritized as follows: device resource limits of the current process (set by acl.rt.set_stream_res_limit) > default hardware resource limits of the AI processor.

Prototype

C Prototype

aclError aclrtGetStreamResLimit(aclrtStream stream, aclrtDevResLimitType type, uint32_t *value)

Python Function

value, ret = acl.rt.get_stream_res_limit(stream,  type)

Parameters

Parameter	Description
stream	Int, specified stream. If 0 is passed, it indicates the default stream.
type	Int, resource type. Currently, Cube Core and Vector Core are supported. For details, see the new data structure by calling aclrtDevResLimitType.

Return Value

Return Value	Description
value	Int, resource limit.
ret	Int, 0 on success; else, failure.
