Problems solved by technology

[0005] Using IO devices to store data, the external system needs to frequently read and write IO devices, and the IO devices will occupy more resources, which reduces the operating efficiency of the IO devices and cannot meet the requirements of the external system for quick response.
Moreover, in some cases, if the data files are stored scattered and fragmented, the occupation of IO device resources will be particularly obvious. In severe cases, it will affect the performance of the machine where the program is deployed, thereby affecting the normal operation of other programs.

Abstract

The invention discloses a method for controlling a shared memory, which includes: obtaining operation commands and key information of requests for accessing the shared memory sent by an external system; accessing data, corresponding to the key information, in the shared memory according to the operation commands; and outputting access results. Due to the fact that data access is realized in the shared memory, requirement of quick response of the external system can be satisfied even if frequent read-write is implemented by the external system to the shared memory. In addition, access efficiency of the shared memory is not affected by scattered and fragmentary data storage, and accordingly, speed in data storage and data control is enhanced.

Description

technical field [0001] The present invention relates to the technical field of communications, and more specifically, to a method and system for controlling shared memory. Background technique [0002] With the growth of user scale and the continuous development of business, the system needs to process more and more data, and enterprises need to face more and more massive data processing. How to store and control massive amounts of data so that they can be quickly and accurately queried and minimize system resources has become a major problem in the industry. The storage and control of massive data must meet the requirements of speed, accuracy, and low resource occupation. The technical bottleneck lies in the establishment of a complete data storage and control mechanism. [0003] Currently existing technologies mainly use IO devices to store and control massive data. In this way, massive data is stored in the IO device with a specific storage structure, such as splitting ...
