Is User Locking Required To Control The Order Of Access To Guarantee Sequential Consistency? |
|
Answer» Sequential CONSISTENCY is independent of USER locking but does require delaying of memory operations at the system level. Precise ordering of operations need not be preordained by the program LOGIC. There just must EXIST a global ordering which is consistent with the LOCAL view observed by each processor Sequential consistency is independent of user locking but does require delaying of memory operations at the system level.
