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