aclSetInputTensorAddr

Function Usage

After aclOpExecutor reuse is enabled by the aclSetAclOpExecutorRepeatable call, if the input device memory address changes, the device memory address recorded in the input aclTensor needs to be updated.

Prototype

aclnnStatus aclSetInputTensorAddr(aclOpExecutor *executor, const size_t index, aclTensor *tensor, void *addr)

Parameters

Parameter

Input/Output

Description

executor

Input

aclOpExecutor that is set to the reusable state.

index

Input

Index of the input aclTensor to be updated, starting from 0.

tensor

Input

aclTensor pointer to be updated.

addr

Input

Device storage address to be updated to the specified aclTensor.

Returns

0 on success; else, failure.
