Restrictions
This API cannot be called in the
Before calling an acl API to query or set a compute group, you need to call the dcmi_create_capability_group DCMI API to create a group.
Acl API call sequence: aclrtSetDevice (specifies a compute device) --> aclrtGetAllGroupInfo (obtains the information of all groups) --> aclrtGetGroupCount (obtains the group count) --> aclrtGetGroupInfoDetail (obtains the information of a specified group) --> aclrtSetGroup (sets a group) --> execution of other tasks --> aclrtResetDevice (resets the compute device).
If the group is updated (for example, the dcmi_create_capability_group API is called to add a group or the dcmi_delete_capability_group API is called to delete a group), the service process needs to be restarted.
