Description
Implements cache memory operations on the device while carrying barrierId. barrierId indicates the barrier ID of a cache memory operation. This API is asynchronous.
Prototype
aclError aclrtCmoAsyncWithBarrier(void *src, size_t size, aclrtCmoType cmoType, uint32_t barrierId, aclrtStream stream)
Parameters
Parameter |
Input/Output |
Description |
|---|---|---|
src |
Input |
Address of the device memory to be operated. Only cache memory operations on the local device are supported. |
size |
Input |
Size of the device memory to be operated, in bytes. |
cmoType |
Input |
Cache memory operation type. |
barrierId |
Input |
Barrier ID. If cmoType is set to ACL_RT_CMO_TYPE_INVALID, barrierId is valid. You can pass a number greater than 0 to this parameter. Use this parameter together with the aclrtCmoWaitBarrier API to wait for the invalid memory operation task with the specified barrier ID to complete. If cmoType is set to other values, the value of barrierId is fixed at 0. |
stream |
Input |
Stream for executing the memory operation task. Only a stream bound to the model is supported. To bind a stream to the model, call the aclmdlRIBindStream API. |
Returns
0 on success; else, failure. For details, see aclError.
