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 (10[1])structures. (-5[2])Conflict, compulsory, capacity, (-5[1])and coherence (-5[1])are the four primary types of “misses” (-5[1])in these structures. These structures lie immediately below registers in the memory hierarchy, and in modern CPUs they are divided into L1, (10[1])L2, (10[2])and L3 (10[1])levels. (10[2])For 10 points, name these structures that temporarily store data (10[1])for (-5[1])fast (10[1])access, which web browser users may frequently “clear.” (10[1])■END■ (10[3]0[1])
