There is a small subset of schools which release their admissions on a designated day and thus may seem to employ the traditional, non-rolling system. But I would warn applicants against considering these schools non-rolling, as this is not truly the case. Even if all acceptances are sent at a later date, secondaries and interview invites will be sent as applications come (on a rolling basis), benefiting earlier applicants just the same as any other school. A late applicant will still be competing for fewer available interview slots, so will be fighting an uphill battle. Thus, these schools effectively have a rolling admissions process as well.
