A method for processing business applications using multithreading

Abstract

The invention relates to a method for processing business application through multiple threads. The method simply includes the steps of creating a business scheduling thread, creating an activation circulating business drive thread, registering a scheduling state detection task, starting a default or assigned processing thread number for business processing types, distributing a lockless queue for each business processing thread, selecting the business processing thread which is not busy relatively, obtaining business processing information from the lockless queue of the selected business processing thread for processing, setting the reference count of a data area in the business processing information to be zero through the business processing thread, and feeding back the information when the business scheduling thread receives the information indicating that processing is finished. The method has the advantages that according to current processing capacity, the concurrence number of the threads is controlled, unnecessary memory copy is reduced, use of a system lock is reduced, new business processing types can be added in the running period, business expansibility of a system is improved, system operation efficiency is improved, resource utilization flexibility of the system is improved, and the development period of the business system is shortened.

Description

technical field [0001] The invention relates to a scheduling technology using multi-thread business processing in information technology, in particular to a method for using multi-thread processing business applications, which belongs to the field of computer communication. Background technique [0002] Multi-threading refers to the technology that realizes the concurrent execution of multiple threads from software or hardware. In a program, these independently running program fragments are called "threads", and the concept of programming using it is called "multithreading". [0003] In engineering applications, multi-threading technology is often used to improve the operating efficiency of software systems. Although with the advancement of hardware technology, multi-processors and hardware with large memory are rapidly popularized, the business to be processed by software systems is also increasing. With the changeable and complex data and the extreme expansion of processe...

Problems solved by technology

[0003] In engineering applications, multi-threading technology is often used to improve the operating efficiency of software systems. Although with the advancement of hardware technology, multi-processors and hardware with large memory are rapidly popularized, the business to be processed by software systems is also increasing. It is changeable and complex, and the processed data is extremely inflated. How to make full use of hardware and system resources to process complex and changeable business under the premise of high efficiency and stability has become a hot topic.

[0004] However, the use of multi-threading technology will face the following problems. If it is not handled properly, the efficiency of multi-threaded business processing will drop significantly, and sometimes it will be lower than that of single-threaded business processing: (1) In a multi-threaded environment Under the circumstances, public resources or codes need to be synchronized and mutually exclusive to ensure the safe operation of the system. They are usually protected by means of critical sections, mutexes or semaphores. At this time, there will be a large overhead. If not handled properly, The performance of multi-thread processing will be greatly reduced; (2) In actual system applications, in some cases, the demand for certain types of business processing in multi-thread processing services will be greater than that of other types of business processing. Resources are redistributed, and more resources are allocated to businesses with large resource requirements to maximize the operating efficiency of the entire system; (3) In a multi-threaded environment, sometimes a large number of messages need to be transmitted between threads, which will Causes excessive data copying, consumes more system resources, and reduces the business processing efficiency of the entire system
