Shared memory management method, device and system

Abstract

The application provides a shared memory management method, device and system. The method comprises the steps of: aiming at a service, creating a control pipe of a shared memory, hitching nodes for implementing the service on the control pipe, wherein the nodes comprise functional nodes implemented by different processes, and one process comprises one or multiple functional nodes; and when receiving to-be-processed data of the service, by the control pipe, controlling the shared memory used for transmitting and processing the to-be-processed data among the nodes so as to implement processing on the to-be-processed data. According to the technical scheme provided by the application, coupling of mutual calling among the processes can be reduced, and system suitability can be improved.

Description

Technical field [0001] This application relates to the field of computer technology, and in particular to a shared memory management method, device and system. Background technique [0002] Multi-process software systems usually need to store data in shared memory. Processes access the shared memory to read data for corresponding processing. Shared memory needs to be created, transferred between processes, recycled, etc. Therefore, in multi-process software systems Need to manage shared memory. [0003] The shared memory management method adopted in the traditional multi-process software system is: according to the data flow path specified by the business in advance, set the calling relationship between the various processes that realize the business; when there is data to be processed under the business, the first The process temporarily applies for a shared memory according to the size of the data to be processed, and then the first process calls the next process to access the s...

AI Technical Summary

Problems solved by technology

[0004] For a multi-process software system, it is necessary to create a process for each business to realize the business and set the call relationship between each process. When there are many types of business in the system, a large number of processes need to be created, and the calls between processes increase. The coupling of the process is broken, and the applicability of the system is low; and in the case of a large business volume, the system may be overloaded

[0005] In addition, in practical applications, the existing business in the system will often change according to actual needs, so developers need to adjust each process and the calling relationship of each process in a targeted manner, and the workload of code adjustment is cumbersome and huge , it is difficult to ensure the timeliness of business adjustment response
