Abstract :
The authors address one problem of speeding parallel digital system simulation using time warp, namely, that logical processes with errant behavior can incur considerable rollback behavior (analogous to thrashing in paging virtual memories). Consequently, additional mechanisms must be added to an optimistically synchronized simulator to inhibit excessive rollback. They describe a method of adaptively sizing bounded time windows to balance lookahead processing
