These structures can be accessed using microtags in implementations of “way prediction” within them. A common instance of the thundering herd problem in distributed systems is these structures’ namesake “stampede” under load. A circular doubly-linked list is often used to implement the LRU replacement policy within these structures. (10[2])Conflict, compulsory, capacity, and coherence are the four primary types of “misses” in these structures. (10[1])These structures lie immediately below registers in the memory hierarchy, (-5[1])and (10[1])in modern CPUs they (10[1])are divided into L1, (10[1])L2, (10[1])and (10[1])L3 levels. For 10 points, name these structures that temporarily store data for fast access, (-5[1])which web browser users may frequently “clear.” ■END■ (10[2])
