Caches are traditionally organized as a rigid hierarchy, with multiple levels of progressively larger and slower memories. Hierarchy allows a simple, fixed design to benefit a wide range of applications, since working sets settle at the smallest (i.e., fastest and most energy-efficient) level they fit in. However, rigid hierarchies also add overheads, because each level adds latency and energy even...
Last-level caches are increasingly distributed, consisting of many small banks. To perform well, most accesses must be served by banks near requesting cores. An attractive approach is to replicate read-only data so that a copy is available nearby. But replication introduces a delicate tradeoff between capacity and latency: too little replication forces cores to access faraway banks, while too much...
