A caching and prefetching acceleration method and device for computing equipment based on big data

Abstract

A caching and prefetching acceleration method and device for computing equipment based on big data, which is different from the traditional caching mode in which equipment is optimized, in that the method submits data to the cloud by a large number of caching or prefetching service devices, including these Part of the characteristic data of various applications or network operations on the service device served by the service device. The so-called characteristic data mainly refers to the characteristic data concerned by the cache and prefetch operations, such as the proportion of application read and write operations, I / O Request type, file size, frequency of use, cache optimization experience, hardware type of the cached device on the server side, user group characteristics, etc., the cloud will perform statistics and analysis after receiving the data, dig out optimized cache or prefetch solutions for different applications, and then By means of active feedback or passive response, the optimized caching scheme and prediction scheme are returned to the caching service device for processing, so that the work of the nature of prediction and targeted optimization can be directly performed without re-accumulating cache data for a long time.

Description

technical field

[0001] The product belongs to the field of computer equipment and information science and technology. It is a computer and smart device acceleration method for cross-device interaction based on big data and cloud technology. Background technique

[0002] First of all, it should be noted that the cache referred to in the present invention mainly refers to the disk cache of computers and intelligent computing devices, that is, the cache used to speed up system operation and break through disk performance bottlenecks, rather than video streaming cache or routing web cache.

[0003] Disk caching technology emerged to solve disk speed bottlenecks. The improvement of disk performance lags far behind electronic devices such as processors, which makes the storage system still the performance bottleneck of the entire computer system. Caching and prefetching are two very effective technologies that can improve storage system performance. The idea of ​​caching techno...
