Few questions about lock about cs431 HOT 2 CLOSED

1/4. No. Ticket lock is also spinning on a location, but it guarantees fairness by designating a location for critical section orders.

2/5. There exists a linear order among all the SC fences in an execution; and the per-thread view at the time that an earlier SC fence is executed, is incorporated to the per-thread view at the time that a later SC fence is executed.

3/6. CLH/MCS lock is different from ticket lock in that in CLH/MCS lock, each critical section is spinning on its own location different from those of each other. MCS parking lock is different from MCS lock in that a thread is parking (i.e. sleeping) if it's not it's turn to enter the critical section.
