Embodiment Construction

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0051] The term "and / or" in this application is only an association relationship describing associated objects, which means that there may be three relationships, for example, A and / or B, which may mean: A exists alone, A and B exist simultaneously, and A and B exist alone. There are three cases of B. In addition, the character " / " in this application generally indicates that the contextual objects are an "or" relationship.

[0052] The term "multiple" in this app...

Abstract

The invention discloses a cache management method and device, equipment and a storage medium, and belongs to the technical field of storage. The embodiment of the invention provides a method for caching and eliminating material resources of a virtual scene based on temperature information, adopts the temperature information to represent the probability that the material resources are accessed in the virtual scene, uses the positions, corresponding to the temperature information, in the cache queue for caching the material resources, and conducts cache elimination on the cache queue according to the sequence of the positions from back to front. In this way, the cold resources of the virtual scene are eliminated first, and then the hot resources of the virtual scene are eliminated. On one hand, by prolonging the residence time of the hotspot resources in the cache, the probability of hitting the cache when the hotspot resources are accessed is improved, so that the cache hit rate is improved, and the problem of cache pollution is solved. And on the other hand, the cold resources in the cache are removed as soon as possible, so that the cache space is saved.

Description

technical field [0001] The present application relates to the field of storage technologies, and in particular to a cache management method, device, device and storage medium. Background technique [0002] As a storage medium whose access speed is much faster than that of a hard disk and memory, cache is an extremely valuable storage material resource for a CPU (Central Processing Unit, central processing unit) of a computer. Therefore, the computer needs to manage the cache scientifically, so that frequently accessed material resources reside in the cache, and infrequently accessed material resources are promptly cleared from the cache, so as to maximize the use of the cache. In view of this, the computer usually uses a cache elimination algorithm to find which material resource should be eliminated from the cache, and delete the material resource from the cache, thereby releasing the cache space occupied by the material resource. [0003] At present, computers usually per...
