Resource management method, device and equipment

Abstract

The invention discloses a resource management method, device and equipment, and the method comprises the steps: configuring a first resource which is used for reading a related file of a first application; obtaining a first cache resource occupied when the related file of the first application is read; and if the size of the first cache resource exceeds the size of the first resource, determininga second resource, and clearing the second resource in the first cache resource, so that the remaining resources after clearing the second resource continue to read related files of the first application. According to the method, the size of the first cache resource occupied by reading the related file of the first application is controlled not to exceed the threshold value by setting the threshold value, namely the size of the first resource, so that the situation that the first application unlimitedly occupies the cache resource to affect the operation and use of other application programs is avoided, and the utilization rate of the file cache resource is increased.

Description

technical field [0001] The present application relates to the field of storage, and in particular to a resource management method, device and equipment. Background technique [0002] Linux is an operating system based on Portable Operating System Interface of UNIX (Posix) and Unix with multi-user, multi-tasking, multi-threading and multi-central processing unit (Central Processing Unit, CPU). It can run major Unix tool software, application programs and network protocols, and supports 32-bit and 64-bit hardware. It is a multi-user network operating system with stable performance. The Linux system can be installed on a variety of computer hardware devices, such as mobile phones, tablet computers, routers, video game consoles, desktop computers, mainframes, and supercomputers. [0003] The file cache management algorithm adopted in the Linux system, such as the least recently used (least recently used, LRU) algorithm. It can be used as a page replacement algorithm. The Linux...

[0006] However, the file cache management algorithm (LRU-like algorithm) adopted by the current Linux system has the same right to treat the file cache corresponding to the foreground application and the background application, that is, an application running in the background can obtain unlimited Memory resources and network resources. For example, a background application continuously obtains large-sized video file resources from the network and writes them into the phone's memory, which will cause the background application to occupy and affect the operation of other applications, even the highest priority The file cache resources of the foreground application are all occupied by the large-sized background application video file, which causes performance degradation of the foreground application and other background applications due to insufficient file cache resources required
