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 (10[1])replacement policy within these structures. Conflict, compulsory, (10[1])capacity, and coherence 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 (10[1])L1, L2, and (10[2])L3 levels. For 10 points, name these structures that temporarily store data for fast access, (10[1]-5[1])which web browser users may frequently “clear.” ■END■ (10[1]0[1])
