Methods of Selecting Available Cache in Multiple Cluster System

摘要

Aspects include computing devices, systems, and methods for implementing selecting an available shared cache memory as a victim cache. The computing device may identify a remote shared cache memory with available shared cache memory space for use as the victim cache. To select the appropriate available shared cache memory, the computing device may retrieve data for the identified remote shared cache memory or a processor cluster associated with the identified remote shared cache memory relating to a metric, such as performance speed, efficiency, or effective victim cache size. Using the retrieved data, the computing device may determine the identified remote shared cache memory to use as the victim cache and select the determined remote shared cache memory to use as the victim cache.

1. A method of selecting from among a plurality of shared cache memories a remote shared cache memory to use as a victim cache, comprising:
identifying among the plurality of shared cache memories those remote shared cache memories with space available for use as the victim cache; retrieving, for each of the identified remote shared cache memories or a processor cluster associated with each of the identified remote shared cache memories, data relating to a metric for selecting a remote shared cache memory as the victim cache; determining a suitability of each of the identified remote shared cache memories for use as the victim cache based on the metric; and selecting one of the identified remote shared cache memories to use as the victim cache based on the determination.
